Blue red green black.  No other combination will work.
Then you may need to adjust the VREF to get them turning smoothly.

I tried a g95 code with a negative value. It told me the extrusion was too long.
I have no idea how to change the firmware so if that's the answer I need more than just a code.
I tried flipping some wires on the motors but they'd just stutter and stop then. I can't wait to actually print something. I'd really appreciate the help.
