I constructed the C beam plate machine following the instructions on the video. It's when i got to the software things got dicey! I finally got grbl downloaded, wired my xpro controller, power supply etc. Put in my settings as per the jpeg in grbl. Now everything is lit up, connected... When I try to move the X Y or Z axis, the z axis buzzes. It buzzes for all three! Doesn't move , just barely buzzes. The other two are quiet. The readout for the axis location changes but nothing moves. Have I left out something? I keep seeing comments about drivers? I am not much of a programmer so it wouldn't surprise me if I missed something. Any help would be nice because the cnc looks too nice just sitting there all lit up and nothing to do!!! And an additional note, all four red leds are lit,and all four go out at the same time when I try to move an axis.
