CoreXY Ender 3

After a few months away due to a move, I've started to pick up more work on this project and have gotten my prototype operational. I still have several things to add - I'd like to move the electronics to the bottom of the printer, add a third Z motor, and get it enclosed. It's getting there, but I'm thinking I'll be several months out from the final product at least. The video below shows it printing at 150mm/s, 11000mm/s2 acceleration. I have since flipped the motion system around so that the belts aren't crossing in the front, and the motors mount in a way that they act as belt tensioners, similar to how Voron does it.
I've got a rattle somewhere in the toolhead, but I don't plan on taking it apart again until I swap the motion system out with the new design and replace the hotend with a Rapido.

Hi all,

Tanguy recently added me to this project. I've been working on remixing it significantly, as I was wanting to build an Ender 3 conversion that's capable of being fully enclosed, and ideally should have a bit sturdier of a frame. I'm including a screenshot of what I've come up with so far, and am working on the BOM right now. While I'm excited to share it with you, I should warn that this BOM will be significantly more expensive than the original project!

Edit to add - The frame braces shown below are courtesy of @NoWarrenty over at Printables. I remixed the 165mm brace to create the smaller ones: https://www.printables.com/en/model/264710-printer-frame-stiffening-braces-different-sizes

Thanks to @Barzar who did a really great job working on the v0.2 with linear rails !

I am gonna release the current version (V0.1) as a single .step file with the full assembly inside.

As you can see in the videos, the V0.1 prints quite well, but it lacks a lot of little things to make it clean (cable management, proper endstop emplacement etc..)

But I am not gonna do that in this version, I want to make it better with linear rail on X/Y, that will be the V0.2
