Hello everyone, Question does anyone here have experience with pronterface? I've built a Rostock 3d printer, calibrated it, home it, send code G0 X0 Y0 Z0, effector goes to the center of the heated bed, but when I try to print the effector moves to the right rear of the bed to print and the print is off the grid in pronterface. Just wondering if someone could shed some light as to what could be wrong, thanks Jeff.
