I started this project just about 4 months ago now, and it's still very much in the development stage.
LP3D is a low cost, prusa style FDM 3D printer. The printer consists of a heavily cross braced 6mm lasercut frame, with the x-axis and y-axis rack system cut directly into the frame.
Each axis rides on a lasercut roller and slide bearing system, and will (hopefully) be driven by 35byj-46 stepper motors. The brain of the printer is a RAMPS 1.4 board and an arduino mega running a slightly modified version of Marlin to compensate for backlash.
Currently, my largest issue with this printer is building adjustable sliders to account for variance in the lasercut sheets I'm buying, as sheets slightly too thick, (>6.1mm) bind the sliders immediately. This has been surprisingly frustrating, so if anybody has any suggestions, I'd be extremely grateful.
Enjoy this project?
