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.

    Well.... Two week update.
    We learned some stuff, like after the refit the machine was not homing to the same location every time, which caused several other problems like non-repeatability and losing the location of the probe rack.

    Sadly none of this fixed the probes failing to calibrate. The controller settings were updated as  mentioned, days were spent trying settings and parameters and adjusting the forces, a new SM-4 modules was sent and tried, to no avail....

    And then, on the sixth day, it was randomly observed that the entire probe head was crooked, like it had never been squared to the machine during the refit (like they slapped in the 4 screws and did nothing else). Likely we were getting excessive force errors because the machine was physically shoving the probes to the limit of the modules. And likely was missing scans because the tip was physically in the wrong location relative to the sphere. 

    Things have been progressing decently since the head was aligned to the machine, scans miraculously got better, excessive force errors disappeared... Hopefully this is now going to be a new page in the tech manual, step one, make sure everything is square! 

    Fingers crossed we make it through probe calibration and verification without learning anything else!
