Dual Motors
Posté : 30 mai 2021 05:21
Hi there.
I am doing a mash up of the Root CNC mechanical build with the RS-CNC32 electrical side as it seemed the electronics where better documented with your setup. I have your V1.5 board.
I read that your GRBL32 board could manage 4 axis, and I had read elsewhere that GRBL can duplicate an axis onto the "a" pins. So i assumed (possibly incorrectly) that I could run 4 motors on 3 axis.
I have 2 motors running ballscrews on the Y axis.
I had planned to just run and split the wiring from the Y axis step dir pins to 2 different drivers and then connect those to the two motors.
As i near completion of my build though. I have realized that this will work fine for running any GCode, but it wont really work for the homing if the y axis is not square. Even if i I have 2 limit switches wired up, it'll just stop both motors whenever either one is triggered.
Is there a way to duplicate the Y axis onto the A pins in the software??
Thanks in advance.
