Ok so I have been working on building a 3d printer for the past few weeks, I have finally finished off all of the hardware and am working on getting the electronics to work correctly... like getting the motors to move. So here is my problem I hook my x axis motor into its driver and tell it to jump a little but it doesnt move at all (I took the belt off so there is no resistance on the shaft, and the pot on the driver is set to around 0.5v) instead it just makes a hum, so if I put my hand on the motor shaft and turned a little while I tell it to jump it will jump with assistance. So I figured okay maybe it needs more power same thing happens except it needs a little less effort to move. I then figured it would be easier to debug the motor if I put it on the extruder driver. Set it to extrude for awhile in printrun and the motor will move slowly. So I decided to change the value of mm/min and the motor speed was the same. I put the belt back on and it wouldnt move the carriage which I figured so I decided why not and upped the voltage on the pot but no movement just an assortment of noises and everything got really hot so I just it off. I dont think it can be a power problem because when the motor is activated you cant move it atall just when you tell it to jump. So I'm not sure whats wrong, if any of you reprap sages care to lend a hand I'll be very appreciative.
