DRIVER vs. FULL2WIRE

[Ken L.]

Quick question, I was trying to run my NEMA 23 with a CNC 2M542 Stepper Motor Driver Controller

http://www.sainsmart.com/cnc-2m542-stepper-motor-driver-controller-4-5a-support-nema17-23-34.html

and AccelStepper::DRIVER wouldn't work but AccelStepper::FULL2WIRE does.

I was wondering what the difference was and if there was any downside to it.

Thanks!

Hello,

That controller certainly looks like it should use DRIVER.
I would not expect such a device to work correctly when set to FULL2WIRE.

Did you have Step and Direction wired round the right way?

Cheers.

As it turns out I did had the wires backwards for DRIVER but it works both ways for FULL2WIRE, but it's slower and there's more steps per rev.

OK. AS I said, I would not expect such a device to work correctly when set to
FULL2WIRE.
