I recently added z endstop to the machine (one end to a conductive magnet and the other end to a copper PCB). I am noticing two problems:
-
If I touch the copper PCB with my finger while homing, it registers that touch as a “Trigger” and considers that position as the home (well it comes down slowly for the second probe but again, if I touch the plate, it registers that as trigger". I have connected the plate to signal and also to negative but get the same thing; it triggers at finger tough!
-
After homing, the machine pauses for me to remove the touch probe and when I resume the print, the machine would occasionally runs to a completely different position and start cutting (like, if it was suppose to start cutting at 10mm x 10mm from origin, it would go to like 70mm x 20mm and start cutting). This is not a programming problem because if I turn off the machine and restart the code, it starts cutting from the correct position. This is boggling my mind! I am guessing this has something to do with the z axis homing.
Anyone experienced this? Any solution? TIA
