I enjoy the Bambulab printer, it is good at what it does, but I also thought this kind of fun should be more open source, and more affordable. I set out to design a ground up build that would be easy enough for the hobbyist to understand for assembly, but could also be order a bit at a time and built for $450 or under (excluding the pi). This printer has a 300x300 footprint, but a print area of 215x200x210. I can produce a clean bency in 19 minutes on this printer, and still have dialing in to do for gaining even more. I have been playing with this and cleaning up the design through input from a couple of people doing assembly and feedback, as well as assisting in configs for the printer. I gotta say a thanks to them both, so thank you Matt and Chewy.

This printer uses a single z stepper with belted lead screws the same as a Bambu, it also use linear rods on the x & y. Using the belted z, the suggested board is a BTT SKR mini E3 V3, or E3 V2, and it uses sensorless homing for the X & Y. This is a work in progress, but the team and I are brainstorming mods, tweaks, adds, and testing other upgraded features for those who want to go beyond the base design. For those who want to get into fast Corexy printing while still having a decent print area without excessive cost, the base version works quite well.

Love it or hate it, I am always open to suggestions, so feedback is welcome. Come over to the discord and there you will find input, assistance, tips, and tricks.
