Hi all, I am building my own 3D printer using a Ramps 1.5 and Arduino Mega ADK board. I put the jumpers in, connected it to 12v 5A power supply, and when I connect my stepper motors they all bind up, if I take out the driver for a specific motor it won’t bind up. I checked the leads and both the drivers and motors are receiving 12 volts, my drivers are in correctly and I can even heat my extruded up, so I don’t think it’s a problem with the board. I changed the code in Marlin so that it recognizes my drivers as they are different from the default ones. Also when I go into Marlin and move an axis the motor unbinds and is free moving, if ANYONE can help me please I just can’t figure out what is wrong, thanks.
