This kit comes with 3 independent belt-driven Z drives which enables auto bed tramming and can sustain a total 4 KG payload (bed + print) without free fall while steppers disabled. Belt drives and a built-in kinematic coupler eliminate Z wobble.
Besides SK-Go 1 & 2, this kit can also be applied to other cube-style printers with 2020 aluminum extrusions as the frame. The bed is floating on the kinematic coupler but not fastened to bed carriages, the belt drives positions can be adjusted for different build planes, and belts are swappable for different heights.
All pulley housings and stepper mounts are made of 2.5mm-thick 304 steel sheets, which also acts as frame brackets and enhance frame rigidity.
Choose one of the options below and contents will be changed accordingly. For SK-Go owners, since you already have some necessary components, the kit will include only necessary components for upgrade.
