In order to limit the use of printed parts as structural components, the kits come standard with aluminum stepper motor mounts, idler mounts and X-axis carriages from Mandala Rose Works. The aluminum beds are milled out of MIC 6 plate to ensure it is has excellent flatness.
We are shipping a complete plug and play wiring harness system with each kit. You no longer have to deal with cutting stripping and crimping your own wires. You will get all components and hardware needed to build the printer, from linear rails to nuts and bolts. All you need is the tools and the time.
A portion of all sales go to J. Steve White and Tony Akens, the guys behind RailcoreLabs who created the open source Railcore project.
