Setting up Zenbot 2424 geko g520 controller smoothstepper board and laptop pc with intel core i3 windows 7.
All latest drivers loaded and system runs fine but after running a 4 hour program the Z axis has lost the zero position. X and Y axis are perfect. Running in free airspace so no hitting anything to cause problem, bit touches nothing. No unusual sounds, I watched it for 4 hours several times.
Z returns above zero on 4 separate tests, 0.070, 0.021, 0.030, 0.080 inches. Short run, 30 minutes does not show a problem.
I do not think the problem is mechanical, but suspect control.
Z motor velocity 200 in/min acceleration 30 in/sec/sec
I set the smoothstepper rate to 1 khz, I think those are the units bet don't know how to check.
Dissabled internet for one of the tests without improvement. Tightened router mount for another with no improvement. Checked jog function for accuracy and it is perfect.
I think the fact that the z axis is always high means something but don't know what.
Completely new to CNC and complete idiot so any help welcome.
