    Reprap Snappy 3

    Hello everyone! I've been working on the a Reprap Snappy 3 (https://github.com/revarbat/snappy-r...wiki/v3.0-Home) and all of the axes seem to be working except for the x axis. For context, I'm increasing the dimensions of the build space. To accomplish this I've printed extra x and y rails/sleds and custom made an extra piece to mount to the joiner to make the y rails fit in the increased x sled volume. I've tried different drivers to make sure that I didn't inadvertently burn out a part and I've tried adjusting the driver potentiometer. The wiring on the stepper motor is correct as well as the jumpers being installed for microstepping with the ramps board. I've also ensured the the rails are properly lubricated. Even with all this, the x axis is sticking and the motor is making the stereotypical buzzing noise without moving forward. I don't feel like 2 extra rail parts and 1 extra sled part would be too much weight for the nema17 stepper motor from the parts list. I've run out of alternative reasons why this might not be working though. Would anyone have any thoughts?

    A suggestion, try swapping the x and y plugs on the control board to see if the problem moves to the other axis. That would show if the stepper motor and wiring are ok so you could concentrate on the control board or driver.

      Hello haroldj1956 ! I tried that and it had the same result. Seems like it's skipping a step forward. Just makes a buzzing noise, vibrates a little, and doesn't move forward.
