General Mach Discussion / Z-axis setup
« on: December 06, 2018, 06:51:04 PM »
Hi. I've had to re-install Mach3 after an electrical storm crashed my PC. I've got a problem with My z-axis - it is jogging OK, but after zeroing and jogging up, when I press "Go to zero" it heads in the wrong direction. I've checked the step pin and dir pin settings, and reversing the dir low active just makes it jog in the wrong direction. The native units are imperial, but I've re-zeroed after loading the metric g-code (which starts with the G21 input). Where to from here? My machine is a RomaxxCNC HS-1 - I've installed the XML provided by the manufacturer. The settings and g-code ran fine previously.
