Description

modular coreXY motion system for your mouse

Superior kinematics
Universal mouse mount
Quick belt tensioning with moveable arms
not a bed-slinger
affordable printed linear rails (6mm bbs required)

While this might not become your daily driver, I thought it was a great opportunity to design a functional CoreXY demonstrator, which felt fitting considering the device this was printed on (P1S).

Using the handles and a pointing device, one can more easily appreciate the elegance and mechanics of CoreXY.

The few non-printed components are fairly common, while the 6mm GT2 belt can serve as a jumping-off point for other projects.

Non-printed components:

- 2x 608 bearings
- 4m 6mm GT2 timing belts
- 8x mini foldback clips (printed version underway)
- Multiple 6mm bearing balls or BBs
- 16x M3 * 12 screws

This is super cool, itd be sick if I could find a use for it to give myself a reason to make it. Do you have a specific use case for it?? This is seriously like the coolest thing imo.. Im curious how the printed linear rails worked! Ive printed some 2020 extusions before for one of those screw insert builds that use usb soldering irons. Those worked super well but Ive never found a printed version of linear rails before! Do you or did you lubricate the filament? lol

thanks, honestly it was more of a proof of concept, the frame is too flexible for any high precision task and I didn’t get the time to tune the tolerances and geometry so there’s some backlash and more friction then expected. Personally the rails are far more effective, they work quite well for a printed part and don’t need lubrication. I’ve never tried real ones tho so I can’t really compare them. my loosest carriage would start moving when the rail was tilted about 15 degrees so there’s still far more friction than rollers or any real linear guides but under load they are way better than pla on pla. I’ll try to release a file with only the rail and carriage if you’d like to try them.
