What I have is an Arduino Uno connected to a breadboard with three A4988 stepper drivers and one Nema 17 stepper. There is a 24v 2a source for the stepper.
This is a trial configuration before moving on. I'm hoping to refurb an old Sherline mill to pay forward to a "young" kid (he is 22, I'm 70). He is a recent grad Mechanical Engineer.
I have ran an example Arduino sketch to prove the wiring is working and the stepper moves.
I flashed the Arduino with GRBL. I installed UGS Platform edition.
I find that I need to reflash GRBL to the Uno each time before I start UGS.
So, I start UGS and use the Setup Wizard. Step 1 is to connect, which works - I end up with "Connected to Grbl 0.9j.
Step 2 is to import settings, which since this is a breadboard test I don't have any.
Step 3 is Motor wiring which is where I fail. I get no movement regardless x, y, z or direction.
Early in the project I was curious how UGS would know which pins I chose on the Arduino for step and direction. I believe that is my issue.
Is there a generic "setting" file I can edit to import in Step 2 of the wizard? What format is is that file?
Is there someplace UGS that I can input the pin information?
Seems I am really close, but have no movement.
Steve.
