I also see that you have the 0 ohm resistors (jumpers) set on JP1 - JP6. This will select for 1/16th microstepping and has a conflict with the current firmware.
See How to set up microstepping (#14) · Issues · librespacefoundation / SatNOGS / satnogs-rotator-firmware · GitLab and How to set up microstepping on satnogs-rotator-controller v2.2
I have set some lines in satnogs-rotator-firmware\stepper_motor_controller\rotator_config.h like this to use 1/16th microstepping:
#define MAX_SPEED 6400 #define MAX_ACCELERATION 2400 #define SPR 3200L /*Steps Per Revolution*/
