I have this issue with my Xvico x1 3d printer and want to see if anyone here may be able to help. first the printer works great with the gcode on the machines SD card but every time i add something to the SD card with the same parameters and try to print it the printer wont move an inch. anyone know how fix this? does anyone know what kind of gcode the x1 runs? should i just send the x1 back?
