Hello,

I bought a RAMPS 1.4 to remplace the original board of the H-1.

After a first connection test, the motors aren't working (they vibe a little). I think it's the connection between the RAMPS and the motors.

I use Printrun as software and Sprinter as firmware

So, how to connect the motors to the RAMPS ? (red wire to 1A port, green to 1B,... for example)

Thanks
