the x and y axis are calibrated beautifully but the z axis wont go up much. i started w/ a steps per mm of 400 on z, now im up to 5000 from 3000 something( which worked well, just not tall enough). the prints didnt seem tall enough so i upped the steps. the problem im having is the z motors glitch when told to go up for the next layer, they will make a 1/8 turn and hum loud when i know the leadscrews should be turning alot more than that.
the 3rd and 4th layers arent tall enough and rub the previous layer. ive read about the digital trimpots but cant find the adjustment part in the configuration.h file. in the pins.h file there is a stepper motor current part, but im not sure how to up the current of just the z motors. i was thinking of switching the motors out w/ kysan nema 17s instead of the cheapos i bought but am not sure if its just a firmware adjustment. im using a prusa i3 w/ rambo, gregs extruder, and a budaschnozzle for 3 mm filament. any help is appreciated!!
