PoKeys / Z-axis jumping in feed speed (turning)
« on: August 17, 2021, 10:06:48 AM »
Hello,
When i run a g-code program with G96 (Constant surface speed), my Z-axis jumps in feed speed randomly.
It wants to go full speed for a very short time. so the axis jumps a few cm during the program.

There is no error and when i run the same program again, the moment is different each time.
the code is just normal.

I found out when i run normal (without CSS) or jogging or a MDI G1 code there is no problem.
My RPM readout is stable.
I have the latest version of mach4 hobby (licensed) and pokeys57cnc

what can be the problem?
