Creality CR10-S Posi-Drive Leveling Upgrade Kit

thingiverse

A Creality CR-10S printer uses a stepper motor on each Z axis screw. Both motors use microstepping to achieve small layer height. Problem is, microstepping was developed for smooth movement, not for accuracy. The two motors can not possibly remain in sync with each other. Even with an auto-level system, by the top of your print job, the extruder is no longer level with the bed. Over mulitple prints this accumulates to where the first layer no longer sticks to the bed on the high side. The Posi-Drive Leveling Upgrade syncs the two screws with a timing belt, guaranteeing that the extruder and bed remain level for the life of the printer.
