G-Code, CAD, and CAM discussions / Re: Z axis losing steps.

Hi,

This issue has been mentioned in other forums and posts by users who found it was one of the following

- loose spindle motor mounting
- loose grubscrews on a flexible coupling which is often found between the Z stepper motor shaft and the Z ballscrew, especially on Chinese CNC routers
- mismatch or looseness on the shank of the cutter in the collet. I found this with what proved to be a 6 mm shank in a 1/4" ER11 collet. Due to the cutting angles, the cutting forces can push or pull a given cutter in or out.
- collapsed thrust bearing on the spindle motor shaft (that would be rare)

Good luck

Hi,

Have a look to see the parallel port is enabled in XP, and that the parallel port address in XP is the same as in Mach3, Config Menu - Ports & Pins - Port Setup (you would usually be using Port 1). See here
