So ive been working on my MP3DP and i got a new arduino mega 2567 and uploaded the firmware to it.
i plugged in the device into the shield and connected the stepper motors, drivers, and the thermistor to make sure it worked. i double checked my wiring and everything is wired correctly from what i can see.
i started repeiter-host and the X, Y, and Z all move in one direction but not in the opposite direction.
any ideas or suggestions to fix the problem?
