Geeetech Prusa i3 Pro X has some issue with the X-axis home

[jlein]

Hi guys,

I'm just now getting around to trying to fix/upgrade this Prusa i3 Pro X I bought for my robotics team (we have since received a donation from Dremel of one of their machines, but I'd like to get this one working, as well).

I think I've worked out some of the bugs, but now it's doing this weird thing where once it homes the X-axis, the X-pos value on the screen goes from "0" to "402". Trying to start a print when its in this state results in the motors trying to reverse themselves into the frame until they give up or apparently "reach" their destination and it starts printing on that spot or very close to X-home.
Oh, and the heated bed will never reach the setpoint, and does so at the slowest speed possible. I've double and triple checked the wiring and that's good. I might go back and quad-check it, though.

Hi,You can check if your motor wiring is correct. If the motor reverses, you need to change the running direction in the firmware.
