Good day everyone,
so im having a problem with the homing of my Z and can’t seem to find the answer. So I’m looking for help/advice, So my machine is a Ramps 1.4 board with a 500w spindle. I have the ground for the z limit attached to the bottom of my spindle with a screw, and I have made a touch plate with a filed knife blade. It’s been filed to the point of removing any sharp edge. So no worries I’m not got to get hurt from it. But anyways here is the problem I’m having.
When I have my spindle unplugged from the AC power, and tell it to home the Z the spindle comes down touches then goes back up and touches a second time only slower. Which is the correct way it should work as I under stand it.
when I have my spindle plugged in (not spinning) and tell the Z to home it travels down and touches the plate once then travels back up like it should, but only comes back down about 75% of the distance to touch a second time.
if I reverse the Z limit wires on the Ramps board the spindle doesn’t even touch the plate.
so any ideas on what I can do to make it work properly without having to unplug the spindle from the AC power each time.
