Description

XY blocks with integrated belt tensioners are cool. But after designing several of them and using them for months, I've come to the conclusion that they are actually an unnecessary convergence of features and a general pain to use. Rarely (*aka - never*) do I want to simultaneously tighten my belts, adjust my 6mm rods, and adjust my 8mm bushings... so having all of those features in the same part makes each one of those operations far more complicated than it needs to be.
**Knowing that now, I present the Reptar XY - *Version Two:*** a simple, lightweight, *easy to use* XY block. The 6mm rods snap in and are secured by 3 #2 x 0.5in plastite screws.
Belt tensioning is achieved by using any of the external belt tensioners... or... even better... by switching to 303 tooth GT2 belts and doing away with belt tensioners entirely. The belt length on those is perfect without any additional tensioners, and has lasted 1000+print hours without needing adjustment.
Belt indexing is easily achieved by marking the edges of the belt with white paint after assembly - meaning with these blocks, you will never have to adjust your pulleys again!

Hey! Thanks for the design! I've successfully printed and installed them only to realize I've completely forgotten about the limit switches. I see in one of the pictures that there's something that attaches to the back, but I cant seem to find the files anywhere. Before I go ahead and make something crude and utilitarian I was wondering if you actually already have a file for these? I tried to use the ones from your first version but there wasn't enough space between the frame of the machine and the xy block on the front of the machine to make it work. It is quite possible I'm doing something wrong though. Thoughts?

Cheers!

Plastite screws are designed for plastics. They are cutting their threads themself. I guess normal ones will do it.

Paul commented almost 7 years ago

What are plastite screws? Can you use normal screws instead. We don't have such a thing in the UK, I think the imperial dimensions don't help
