Gary,
are the pins on the db25 breakout board male?
if so bypass the cable and connect directly to the acorn
and see if it works correctly maybe something wrong with the cable??

Hi Charlie,
It may not be clear, but the connector into that dB-25 breakout is not DB-25. It's a simple 26 pin connector - IDF26?
As explained, I was using that one as it was easier to get to as I tried different combinations of wiring.
Thanks for your reply,
Gary

So what was the issue? Was it the pin out on the board you were using was different than the Acorn DB25? I also noticed that the wizard initially had custom mapping turned off and now it's turned on. Just curious what exactly was wrong before and what you had to change to get it to work properly?

Dan,
I simply followed Marty's instructions verbatim:

Would you please take ONE axis (X). Disconnect the other stepper drives completely
Wire Drive PUL+ to DB25 pin 2
Wire Drive PUL- to DB25 pin 18
Wire Drive DIR+ to DB25 pn 3
Wire Drive DIR- to DB25 Pin 19

Do not connect the ENA+ or ENA- to anything

The difference was using pins 18 and 19 as COM and not as I had them previously.
I found no difference between the DB-25 wiring options, Custom or G540

So the pin out on the bob was different than the Acorn board DB25 pin out. I was just wondering what was causing the problem, glad you got it sorted out. BTW what kind of machine are you installing the Acorn on?
