SP25 Calibration! (again... yes I searched the forum)

ArkansasBeeper

We just had our machine refurbished, new scales and encodes and controller, everything!

Now we are trying to work through our initial probe calibrations and keep encountering this wonderful error message.
 

Seemingly none of the other poster here were able to get resolution to this message, however it's also very possible I missed it. 

This is one of the probe builds.

These are the parameters we are using, looks like it matches the data sheet the Hex tech provided. The max force is a bit higher as that matched our settings from before. 

So far it looks like only the probes using the SM-4 modules outright fail, some of the others are definitely missing some of the scan points. 

Probe builds are new.
Machine is "new".
PCDMIS is a fresh install on a new PC.
Hexagon tech who was here with is said "as long as you are not planning to scan with those tips just keep hitting ok" but was otherwise unable to correct the issue.

    The force values in the parameter settings are global for all modules.

    You need to go into the PC-DMIS settings editor and adjust them for the longer SM modules.

    You will need to lower the values compared to the parameter settings.

    Adjust the values and then perform a calibration.

    I recommend doing this at both A0B0 and A90B0 to make sure the values can handle the deflection of the probe under its own weight.

    It will be probe build up dependent.

    You will need to lower the values a little, calibrate, perform the scan you were having trouble with until you find the specific value that works for your system.

    A customer that we helped with this issue had a 270mm probe on an SM-4. They were scanning in an A90 orientation. The offset force 1 was changed to 0.6 and the force 2 to 2.0 initially. I know we tuned this further and reduced it more at a later date. I dont remember the final versions.

    What we did do is made a backup of the PC-DMIs settings editor settings so that if anything went wrong, they could reload this and not have to work out these values again.
