Mitutoyo SP25 – best practice and settings for scanning

Recommended Deflection Values:
  1. For calibration:
    1. 0.2 - deflection 1
    2. 0.5 - deflection 2
Note that SM25-4 modules may error out occasionally at these values. If this occurs, increase the deflection 1 value to 0.3 or 0.35.
  1. For measurements:
    1. It is recommended to use the mid or average value of the two calibration deflection values for measurements. Using the values noted above, the recommended deflection value for measurement will be 0.35.
Possible Issues and resolution:

Issues:
Resolution:
It has been observed that with SM25-4, there could be occasional "unexpected touch" error after a tip change during calibration
  1. Browse to folder "C:\ProgramData\QxSoft\CMM-Manager xx\Driver" 
  2. Edit the "IQComUCPCI.ini" file in notepad
  3. Change the INHIBIT_PROBE_DURING_MOVEPROBE value from "0" to "1"
    1. INHIBIT_PROBE_DURING_MOVEPROBE      1
    2. Note: If this value is not already in the file, you may need to copy and add the entry to the *.ini file
  4. Save the file
  5. Launch CMM-Manager 
  6. Run the calibration again
Error E361
This error indicates that "The probe separated from a workpiece when Nominal Scanning is executed."

To resolve, simply increase the deflection limit. For example, increasing the deflection 1 value from 0.2 to 0.3 resolves this issue.

For more details, refer to Mitutoyo error code table.
Error E362
This error indicates that "The probe deflected too much into a workpiece when Nominal Scanning is executed."

To resolve, simply decrease the deflection limit. For example, decreasing the deflection 2 value from 0.5 to 0.4 resolves this issue.

For more details, refer to Mitutoyo error code table.
The probe failed to stop after scanning a feature
  1. Browse to folder "C:\ProgramData\QxSoft\CMM-Manager xx\Driver"
  2. Edit the "IQComUCPCI.ini" file in notepad
  3. Increase the SCAN_STOP_ZONE value, e.g. from "2.0" to "5.0" 
    1. SCAN_STOP_ZONE               5.0 
    2. Note: If this value is not already in the file, you may need to copy and add the entry to the *.ini file
 Error E345 
 This error indicates that "The specified value of the reference displacement is out of the permissible range." 

 This means that the scanning displacement/deflection value being commanded by CMM-Manager is out of the safe range set by the controller.
 
 To resolve, verify that your calibration and execution scan deflection values are within the recommended limits, and adjust if needed.
