I would guess this pre made code is not normal or not for that controller..
how about some details, like from where did you downloaded it from?
"Mini-Rambo build" doesn’t mean a thing other than to tell us its uses a Mini-Rambo controller.
M907: Set digital trimpot motor
The default are apparently #define DEFAULT_PWM_MOTOR_CURRENT {1300, 1300, 1250}
so your values look really low.
What are you trying to achieve?
I would get the board talking as a first priority, otherwise trying anything is a nightmare.

that firmware code is specifically for the orriginal prusa mk2, not for clones.
It is hard-coded with values for that machine and presumes you have a inductive probe and a v42 bed with the 9 embedded probe points. (also presume things like probe is in same position as the mk2)
From my experience with a mini rambo and that firmware until that firmware completes a calibration via the lcd it will not talk. That will be difficult to complete without the special bed.
It is not a standard marlin, it was based on a old marlin 1.0 from some time back.
You need to compile your own firmware. See [reprap.org]
