Prining Issues

[sf01425]

Hello everyone,

I recently completed my build of the Rostock Max V2 printer. This is my first printer and build. After discovering that the cord that goes the computer was bad, a new problem occurred. I went through the calibration and set up, set the Z zero height, and calibrated each tower. When I go to do my first print( peek fan component) the printer heats up to the preset points, goes up to home and touches the end switches, and when it goes down to print it does something random. Every time the I hit print the extruder head goes to a different location than the previous time. It has tried to go past the x axis, z axis, random points in between, and can be anywhere from half an inch from the glass to 7 inches from the glass. The only thing consistent is that it is inconsistent. Can any help me diagnose my problem and help me fix it.
