Everything is connected according to that diagram. We are using Universal GCode Sender. Active State lights up green and says “run” when I send a command and is idle otherwise. It also says “ok” after every command but the only movement it does is the X+ and X- (both by manual entry and through the ‘machine control’ screen). We’ve checked the connections multiple times and it seems correct. ;
Also, writing this in case anyone else has a similar problem and ends up reading this, one of the motors we received actually had different colorings for the wires (instead of black-green it was paired black-red). All motors have been tested for continuity.
And when we run the test, we also only see some movement on the X+/-. According to the code, all motors should run after one another while the test is running but it isn’t happening.
