Geeetech

I got a new A20M and when I turn it on the printers switch light comes on but the main display doesn't. However after some time it came on and after that it works fine. I have also noticed that when I turn off the switch it will occasionally jump and the display panel will flash. Any ideas on what is going on?

Hi.


This may be a symptom of non-contact wire in the socket.
Simply disconnect it and connect again.

im having a similar issue with the a20m, I had just updated the firmware to the one supporting auto bed leveling (which was working fine until i turned it off to plug in sensor) from geeetech and when I plugged in the bed leveler the fuse blew. I promptly replaced it with the appropriate 5amp , 250volt fuse and it appears to not turn on, the switch lights up but nothing else. the screen light flickers when I move the bed as with most printers so does that mean its not a connection issue?
