Hi I have assembled my printer now and almost everything seems to work proper except the auto home button. When i press that button Z and X axis seems to go to its zero position but the Y axis is standing still (I can move Y with the other function “move axis”) also it looks like the printer is setting a new zero/home position everytime I press that button. Can someone help me understand what the problem is?

I have no idea what could cause this specific behaviour… But, seeing your above remark… Check the end position sensors, if they’re fitted & connected correctly?
[Manual section 8: Mounting the endstops]
Hi! Thanks for your reply, I checked if all wires were correct connected and they were correct. But i seems to work properly now when I uploaded the latest firmware to the printer.
Perfect, glad to hear you got it working!
Happy printing.
