I just built a reprap i3 3d printer.
1. My print head(MK8) temp is 499c stopping all movement but home.
2. My z axis when I tell it to move 200mm it only move 29mm.
3. My printbed reads 0c but that may be do to the printhead stopping the startup checks.
any help would be greatly welcome. I have been stuck for 5 days looking on the internet for some answer. I order new nozzle with thermistor with it because I am getting no uhm reading off the head. I put a light resistor on the board and got it to read so I could move all axisses.
