Problem on Z axis new PRS standard

[boet]

This is a new machine just set it up. Everything is workinig fine except that the Z cut about 1mm deeper than what the settings are if you do three cuts in succsession it will go about 3mm deeper.

I am working in mm. In a other thread I saw some unit values that looked very different from mine.

This is consistent and it does the same thing every time. The X and Y axis are OK.

The Unit Values [VU] is:

X = 72.1837
Y = 72.1837
Z = -90.2296

I would appreciate some help, I would like to use the machine but with the Z going consistently to deep it is a problem.

Problem solved. I discovered that the Z moves 25% more than what it should. Changed the Z unit value to -72.1837 (20% down from -90.2296) and now it is working correctly
