Reptar XY! - Version Two

youmagine

I design XY blocks with integrated belt tensioners, but after months of use, I've realized they're an unnecessary combination of features and a hassle. Rarely do I want to tighten my belts, adjust 6mm rods, and tweak 8mm bushings at the same time, so having all those features in one part makes each operation more complicated than it needs. Knowing this now, I'm presenting the Reptar XY - Version Two: a simple, lightweight, easy-to-use XY block. The 6mm rods snap into place and are secured by three #2 x 0.5in plastite screws. Belt tensioning is achieved with external belt tensioners or even better, by switching to 303 tooth GT2 belts that don't need any additional tensioners. Those belts last over 1000 print hours without adjustment. Belt indexing is easily done by marking the edges of the belt with white paint after assembly, so you'll never have to adjust your pulleys again!
