Hi
I have built a reprap rostock 3d printer and it is working perfectly except for the print plate size is off, it appears that that somewhere in the program the print size must be limited square with 5.5 inch sides, 140mm. When I try to print something that goes outside of a 5.5inch square it just print a edge there. I can manually move the print head with the hotend to most of my 8 inch square print bed. I am wondering what settings I can try to change to fix this?
The printer is built to spec sizes in every dimension except that the height is taller.
I have a ramps 1.4, run marlin firmware, use Repetier host, and use slic3r.
Thanks
Tanner
