Hi guys, this is my first post and I'm kind of a noob, so please be kind
So I just managed to assemble my new Prusa i3 kit (bought off ebay) and I got to the calibrating part. I selected auto home from the lcd controller. X axis homes fine, Y axis homes fine, but when Z axis comes close to the end stopper I get a problem. One stepper motor (the left one (next to control board and X motor) stops short of reaching the end stopper, while the motor on the right keeps on going. Now, as the end stopper is on the left side, it doesn't click, so the stepper motor on the right keeps going.. The left one stops at around 8-10mm off the target. It goes up and then comes down again, but only to stop short again.
Any ideas ?
Thank you.
