Re: New build. Can't get Stepper Motor to Work with G-code Sender
I got it to do something by directing +5v from the Arduino to the DIR and PUL +5v terminals on the driver and the negatives from the driver to D6 and D7. There seems to be multiple ways to wire this according to what you follow. No idea if the cheap chinese crap is different or all TB6600s. attached diagram is wrong. If wired the new way only the red LED on the driver lights up and green is off and the motor reacts, but not necessarily in the way I want it. It seems to go back and forth even though I'm only jogging in one direction. But how do I change GRBL to not use D2 and D7 for Pulse and Direction, but D6 and D7 instead? My driver errors out when configured with 2 and 7, which is the way most people have it according to this layout... https://i2.wp.com/blog.protoneer.co....Pin_Layout.png

Figured it out. Arduino Mega 2560 does not use 2-4 and 5-7 pin for the axes. uses 24-26 and 30-32. Also, the Chinese drivers I got seemed to have the right color wires (blue, yellow, green, red) and even in the right order, but internally the middle two wires were switched. Double check you're using the right ones, and don't go off of any colors from any diagram you see. Hold an LED to two of them and turn the motor. if it lights up, it's a pair. Or just hold the wires together without one. If it gets harder to spin it's a pair.
