6XD step signal
-
I've been trying to get the 6XD board to work with a creatbot d600. I've read other posts in this forum, but I'm not sure if anyone has done the conversion with this board. It seems like the stepper drivers are open-collector inputs and I'm unable to control them with sending 5v and connecting to step- dir- en- pins. Per the instructions I've connected a pull-up resistor to the 5v and pins. I'm able to invert the en and dir pins, but I'm not able to invert the step pin. Is there a way to configure this?
Here is my config:

@Josh34 are the motors not moving at all, or moving incorrectly?
Do you have the part number of the stepper drivers that you have connected the 6XD to?
Have you tried leaving the stepper driver enable wires disconnected? For many stepper drivers, this results in the drive being permanently enabled, which means you can concentrate on getting the motor moving and worry about getting the correct enable signal later.
