I need some insight on my Z-Axis auto-zero plate install in Mach3. I have a 4-Axis Xylotex board (XS-3525/8S-4), and am only using XYZ, no A axis.
When I press the autozero-button on the Mach3 screen, the “screen z display goes to 0”, then the spindleZ moves a micro bit, then retracts up to +1 (which is in the script). The spindle never goes negative and makes contact with the touch-off plate.



In advance, Thanks to anyone that reads this.
