[ok engineering]

Ok, so I'm rebuilding my 3d printer and I've come across a compatability issue. My controller has step/dir output pins. The drives have the CW-,CW+, CCW-, CCW+ inputs.

I haven't been able to get this to work correctly.

First I tried,
cw- and ccw- together going to ground
cw+ to step signal
ccw+ to direction signal

On controller connector I have

Pin1 = step

Pin3 = direction

Pin2 and pin4 ground to pin 18

Like this the motor runs quickly one direction but very slowly the other direction.

It also travels less in the slow direction.


I undid all that.

Then I,

Set Parameter 4 to 1

I have a DC DC converter going from 24vdc to 5vdc. The positive side of 5vdc output runs to CW+ and CCW+ (pins 1 & 3)

The step signal is run to CW- (pin 2)

The direction signal is run to CCW- (pin 4)

The motor runs one direction until it crashes. No matter how far I tell it to go. Nothing happens in the other direction.

So I'm at a loss. Pleeeeease help.

If I'm understanding it correctly some people have used some sort of logic gate based circuit. Unfortunately for now, that's just over my head.

The board is a azteeg x5 gt
The drives are stonker (China)

Basic component files are attached.
