Inspired by your machine, Aaryn, and excited to revisit CoreXY… I’ve begun my own machine build. I, too, have a fair stash of parts and a Prusa printer always on the ready so I determined to try to adapt your design and use parts I have on hand, as much as possible. Not having appropriate length commercial rails in my stash, I’ve adapted and printed these BB-bearing rails and used some of the zillion or so 608 bearings I have on hand for idlers. I also had a few shorter 2020 extrusions on hand and have elected to use them, primarily just for support. Here’s the basic machine configuration so far…
I’m making just a basic CoreXY machine – probably just another laser engraver – as I don’t expect the printed rails would last too long in a 3dprinter. I’ll probably just add the Z-axis from my earlier post and mount one of the little Neje “6W” (~2.5W) laser modules I have.
I’ll start a new thread for my build. This is just a fun project (NOT a serious machine!) to keep me off the streets but I want to say thank you for the CAD design (your Onshape skills are way better than mine!) and the inspiration to get off my duff. Thanks, Aaryn!
