Being my first 3D Printer build, it took a lot of coaching to get my first print on the bed. Keith was extremely helpful in helping me accomplish this. It's only been a couple of hours, but I'm already hooked! I'm researching a new build, and hope to be printing some of the parts on the TrueUp. Thanks Keith!!
TrueUp Glide
Build in 'Cartesian Style Bots' published by Keith Davis, Apr 14, 2017.
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.
