I dont know if I am missing something or am not understanding the instruction but I cant seem to get the arduino firmware setup for the life of me. I have tried both the instruction on the satnogs website and the Quartapound firmware and am struggling to understand what is going wrong with my setup.
Unfortunately Quarterpound was a little short of comments so I had to put them in myself to understand the firmware behavior. Here is a cut down version showing my comments and modification for different Az/El gear ratios.

2023 December. Az/El Rotor built from a Pan/Tilt pedestal.
-
Augmented changes by Robert Denize to handle Az and El gear ratios not being the same.
-
This is the documentation for satnogs rotator controller firmware
-
for stepper motors configuration. The board (PCB) is placed in
-
satnogs-rotator-controller and is for releases:v2.0, v2.1, v2.2

I see you said 2.0-2.2, I guess I should have mentioned I am building v3.1
ok, I cannot find where you are getting v3.1 from, I certainly cannot find this firmware version. I do suspect there may be confusion with the CNC shield being identified as v3.
Ok, I was just reffering to the rotator version. Not the software. I am following now
What are the different versions, I’ve only ever seen 2 of them that being the standard satnogs firmware and the qourtapound software
