My Question to supplier:
Hi I am using your DM542T driver and 425oz stepper combo on my new cnc machine.
I can not seem to get the motor to spin the other direction. It only seems to spin on signal high (3.3v) to the dir pin but not signal low 0v on the Dir pin.
I am currently waiting on my breakout board so I have the driver wired directly to my parallel cable for testing.
I have the drivers set for 10micro steps, full current and 3.0 amps on the dip switches.
I have 5v+ going to Pulse+ and Dir+. I have the logic Pulse pin going to Pulse- and the logic Dir pin going to Dir- on the driver.
ENA+/- is not connected.
All pin configuration are correct in Mach3.
All lights are green on the drivers.
All the motors polarities are correct per the motor manual back to the driver.
I assumed at first the motors would not turn the other direction due to only getting 3.3v high signal but after testing I find the motors spin with 3.3v but not low signal 0v.
