I have a printrbot simple but im having one main issue with the prints. Every time i print something the nozzle hovers over one area and just pumps out plastic. It also will go over certain sections of the piece 3 or 4 times in a row when its only supposed to do 1 pass. This makes half the print come out perfectly but then one corner or side is just a deformed mess. any suggestions or solutions??

What software are you using?

Also check your fish line tension.

im using repetier and i dont think its an issue of the string slipping because it does the rest of the print with amazing accuracy

I use Repetier as well.

In Repetier is you move the axis manually does it follow the commands properly?

i just tried that out and it does control fine for most of the range but i have the xl kit on the bed so it should be able to travel about 250mm but it stops at 100mm(roughly the size of the standard bed)

As described on the @Printrbot site for the XL upgrade:

This GCODE command will resize your bed size in the firmware on the Printrboard:

M211 X153 Z165

then M500 to save
then M501 to check your work
