Hey,
I ordered my grblshield today for kind of the same purpose as you guys, I don’t need grbl and I just want to use it as a casual motor controller. For my project I will need the grblshield to drive 1 stepper in the X-direction and 2 steppers simultaneously in the Y-direction. So now I have 2 questions that I hope you guys will be able to answer out of your experiences with the grblshield:
1) Is it most convenient to use the same driver for both my steppers in Y-direction (they only need 1,13A/winding) or should I better use the Y- and the Z-direction for this?
2) In both of above cases: how do I address to the motors from my Arduino program? I.e. should I write to more than only pin 8, as you suggested above?
I’m sorry if some (or parts) of my questions are ‘stupid’, but it’s my very first project with Arduino or grblshield so I don’t have any experience.
Thanks in advance,
Arne
PS: if you’re talking about sending step and dir commands, you doing this with (something like) the AccelStepper library, right?
