Done the TinyG upgrade to my 3040 like Jon Lauer however Y axis now has this.
Swapped connection leads and it moves fine so it is the cable I just do not know what part. TinyG screw terminals, Round Connector solder, 4 pin Snap or inside the motor.
Is it wired wrong or is it just one of connection being bad?
I have this same exact problem with a Smoothieboard, and in my case I think I fried one of the stepper drivers. Have you tried measuring the current of both loops straight from the controller pins?
I have not.
I’ve only just hooked the board up within the appropriate connections because documentation is not as helpful. The drivers are still set in the middle location as from factory and the motors are off the machine so no proper load.
When I swap the cable over though it seems to work though. I’ll get testing it again. Any particular current I should be looking for?
