Hello!
Almost finished my 3d printer build. I'm using RAMPS 1.4 with stepsticks (A4988, sense resistor is 0.05R). All stuff seems to be weorking. But sometimes axis problem appears. I've made a vid to show you. Looks like motor is not powerful enough to move stuff. Z axis on video. Same happens to X and Y axis, but way too rarely. I have two motors on Z axis. X-Y is xycore setup. My motors are Wantai 42BYGHM809 - NEMA17 1.7A per phase, ~2.8-3.06V, 0.9deg/step. RAMPS setup is for 1/16 microstepping. VREF on stepper drivers is 0.64, so it should be nearly 1.7A. So motor should run at max power. But you see result.
Any thoughts would be highly appreciated. This is the only stuff stopping me to start printing:(
