Hello, I am trying to build a 3d printed pen plotter, but when sending a gcode file to the printer, at first it moves well, the it doesnt move at all or it moves in very very small steps. I am using 2byj-48 stepper motors connected to12v with a ramps board, and using 3d printed rack gears for movement(I dont want very accurate movement).
This is the gcode file I am trying to print.
