Some other things I tried: * Setting a very low max feedrate * Setting a very low max acceleration * Setting a super-low max jerk * Checked for any backlash in the X and Y drivetrains * Checked the stepper driver voltages again With all the kinematics turned wayyy down low, the printer sounds like it's accelerating, buzzes just like before, then moves very slowly and smoothly to home.

I'm still stumped over here. I triple-checked the stepper currents and those are fine. When I just move an axis (i.e., not homing it), it moves smoothly and with no buzzing or missed steps, and neither my steppers or drivers are overheating. It really seems like it's a firmware issue but I have looked over the configuration headers in their entirety a couple times and can't find any other optionsby villainousindustries - General Mendel Topics
Thanks for your reply! In that calculator, for leadscrew-driven systems, I input the following: Motor step angle: 1.8° Driver microstepping: 1/16 Leadscrew pitch: 0.8mm/rev (M5 threaded rods) Gear ratio: 1:1 which gave 4000 as a result. Haven't adjusted the E numbers yet. To clarify, the problem I was describing is happening for my X and Y axes but I haven't tried homing Z yet.

I have been having a lot of weird things happen with my Prusa i3 Rework, mostly due to me having to flash the firmware without having the original configuration, and having to set everything up in the firmware configuration fresh. One of the things that remains to not be working fully is the homing behavior. All axes, X, Y, and Z, have the same problem: when I home an axis, the stepper emits a loby villainousindustries - General Mendel Topics
