Sorry to be so ignorant on the whole GRBL setup. I’m on vacation right now, so my exact settings are unavailable. I have the full step at the moment on all steppers because I read that it is easier to set up that way, and just change later. I think i’ll go to a 1/16th step to get a smoother drive with no power issues. I’m running the A4988 steppers on all four drivers with the Y axis cloned to it using the jumpers. All steppers are set to .975 for the current. my steps are set to 6.25 steps/mm for x/y (200 steps/rotation w/ 16 tooth puller, so 32 mm per rotation). Screw pitch is 2 mm, so I’m at 100 steps/mm. I’ve played with the feed rate, but have no clue what to set them too.
Also, the current in series question for the z axis. I left the current alone on the stepper drivers. Since the z movement isn’t extreme in comparison to the x/y, I thought nothing would be required. I’m understanding that correctly right? without a option to really increase the current, should I leave the Y axis cloned on the A driver, or should I wire that in series as well. Would paralell be better considering that I can control the current with the stepper driver?
Sorry for all of the questions. I appreciate the help!
Thanks,
Brian
