Get the creality slicer and chose 3DPrintMill as a printer for slicing.
¶ Upgrades
The original stepper motors come with a 40mm shaft that will get bent by the force of the timing belt. There's a kit that supports the stepper motor axis with a bearing and comes in a nice metallic red.

¶ Maintenance
¶ Belt Tension
The belt tends to move to one side if not properly tensioned. There are two adjustment srews on the front to adjust the front roller position and thus tension the belt. One can use these files:
- cr30-6k-beltadvance.gcode (100mm/s)
- cr30-3k-beltadvance.gcode (50mm/s)
to move the belt faster and check if the belt runs true.
¶ Nozzle change
The printer seems to feed on MK8 nozzles from the images and extra packets on the creality shop. No word on the documentation side of course.
