Enter G-Code Commands in Repetier for Windows?
I am new to 3D printing. I just got a Printrbot Simple Metal, and I've been trying to figure out how to print with it. I'm having trouble calibrating the Z-axis--it's always too high. I've read that you're supposed to type M501 somewhere to find the Z height, then M212 Z (-some amount) to change the offset height. However, I can't figure out where to enter this command, and I haven't been able to find any information on this. One of the tutorials said that there should be a G-code editor at the bottom of the window, but there's not. I'm using a Windows computer. Any advice would be much appreciated.
