Problem with incorrect position in all axis

[Berti]

Hello everyone,

I suddenly have the problem with my CNC milling machine (UCCNC with AXBBE Controller and AC Servos) that the current position is no longer correct for all three axes...

If I e.g. Touch a part and drive around a bit is suddenly the zero point up to 8mm wrong!

When I check an axle with the watch and drive 10mm according to the watch, the display of uccnc also partially deviates by up to 2mm.

If I drive back to zero, I also have different results (+- 1mm)

Taking into account the different axle ratio, the deviation in all three axes is approximately the same.

The strange thing is that only I had a program running, where everything fit. Then I only opened a new program and that’s where the problem began.

Of course, I have already restarted everything, after that everything works briefly as it should, but after 1-2 minutes the same problem is back...

I’m desperate...

Maybe someone can help me...

Thank you in advance.
