Hello Support,
I found other problem for setting Z motor to home,
I use the same firmware as I did in the past over 200 Printboard PCB, but this time the Z motor can move up- down with manual control, but it can't reach home,
mean if I lift Z for 10mm, it only can down 10mm, no further down.
Different than other motor, no matter the current position, if I press home x, home Y it will alway back to hit the limit switch
pls help what is the board problem

thank
Pong

Dear friend,
1.Please make sure the firmware is not revised.I have sent it to your email box,you can check it again.
2.Did you always press the button "HOME"?You can try to disconnect and reconnect it again.
3.Please check the endstop is well connnected with the board.
4.Please check the chip is normally connect with "S".(See the added picture)
After you have tried,please tell us the results.
Hope it could be solved soon.
Best regards
