A Cartesian printer using bushings for the Z axis instead of wheels or linear bearings. The design also synchronizes two Z axis screws with a timing belt for a level lift. The ratio of the drive pulley and Z axis pulleys produce .005 lift per full step on a 200 step motor, eliminating layer resolution "drift" caused by microstepping.

A beefed up modification of the TrueUp Kit project

A TrueUp Glide modified to use 20x40 V-Slot with a 300x300 bed.

A version of TrueUp using linear bearings/rods for the Z axis. This required enough modification to make a separate OpenBuilds project to avoid confusion for DIYers.

Light enough for high speed #3dprinting Strong enough for high speed #3dprinting

A simplified version of the TrueUp LZ. Designed for classrooms and students
