Hi
I'm trying to figure out how z-homing works. For X and Y axis my printer check for endstop to switch, than came back and check it again. I can request to home these axis multiple time, but the printer act as described every time. For Z axis this is not true:
- With my extruder away from print plate (for security reason, the endstop is near half of Z rods) I set the actual point as Z-home.
- I move extruder 10mm up, then I ask Z to home.
- The extruder go down, hit the endstop and then lift again 1mm.
- If I ask Z to home again, extruder list a little, then go down until the endstop switch and here it remain.
- Every time I ask a z-home, the extruder switch from these two position.
I noticed this while bed leveling and I'm not sure what is my real z zero point.
Any suggestion?
