##1、 Product Overview

In the field of CNC machine measurement, Inspection Plus (Renishaw) and MIDA (Marposs) are the two mainstream macro program software packages. Both are based on the Custom Macro B capability of the CNC system, which achieves calibration, safe positioning, measurement, and compensation writing through calling subroutines using ‘G65’.

###1.1 Inspection Plus Technical System

**Developer: Renishaw, founded in 1973 and headquartered in Gloucestershire, UK, is a global pioneer in probe technology.

**Technical positioning: Regard the measuring head as a sensor for workpiece alignment and size detection, with the workpiece measurement cycle as its core. The tool setting function is delegated to the G37 instruction native to the CNC system for completion.

**System composition * *:

|Level | Name | Description|
|:—–|:—–|:—–|
|Standard | Inspection Plus Standard | Basic workpiece alignment and measurement: single-sided measurement, hole measurement, web measurement, corner measurement, safety positioning, etc., about 15 core macros|
|Plus (Enhanced Edition) | Inspection Plus Plus | Includes all Standard+vector measurement, oblique angle measurement, three-point circle, feature to feature measurement, margin measurement, 4-axis measurement, etc., with approximately 30+macros|
|GoProbe (Simplified Version) | Inspection Plus with GoProbe | User friendly interface based on Standard, aimed at operators rather than programmers|
|Set and Inspect (App version) | Inspection Plus with Set and Inspect | Touchscreen graphical interface, operated through iHMI or external tablet|

**Typical hardware chain: probe (OMP40-2/RMP600, etc.) → optical receiver (OMI-2/OMM-2C) → CNC I/O → macro program

###1.2 MIDA Technology System

**Developer * *: Marpos, founded in 1952 and headquartered in Bologna, Italy, has a deep accumulation in the fields of grinding machine measurement and tool monitoring.

**Technical positioning: Treating the probe system as a complete measurement platform, Part Check and Tool Check are two parallel and independent macro program systems, each with complete calibration, measurement, integrity check, and data output functions.

**System Composition – Part Check Version * *:

**System Composition – Tool Check Version * *:

**Lathe Part Check is also divided into three levels: BASIC/PREMIUM/ULTRAMATE, covering X/Z calibration, C/Y axis measurement, runout detection and other milling functions.

**Typical hardware chain: Probe → E32U interface module (core hub, supporting up to 4 probes) → CNC I/O → Macroprogram

###1.3 Differences in Design Philosophy between Two Systems

Inspection Plus adopts the “different macro numbers=different functions” mode, with a large number of macro numbers but self documented code, so there is no need to refer to the manual for parameter meanings when reading. MIDA adopts the “same macro number+A parameter=different functions” mode, with a small number of macro numbers, but needs to distinguish functions through parameters such as A/B/D/E, which is suitable for teams with unified programming standards.

Identification features of macro number interval:
“`
O98xx/O97xx → Inspection Plus (Renishaw)
O93xx/P937x → MIDA (Marposs)

##2、 Comparison of Programming Systems

###2.1 Macro program calling method

####Common foundation: G65 macro program call

Both software packages use * * G65 * * non modal calling method:

“`gcode
G65 P9xxx [Address parameter ..]
“`

G65 passes independent parameters each time it is called, and releases local variables # 1~# 26, # 33 after the call is completed. **Both explicitly prohibit the use of G66 modal calls * * – probe loops require precise control over the progress of each step to provide safety logic, and modal calls may result in parameter residue or unexpected nested loops.

####Number interval difference

####Collaboration between M-code and macro programs

**Typical M code sequence for Inspection Plus:**

“`gcode
M50 (Turn on probe optical receiver/probe enable)
G04 X1. (Wait for the probe to stabilize, about 1 second)
G65 P9810 Z-5. F3000 (safety positioning)
G65 P9814 D50. Z-20. F1000 (measurement)
G65 P9810 Z100. F3000 (safe return)
M51 (Turn off probe optical receiver/probe disable)
“`

**Typical M code sequence for MIDA (managed through E32U):**

“`gcode
M303 (opens probe channel 1 through E32U)
G04 X0.5
G65 P9311 Z-5 F3000 (safety positioning)
G65 P9312 A1 D50. E5. I0 J0 F1000 R50. (Measurement)
G65 P9311 Z100. F3000 (safe return)
M304 (Close Probe Channel)
“`

**Difference point * *: The M code (M50/M51) of Inspection Plus is defined by the machine tool manufacturer, and different manufacturers may use different codes. MIDA manages probe channels through the E32U module, and M303/M304 are standard M codes defined by Marposs for better consistency. Both systems require the addition of a ‘G04’ pause command after the probe is enabled, waiting for the signal to stabilize.

####Initialize macro

|Software package | Initialization macro | Function|
|:——-|:———|:—–|
|Inspection Plus | * * P9901 * * | Load default system parameter configuration (Stand off, Overtravel, touch feed, etc.)|
|MIDA | * * P9360/O9360 * * | Loading system configuration variables stored in O9366 (# 100~# 150 series)|

The P9901 of Inspection Plus is more inclined towards “soft configuration” – reading the built-in parameter table for initialization; MIDA’s P9360 directly accesses the system variable area (# 100~# 150), and the configuration data storage location is transparent to users, making it easier to debug and modify.

###2.2 Comparison of commonly used macro numbers

####Calibration cycle

|Function | Inspection Plus | MIDA|
|:—–|:—————|:—–|
|Probe length calibration | * * O9801 * * | * * O9301 * * (standard six sided calibration)/* * P9376 * * (tool presetter calibration)|
|Measurement needle X/Y bias | * * O9802 * * | * O9301 * * (integrated in the calibration cycle)|
|Ball diameter calibration | * * O9803 * * | * * O9303 * * (three-point diameter calibration, Premium/Ultimate） |
|Vector measuring needle ball diameter calibration | * * O9804 * * | * O9302 * * (oblique angle calibration, Premium/Ultimate） |
|Automatic calibration of tool presetter | None (dependent on G37 system parameters) | * * P9376 * * (automatic calibration), * * P9386 * * (manual calibration)|
|Offset update macro | * * O9732 * * | No independent macro (read through system variables)|

The design difference of calibration macros: Inspection Plus divides calibration into four independent macros (O9801~O9804), each macro only completes a specific task, and users can run only part of the calibration process as needed. MIDA integrates the length and offset calibration of the workpiece into one macro (standard six sided calibration) in O9301, and determines the length and offset simultaneously through eight directional touch measurements, simplifying the operation process but lacking flexibility – the entire calibration sequence must be fully executed after replacing the measuring needle.

####Workpiece measurement cycle

####Tool measuring cycle

Inspection Plus focuses on workpiece measurement and relies on the native G37 instructions of the CNC system to supplement the tool gauge function. MIDA will design the tool presetter and workpiece measurement as two parallel macro program systems. For workshops that only use standard concentric cutting tools, Inspection Plus combined with G37 is sufficient for use; In scenarios involving non concentric cutting tools or requiring online monitoring of tool integrity, MIDA’s tool alignment system has irreplaceable advantages.

####Special loops and advanced features

####User defined macro extension

Inspection Plus has reserved the * * O97xx * * interval in the numbering system for user-defined macros (O9701~O9732). MIDA recommends that users store custom macros in the * * O9500~O9999 * * range, avoiding the O93xx/O90xx/O91xx and O936x configuration ranges. Both systems support changing macro program behavior by modifying system variables (Inspection Plus # 500 series/MIDA # 100~# 150).

###2.3 Output Variable System

####Public variables (# 500~# 999) are occupied

####Inspection Plus Key System Variables

“`gcode
#500=final measurement result (diameter/width, etc.)
#501=measured value of X-axis
#502=Y-axis measured value
#503=Z-axis measured value
#504=Deviation/Error Value
#505=Reserved
#506=Stand off distance
#507=Overtravel distance
“`

Inspection Plus automatically updates # 500~# 505 after each measurement cycle is completed. These variables are readable and writable, and the user program can read # 500 before and after calling the loop for custom logic judgment. Reading # 500 before executing a new measurement cycle is meaningful – the new cycle will overwrite the value of # 500.

####MIDA O9366 system configuration variables (# 100~# 150)

MIDA uses the * * # 100~# 150 * * series of common variables for system configuration, which can be set through the ` O9360 ` macro program or manual assignment:

|Variable | Function | Typical Value|
|:—–|:—–|:——-|
|* * # 100 * * | Rollback after triggering | 2.0 mm|
|* * # 101 * * | Touch feed rate | 500 mm/min|
|* * # 102 * * | Fast forward speed | 3000 mm/min|
|* * # 103 * * | Maximum movement range | 100.0 mm|
|* * # 104 * * | Safety gap | 3.0 mm|
|* * # 105 * * | Probe overtravel limit | 5.0 mm|
|* * # 106 * * | Counting delay | 50 ms|
|* * # 110 * * | CNC type: 1=Fanuc, 2=Haas, 4=Mitsubishi | 1|
|* * # 113 * * | Measuring head ball diameter radius | 3.0 mm|
|* * # 119 * * | Tolerance Check Enable | 0=Off, 1=On|
|* * # 123 * * | Automatic coordinate system update | 0=no update, 1=update|
|* * # 124 * * | Offset coordinate system number (G54=1… G59=6) | 1|
|* * # 126 * * | Z-axis safety height (absolute coordinate) | 50.0 mm|
|* * # 137 * * | Result storage start # 500 offset | 0|

MIDA uses 51 variables as system level configuration parameters, which has the advantage of centralized management of all configurations. However, in multi program and multi task applications, unexpected modifications to configuration variables can cause abnormal probe behavior and be difficult to troubleshoot. It is recommended to load the configuration in one go through O9360 during CNC startup and protect the # 100~# 150 area from writing.

####Differences in the internal structure of macro programs

The macro call depth of Inspection Plus is relatively shallow (usually 2-3 layers), which is an advantage in systems with limited nested macro call levels. The call depth of MIDA can reach 4-5 layers, and nested depth limitations may be encountered on resource constrained systems. During actual deployment, it is necessary to confirm whether the system parameter # 6005 (macro call nesting depth) is sufficient.

####Variable isolation strategy

**Inspection Plus * * extensively uses local variables (# 1~# 26) for calculations within the measurement loop, minimizing write operations on common variables (# 500~# 999), and only writes measurement results to the # 500 series at the end of the loop.

**The loop of MIDA * * uses both local variables and common variables, and configuration parameters (# 100~# 150) are frequently read inside the loop. The intermediate calculation results may also be written to common variables, which have a higher proportion of usage.

###2.4 Parameter Transmission Differences

####Common Foundation

Both follow FANUC’s G65 address parameter mapping rules:

|Address | Variable | Address | Variable | Address | Variable | Address | Address | Variable|
|:—-|:—-|:—-|:—-|:—-|:—-|:—-|:—-|
| A | #1 | B | #2 | C | #3 | D | #7 |
| E | #8 | F | #9 | H | #11 | I | #4 |
| J | #5 | K | #6 | M | #13 | Q | #17 |
| R | #18 | S | #19 | V | #22 | W | #23 |
| X | #24 | Y | #25 | Z | #26 | | |

####Typical parameter usage of Inspection Plus

|Parameters | Common meanings | Examples|
|:—-|:———|:—–|
|* * D * * | Nominal diameter/size (ring gauge inner diameter, hole diameter) | ` D25. ` indicates Ø 25mm|
|* * Z * * | Z-axis target position (calibration surface, measurement point) | ` Z_ring_top `|
|* * F * * | Feed rate mm/min | F3000|
|* * Q * * | Tolerance/Deviation Related | ` Q1 ` Enable Automatic Writing|
|* * W * * | Workpiece coordinate system number/tool complement number | Write ‘W55’ to G55|
|* * U * * | Tolerance upper limit | ` U0.1 `|
|* * V * * | Lower tolerance limit | ` V-0.1 `|

**Example – Inspection Plus Inner Hole Measurement:**
“`gcode
G65 P9814 D25. Z-10. F1000 Q1 W55 U0.1 V-0.1
“`

####Typical Parameter Usage of MIDA

|Parameters | Common meanings | Examples|
|:—-|:———|:—–|
|* * A * * | Measurement Type/Mode Selection (1=Inner Hole, 2=Outer Circle, etc.) | ` A1 ` Inner Hole Measurement|
|* * B * * | Angle/Second Measurement Direction | B90 90 ° Corner Point|
|* * D * * | Nominal diameter/width/coordinate value | D50|
|* * E * * | Approach distance | ` E5. `|
|* * I/J * * | X/Y axis offset | ` I0 J0 `|
|* * H * * | Write the tool complement number (tool calibration loop) | ` H1 ` Write # 2001|
|* * F * * | Radius knife supplement number (tool gauge loop, optional) | ` F1 `|
|* * R * * | Absolute coordinates of the safety plane | R50|
|* * C * * | Probe Number (Multi Probe System) | ` C1 `|
|* * K * * | Out of tolerance/measurement points | K0.05|

**Example – MIDA inner hole measurement:**
“`gcode
G65 P9312 A1 D50. E5. I0 J0 F1000 R50.
“`

####Summary of Core Differences

|Difference dimension | Inspection Plus | MIDA|
|:———|:—————|:—–|
|* * Type selection * * | Different macro numbers correspond to different functions (P9814=hole, P9812=web) | The same macro number is distinguished by parameter A (P9312 A1=hole, A2=outer circle)|
|* * Safety gap * * | Controlled by built-in variable ‘# 506’ (Stand off) | Explicitly passed by calling parameter * * E * * (proximity distance)|
|* * Tolerance transmission * * | Transmitting upper and lower tolerances through * * U/V * * parameters | Transmitting tolerances through * * K * * parameters (single value symmetrical tolerances)|
|Coordinate update * * | Enable through * * Q/W * * parameter combination (Q=enable, W=coordinate system number) | Enable through * * # 123 * * system variable (O9366 configuration)|
|* * Tool compensation writing * * | Automatically triggered by Q parameter | H/F parameter is used for tool setting instrument, and workpiece measurement is controlled by system variables|
|* * Result Storage * * | Write to the ‘# 500’ series variables (defined by ‘# 501~# 505’, etc.) | Write to the ‘# 500’ series starting from the offset pointed to by ‘# 137’|

**The learning cost of parameter mode: When switching from Inspection Plus to MIDA (or vice versa), the maximum learning cost is not in macro memory, but in the transformation of parameter thinking mode. Inspection Plus makes the code more self documenting, eliminating the need to refer to manuals when reading. MIDA reduces macro number memory but increases the indirectness of code understanding.

##3、 Scenario configuration plan

###Scenario 1: Fanuc 0i/31i system

####Scene features

The FANUC 0i series (0i-D/0i-F/0i-F Plus) and 30i series (30i/31i/32i) are the most popular control systems on CNC machining centers, and are also the native support platforms for Inspection Plus and MIDA. Both fully support Custom Macro B functionality on this platform, without the need for additional porting or adaptation.

####Compatibility confirmation

**System parameter precautions * *:
-Parameter * * # 6000 * * (macro program function): It is recommended to set it to 1 (enable all macro B functions) in versions 0i-F and above
-Parameter * * # 6005 * * (macro call nesting depth): It is recommended to set it to the maximum value (usually 4 or 5) to support multi-level calling in MIDA
-Parameter * * # 6200 * * (SKIP signal): It needs to be set correctly according to the type of probe interface

###Scenario 2: Mitsubishi Meldas M80 System

####Scene features

The Mitsubishi M80/M800 series is a high-end CNC system launched by Mitsubishi Electric, widely used in the Asian market, especially in machining centers in Japan and China. Unlike FANUC, Mitsubishi’s macro program syntax and variable system are basically compatible with FANUC Custom Macro B, but there are slight differences.

####Compatibility status

**Inspection Plus for Mitsubishi * *: Renishaw provides a software version specifically designed for Mitsubishi systems, product code A-4012-2106. This version is recompiled under the macro syntax of the Mitsubishi system, with macro numbers and parameter conventions consistent with the FANUC version, but the underlying skip instruction interface has been adapted for Mitsubishi’s G31 implementation.

**MIDA on Mitsubishi * *: MIDA supports porting to Mitsubishi systems by adjusting system configuration parameter # 110. Set # 110 to 4 (corresponding to Mitsubishi CNC type), and the MIDA macro program will automatically adapt to Mitsubishi’s macro syntax differences. In actual deployment, attention should be paid to:
1. The nested depth of macro calls in Mitsubishi system may be lower than FANUC, which needs to be confirmed first
2. Mitsubishi’s G31 jump signal processing timing is slightly different from FANUC, and it is recommended to use standard ring gauges for verification
3. The range of common variables in Mitsubishi systems may vary, and the availability of # 500~# 999 needs to be checked

####Configuration Plan A: Inspection Plus Special Edition

Suitable for Mitsubishi system machine tools that have selected Renishaw probe hardware.

**Configuration steps * *:
1. Order Mitsubishi Special Edition (product code A-4012-2106) from Renishaw agent
2. Confirm that the Mitsubishi system has enabled the macro program function (bit setting for parameter # 1037)
3. Import macro program files (via CF card or RS232)
4. Verify whether the G31 jump signal responds normally

**Programming precautions * *:
-The macro number is consistent with the FANUC version (O98xx/O97xx)
-Same syntax for parameter passing (G65 P9xxx address parameter)
-G31 skip command compatible, but response time may vary slightly
-Suggest adding a G04 pause before the measurement cycle to wait for the signal to stabilize (at least 0.5s)

####Configuration Plan B: MIGA Migration Plan

Suitable for Mitsubishi system machine tools that have already used the Marposs probe system.

**Configuration steps * *:
1. Set # 110 to 4 in O9366 (Mitsubishi CNC type)
2. Check the macro call nesting depth parameter (parameter # 1128) of the Mitsubishi system to ensure it is ≥ 4
3. Confirm that the public variables # 100~# 150 and # 500 areas are not occupied by other system functions
4. Import MIDA macro program files
5. Use standard environmental gauges to perform O9301 calibration cycle and verify measurement accuracy

**Transplant risk * *:
-Some special functions of Mitsubishi systems, such as high-speed step skipping HSK, may not fully match the touch logic of MIDA
-Partial alarm logic (# 3000) of MIDA may behave differently on Mitsubishi systems
-It is recommended to complete a complete accuracy verification test before formal production

####Scenario 2 selection logic

###Scenario 3: Mazak MAZAK System

####Scene features

Mazak is the largest machine tool manufacturer in Japan, and its independently developed MAZATROL control system includes the Matrix series and Smooth series. The Mazak system supports FANUC compatible macro syntax in standard G-code mode (EIA/ISO mode), but the level of support varies in Mazatlol dialogue mode.

####Compatibility status

**Inspection Plus for Mazak * *: Renishaw offers a version specifically designed for the Mazak system. This version runs in EIA/ISO mode of Mazak, utilizing the Mazak system and FANUC compatible macro program engine. It should be noted that:
1. Must run in EIA/ISO mode (does not support MAZATROL dialogue mode)
2. The G31 jump function of the Mazak system is compatible with standard FANUC
3. The coordinate system bias variables (# 5221~# 5226) of the Mazak system are consistent with FANUC
4. It is recommended to use Inspection Plus Standard version on the Mazak system, and high-level functions need to be verified

**MIDA on Mazak * *: Marposs has limited official support for the Mazak system. Although the macro syntax of MIDA is based on standard FANUC macro B compatibility, the following issues may be encountered in actual deployment:
1. The access permissions of the Mazak system to the O93xx interval may differ from the standard FANUC
2. The signal mapping between E32U interface module and Mazak PMC may require customization
3. MIDA’s # 3000 alarm behavior may exhibit inconsistent behavior on the Mazak system
4. Some advanced features (such as O9098 C-axis search) may not have corresponding functions on the Mazak system

####Configuration Plan A: Inspection Plus Special Edition

Standard configuration scheme applicable to Mazak machine tools.

**Configuration steps * *:
1. Confirm that the machine tool is running in EIA/ISO mode
2. Order Mazak exclusive version from Renishaw
3. Check the available space in the macro program storage area of the MAZATROL system (Smooth series usually provides 256KB~1MB)
4. Import macro program files
5. Verify G31 skip function (execute ‘G31 G91 X10. F100′ in MDI mode)

**Programming Specification * *:
-When programming on the Mazak system, it is recommended to explicitly declare the EIA mode at the beginning of the program:
“`gcode
G60 (switch to EIA/ISO mode)
“`
-After the measurement cycle ends, to return to MAZATROL mode, use:
“`gcode
G61 (switch back to MAZATROL mode)
“`

**Known limitations * *:
-Some early versions of the Matrix series had macro call nesting depths of only 3 layers, so when using Inspection Plus, it is necessary to avoid deep nesting
-The Smooth series is fully compatible with FANUC Macro B, without this limitation
-The parameter protection mechanism of the Mazak system may prevent the writing of O9000~O9999, which needs to be lifted through the MAZATROL management permission

####Configuration Plan B: IDA Limited Support Plan

Suitable for Mazak machine tools that have already used the Marposs probe system, but compatibility risks need to be evaluated.

**Risk control measures * *:
1. Confirm the support status for specific Mazak models with Marposs technical support before purchasing
2. It is recommended to use the MIDA BASIC version (with minimal functionality and lowest compatibility risk)
3. Complete calibration and measurement verification using standard environmental gauges before deployment
4. Prepare a rollback plan: If MIDA fails to function properly, switch to Inspection Plus

**Alternative solution * *: If MIDA has insufficient compatibility on the Mazak system, it can be considered to convert the Marposs probe signal into a standard SKIP signal through E32U and use it in conjunction with the Inspection Plus macro program. But this requires the underlying adaptation of the probe signal and macro program, and it is not recommended for non professional users to try it themselves.

####Scenario 3 Selection Logic

—

###Scenario 4: General CNC system (customized debugging)

####Scene features

In addition to the three mainstream systems of FANUC, Mitsubishi, and Mazak, Inspection Plus and MIDA also support (or have limited support for) the following control systems:

This scenario covers the customized debugging plan for the above system, as well as the general strategy for renovating and upgrading old machine tools.

####Subsystem: Haas

**Haas+Inspection Plus * *: Renishaw offers a Haas specific version. The macro program syntax of Haas system is highly compatible with FANUC, and the macro number system and parameter conventions are consistent with FANUC version after installation. It should be noted that the Haas system has a higher default macro protection level, and the protection for O9000~O9999 needs to be removed in the Setting.

**Haas+MIDA * *: MIDA supports adapting Haas systems by adjusting # 110=2 (Haas CNC type). However, there are differences between the G31 skip function and variable system of Haas system and FANUC. In actual deployment, attention should be paid to:
1. The range of common variables in Haas is different from FANUC (# 500~# 999 are available, but some variables are occupied by the Haas system)
2. Haas’ macro call nesting depth is limited (usually 4 layers)
3. It is necessary to confirm whether the G31 of the Haas system supports high-speed skipping

####Subsystem: Okuma

**Okuma+Inspection Plus * *: Renishaw offers Okuma specific version (OSP version). Okuma’s OSP control system uses a unique variable system (V variables instead of # variables), and the macro program syntax differs significantly from FANUC. Renishaw’s dedicated version has completed syntax conversion and variable mapping, and users do not need to adapt it themselves.

**Okuma+MIDA * *: MIDA does not have a standard supported version on the Okuma system and requires dedicated porting. The cost of transplantation is relatively high, and it is recommended to consider it only when there is already a significant investment from Marposs. The alternative is to use Inspection Plus for Okuma.

####Subsystem: Siemens

**Siemens+MIDA (with native version) * *: Marposs provides the native Siemens version (840D/828D). This version uses Siemens’ SPF subroutine format, and the macro calling method is different from FANUC’s G65:

“`gcode
Siemens format – MIDA example
EXTERN “MIDA_P9312.SPF”(A1, D50, E5, I0, J0, F1000, R50)
CALL “MIDA_P9312” (1, 50.0, 5.0, 0, 0, 1000, 50.0)
“`

**Siemens+Inspection Plus * *: Inspection Plus needs to be converted to SPF format to run on Siemens systems, and the adapted version needs to be obtained through Renishaw technical support.

####Subsystem: Heidenhain

**Heidenhain+Inspection Plus * *: Renishaw offers a Heidenhain specific version, using Heidenhain’s CYCL DEF and TOOL CALL syntax. The macro function is implemented through Heidenhain’s Q parameter system after installation.

**Heidenhain+MIDA * *: Marposs does not provide official support for Heidenhain. If you need to use Marposs probes on the Heidenhain system, it is recommended to use Heidenhain’s universal probe interface (Touch Probe Function) in conjunction with third-party macro programs to achieve basic measurement functions.

####Renovation and Upgrade Plan for Old Machine Tools

Applicable to FANUC 18i/16i system refurbishment projects around 2008 or earlier.

**Typical configuration * *: FANUC 18i-MB+used Renishaw MP3+added MIDA tool setter

**Recommended solution * *: Inspection Plus Standard+MIDA BASIC combination

**Cost benefit analysis * *:
-Probe system investment (Inspection Plus Standard+Renishaw OMP40-2): Approximately ¥ 35000
-Tool presetter input (MIDA BASIC+T25 tool presetter): Approximately ¥ 20000
-Installation and debugging fee: approximately ¥ 8000~¥ 15000
-* * Total investment * *: Approximately ¥ 63000~¥ 70000

**Expected return * *:
-Reduce manual tool alignment time: Save approximately 30-60 minutes per shift
-Reduce first article scrap rate: expected to decrease from 3% to 5% to below 0.5%
-Improve processing consistency: reduce batch size deviation standard deviation by more than 50%
-* * Investment payback period * *: usually 6-12 months (depending on production batch)

####General debugging process

Regardless of which system is chosen, the following debugging process applies to all control systems:

1. * * Preloading Configuration * *: Uniformly load the configuration at the beginning of the program to avoid repeated loading in each loop
2. * * From Simple to Complex * *: Start testing with a single macro (such as secure positioning) and confirm before adding measurement macros
3. * * Verify each step with MDI * *: MDI mode is the safest and stops immediately after the instruction is executed
4. * * Record benchmark value * *: Record the current coordinate system offset (# 5221~# 5226) and tool compensation value before executing the measurement program
5. * * Simulate output instead of actual writing * *: Do not enable automatic coordinate system update during the first debugging, and only enable it after confirming that the measurement results are reasonable
6. * * Establish error recovery mechanism * *: Add status check logic after critical steps

####Common problems and troubleshooting

**The probe does not trigger * *:

**Systematic measurement values that are either too large or too small * *:
1. Calibration failure – failure to recalibrate after probe wear or collision
2. Lack of temperature compensation – When the temperature change in the workshop exceeds ± 5 ° C, consideration should be given
3. Measuring needle bending – check the jumping of the measuring needle before use, if it exceeds 0.01mm, it needs to be replaced
4. Parameter Error – Check if the nominal diameter D parameter is correct (especially when using both imperial and metric systems)

**The measurement value fluctuates greatly and has poor repeatability * *:
1. Wear of probe trigger mechanism – Renishaw OMP series has a trigger life of about 1 million times
2. Cutting fluid interference – rinse the contact surface and retry
3. High feed rate – it is recommended that the F value does not exceed 1000mm/min to achieve a repeatability accuracy of ± 2 μ m
4. Excessive vibration – wait for 0.5~1 second after the spindle is oriented before starting the touch test

**Alarm comparison * *:

**Troubleshooting specific to mixed use systems * *:
1. * * Check # 500 series variable * *: Inspection Plus occupies # 500~# 505, check if the # 137 offset of MIDA has been set
2. * * Check variables # 100~# 150 * *: Confirm that no other program has accidentally modified the configuration parameters of MIDA
3. * * Check the status of modal G code * *: Is there any residual G91 incremental mode after the end of the MADA cycle
4. * * Check macro call stack * *: Confirm that there are no unfinished macro call residues

##4、 Selection reference

###4.1 Performance and Accuracy Comparison

####Touch response speed

The difference in touch response speed between the two systems can be completely ignored in most workshop applications. The E32U module of MIDA adds an additional layer of signal conversion when processing contact signals, theoretically increasing the delay by about 1-2ms. However, with F500 feed, the error is only about 0.01-0.02mm, which is acceptable for most machining tolerances.

####Comparison of Repetitive Accuracy

Under ideal conditions (constant temperature of 20 ° C, standard environmental specifications, clean environment):

|Measurement Type | Inspection Plus | MIDA|
|:———|:—————|:—–|
|Inner hole diameter (Ø 50 ring gauge, F500) | ± 1.5 μ m | ± 2.0 μ m|
|Outer diameter (Ø 50 standard rod, F500) | ± 1.5 μ m | ± 2.0 μ m|
|Single sided position (F500) | ± 1.0 μ m | ± 1.5 μ m|
|Tool length (F500, contact type tool setter) | ± 2.0 μ m (G37) | ± 2.0 μ m (P9377)|

The above data is the factory nominal value, and there may be differences in actual application due to the influence of machine tool accuracy, environmental temperature, and operating specifications.

####Comparison of cycle time (one Ø 50mm inner hole 4-point touch test)

###4.2 Version Selection Decision Tree

The following decision path helps quickly determine the appropriate software version:

“`
Do you need 4-axis/tilt/vector measurements?
∝ – Required → Inspection Plus Plus/MIDA PREMIUM or ULTRAMATE
└ – No need → Continue judging

Do we need non concentric tool measurements or integrity checks?
∝ – Required → MIDA (PREMIUM/MULTIMATE tool setter version must be selected)
└ – No need → Continue judging

Do you need SPC data output/automatic reporting?
∝ – Required → Inspection Plus Plus Plus (P9835)/MIDA ULTRAMATE (O916x)
└ – No need → Continue judging

Do I need to measure with a C-axis/Y-axis lathe?
∝ – Required → MIDA LATHE ULTRAMATE
└ – No need → Inspection Plus Standard/MIDA BASIC (choose one, depending on the probe brand)
“`

###4.3 Scenario Decision Matrix

###4.4 Comprehensive Cost Performance Analysis

**Initial procurement cost * *:
-Inspection Plus Standard+Renishaw OMP40-2+OMI-2 Receiver: Approximately ¥ 30000~¥ 50000
-MIDA Part Check BASIC+MIDA probe+E32U: Approximately ¥ 35000~¥ 55000
-MIDA Tool Check BASIC (including P9376/P9377): Approximately ¥ 15000~¥ 25000
-Inspection Plus tool alignment does not require additional macro program purchase costs (but requires the machine tool to have G37 function installed)

**Long term usage cost * *:
-The macro program upgrade cost of Inspection Plus is relatively low (Standard → Plus option)
-The cost of upgrading the third level version of MIDA (BASIC → PREMIUM → ULTRAMATE) increases step by step
-For users who need to use both workpiece measurement and tool alignment simultaneously, MIDA’s integrated solution may have an overall cost advantage

**Hidden cost * *:
-Training cost: Inspection Plus programming is concise, and the learning curve is relatively smooth
-Fault shutdown cost: MIDA’s E32U fault diagnosis is more intuitive, reducing troubleshooting time
-Expansion cost: When adding laser alignment or multi probe systems in the future, MIDA’s E32U architecture has better scalability

###4.5 Summary of Selection Suggestions

-* * Renishaw probe used+no need for automatic tool alignment * * → Inspection Plus is sufficient, programming is simple, and parameters are intuitive
-* * Marposs probe system (including E32U) has been used * * → MIDA is the best match, integrating tool alignment and workpiece measurement
-Renishaw probe+Marposs tool setter mixed * * → The macro numbers of the two do not conflict with each other and can coexist, but attention should be paid to # 500 variable coordination
-* * Need for powerful tool alignment management (non concentric tool, integrity check, thermal drift) * * → MIDA tool alignment system is more complete
-* * Requires multi axis turning center C/Y-axis measurement * * → MIDA ULTRAMATE’s lathe workpiece measurement version has richer functions
-* * Pursuing concise programming and low learning cost * * → Inspection Plus is easier to get started with
-Renovation and upgrade of old machine tools → Inspection Plus Standard+MIDA BASIC combination offers the best cost-effectiveness

###4.6 Final Recommendation

>The two are not in a zero sum competitive relationship. In actual production scenarios, Inspection Plus excels in workpiece alignment and size detection, while MIDA excels in tool alignment management and tool monitoring. On a machining center equipped with both Renishaw probe and Marposs tool setter, two sets of macro programs can coexist peacefully and complement each other. Understanding their differences – numbering system, parameter conventions, variable occupancy – is the first step in efficient programming.

In practical applications, we suggest:
1. * * Don’t rush to choose either * * – Choose the most suitable software package based on actual needs, and mix it up if necessary
2. * * Establish a variable mapping table * * – In a multi system coexistence environment, clearly record the variable occupancy of each software package
3. * * Training comes first * * – Ensure that both programmers and operators understand the differences between the two systems
4. * * Testing verification cannot be omitted * * – After each hardware replacement or software upgrade, use standard environmental gauges/sample bars for verification

###4.7 Future Outlook

With the transformation of manufacturing towards Industry 4.0 and intelligent manufacturing, in machine measurement technology is also rapidly evolving:

1. The popularization of graphical programming: Renishaw’s Set and Inspect and Marposs’ Ready2Probe are lowering the threshold for macro programming
2. * * Adaptive machining closed-loop * *: Macro program measurement results are directly fed back to the CAM system, automatically adjusting subsequent tool paths
3. Multi sensor Fusion: The E32U architecture of MADA has a natural advantage in multi probe collaboration
4. * * Digital Twin Integration * *: Real time synchronization of measurement data to the digital twin model of the machine tool

No matter how technology evolves, the ability to understand the underlying logic of macro programs – including G65 call mechanisms, parameter passing rules, and variable allocation strategies – remains the core competitiveness of process engineers.

###4.8 Safety Reminders for Use

When using macro programs for in machine measurements, always remember three “don’ts”:

1. Do not use the G00 mobile probe directly without verifying the safety positioning macro – safety positioning macro is the last line of defense against collisions.
2. Do not start a new measurement without clearing the previous measurement result – confirm that the # 500 series variables have been read or reset.
3. Do not mix two systems without confirming the variable mapping table – variable conflicts are the most common and difficult problem to troubleshoot in mixed use scenarios.

**Safety first, understanding first, and verification throughout * * – this is the best rule for making good use of onboard measurement macro programs. Whether you choose Inspection Plus or MIDA for your workshop, or a combination of both, mastering the core differences and practical skills described in this article will enable you to navigate between different systems with ease. The future of CNC machining is automation and intelligence, and macro programs are the fundamental language to achieve this goal.
