Maslow CNC Z-Axis Upgrade "Rigid Lift"

thingiverse

I upgraded the Z-Axis design for the Maslow CNC by utilizing the stock sled with Ring Kit and Z-Axis Kit. My goal was to create repeatable z-axis cuts without overspending. I successfully eliminated the need for bungie cords, which often popped out at inopportune times, and a fusible nut that frequently malfunctioned. So far, my design is at least as rigid, if not more so, and achieves spot-on z height repeatability. I'm currently working on a vacuum skirt/shoe that won't interfere with the z-axis travel.
