WARNING
This is ONLY for the Creality CR-30 Printmill 3D belt printer.
This will BREAK your regular 3d printer. It advances the Z axis 1000 mm @ 100mm/s
-This is a GCODE file, not an STL
-There are 2 files to choose from:
cr30-3k-BeltAdvance.gcode = 50mm/s
cr30-6k-BeltAdvance.gcode = 100mm.s

Use this gcode on your belt printer to assist in calibrating your belt so that it rides nice and centered on the rollers.

1. Run the file.
2. If the belt is staying to the right, Loosen the left OR tighten the right.
3. If the belt is staying to the left, Loosen the right OR tighten the left.
   What you tighten and loosen will be depending on how tight or loose your belt is to begin with.
4. Rerun the file as necessary and allow the belt to "Settle".
5. Repeat steps 1-4
