The extruder to rail mount is night and day better than the wheels and CF tube mount. Much more rigid. And if you where to do a bowden or ultra light setup it has lots of room to do stuff on the side instead of just out front.
I think I am starting to see signs of my CF tubes cracking on the Repeat, I am getting odd printing artifacts.
I have a nice wire routing loop that seems awesome.
I have yet to work out a great filament loop, but I do think I have an idea for that.
Printed extrusion brackets are no good. Any of the metal ones are good. I think I want to swap some out for wood or plastic milled ones to add some flair.
So far this can be build in a box and does not have to be extrusion based, but I really want to mount that “B” stepper on top of the rail to solve my one issue. If I did that an alternate version would be super easy to make for a “in a box” version.
