1 year ago I've had issues like that due to the stepper stalling and thinking it moved when it didn't. Also depending on how well the gears mesh, there could be backlash which will throw off the position estimate. My guess is it's a combo of both.
I've been designing another rotator with magnetic rotation sensors to be able to have closed loop control instead of counting the steps and hoping it's correct. I'll post it to thingiverse/GitHub once I get around to building it.

Hi, what a fantastic project! I have successfully 3d printed and built the az/el rotor and implemented this software into an Arduino Uno. My satellite software Satpc32 steers the antenna fine, but the antenna won't go home all the way back to the North/0 degree position thus throws off the next track. I was wondering if you had any ideas on what I could check? Thank you for all your effort, great job.
