I have searched and read through most of the posts on setting driver current limits and came to two conclusions…either I’m severely math impaired or I just crave the special attention of my own post. But seriously I think it’s the math…
Just finished my 24"x48" cut area build. I’m running the machine with a Raspberry Pi with the Protoneer Raspberry Pi Hat running at 24v, A4988 drivers set to 1/16 microstepping.
Steppers are: 2.8v, 2.0a per phase, 1.4ohm phase resistance. I am running the XY pairs in parallel with your wiring harness.
Any idea what my currents on the XY pairs and the z motor should be? Looks like the factory defaults are at .55
Thanks in advance for your time and sorry if this is redundant.
