Z probe

Is there a way to use the Z probe to calculate Z height with a single probe in a single location?

I can use the Z probe to home the axis but when the probe is triggered the firmware seems to think the Z level exactly where the probe is triggered is Z0... there is no Z probe height calculated into Z height. I can get the Z offset if I use G32 but not G30 or G29.


  • This is only possible for cartesian printers if you set z min endstop pin to z probe pin. Then firmware detects this as special case. Use homing order XY Preheat Z for this so you can set probing position at a place that works.
