Motors going in wrong direction when autohoming
I manage several Prusas i3 MK2s in our university lab and after uploading the firmware in one of the machines to the v3.1.0, the x and y motors started going in the wrong direction when attempting to home all axis (autohome command). All motors move just fine (i.e. in the correct direction) when moving them individually using the settings > move axis menu.
Any ideas of what could be going on and how to solve this problem?
Thanks.

Try uploading the firmware again maybe, or just go back to the previous firmware version that worked. If everything was going the wrong way (including movement from the lcd) I would recommend to just flip the motor connector on the board.

Hey Gunner,
I tried going back to the previous firmware. The problem is, when I do that, the motors do not move at all, which was also very strange. So, in a nutshell:
- with firmware v3.1.0: motors move in the correct way when moving them individually, but go on the wrong direction when attempting to autohome.
- with firmware v3.0.10: motors don't move at all (they used to).
I could try uploading a different firmware release besides these two and see what happens. I'll do that and let you guys now the results.

So, you have several printers, all the same. One is having issues.
Sounds very much as though that printer has wiring issues or maybe a faulty RAMBo.

Try a Factory Reset, and select the "all data" option. You will have to go through the setup wizard again, takes about 30 mins, if nothing else wrong.
