i sort of got it working, but i get a long ramp up sound, it moves a little bit, then a long ramp down sound. Can anyone tell me what all the code setting should be in the program i upload? And there is a long delay between pressing a calibration button like (move up 50mm) before it actually starts moving,like almost a minute or two.
is there an acceleration setting i should use? looks like maybe its 400 by default (for muve?)
i am assuming that nanodlp uses 1mm as the steps per field, not 1 inch?
my threaded rod is 18 turns per inch
my ramps steps should be 16
my motor is 200 steps per turn
so the equation is 200 * 16 * 18 = 57,600 steps per inch
25.4/57600 = 2267 steps per mm so that is what i uploaded (why does it have xxx/xxx in marlin? what is the second field for?)
my z height is 125mm
#2 i hate ramps arduino
if there is a simple schmatic and instructions for wiring direct with a polulu step stick and pi3 I am down for that too.

does anyone have a working setup and code they would sell?
Ok mechanically i believe it is all working now, that was a battle, i hate these arduino ramps set ups.
when i go to z axis i only get a "tick"
i have a nema 17 and a threaded rod z axis that is 18 turns per inch. (old solidoodle) 200 steps (3600 steps per turn, 57,600 per inch) maybe this is my issue.
the ramps board has all three jumpers so it should be 16 per step
what setting should i have on the set up screen for microstep, lead screw pitch, z axis height (6" x 25.4 = 152.4?)
i dont have any endstops (limit switches) connected.
also any idea what the polulu step stick pot should be at for 1/16? i think i remember .8v but not sure. its at 1.1 right now. getting closer finally!
