    Got tired of the sagging X axis and the pulley mod is limited in help.

    Remixed Stephanburger parts and modified them so they mirror correctly and the idle pulley screw faces the back now.

    Big difference in quality! 0.05 mm layers using a 0.25 mm hot end. Made 20 layers thin lithopanes with this mod without any problems.

    Note that you need to move the existing Y axis motor to the center of the base together with the belt. That will also get rid of the "sideways jerk" that this printer has (someone else came up with the idea, don't remember so chime in). My platform is now made of aluminum since the original fiber board was warping. Tried a 3d printed one but wasn't straight enough for my liking.

    Materials and methods

    You will need an extra stepper, screw, nut and coupler. Got the original parts from QUBD so no need to adjust anything.
