Juno, Kastor & Pollix - Maz And Attero Open Source Core XY 3D Printer

About four years ago now we downloaded our first open source printer design to build our second printer that led to us to having our current 3D printing business that got us out of poverty. We started with a kit that fell apart in two weeks but we were desperate to make something out of 3D printing. Because of how much that person changed our lives by providing the plans to their printer, I am paying it forward for the next person who might be in poverty like we were and have lots of time to build something amazingly life changing.

This printer design is a work in progress and I hope to keep updating with better organization so whoever out there wants to build a Juno, Pollix, or Kastor can do so successfully. I do also plan to release the STEP and Fusion 360 files in the future once I feel I am done making changes for the most part.

This design was inspired by staying somewhat low budget, fully accessible, my partner Attero's spectra line Core XY he built a couple years ago, looking at various other printers, and making these printers the way I wanted them to be. I know there might be flaws or things that don't make sense to the average printer user. I am also not a licensed engineer but just someone who likes to try making things work. ;)

The files with KP, Pollix, or Kastor in the name are intended to be used with those particular designs. For the most part, all the printed parts are mostly the same. Pollix and Juno both use 10mm for the Z drive whilst Kastor uses 8mm. So you could interchange them however you would like.

Should I post all three designs separately? They are mostly the same like I said, so I didn't want to take up too much space on the internet.

I provided as many pictures as I could of the assembled setup. As I get farther I hope to do an assembly video and any other instruction needed.

All three designs are ran on 32 bit system. Juno is ran with a ReArm+Arduino setup. Kastor and Pollix are 32 bit Azteeg X5 Minis.

The three different builds are assembled with both 30x30 and 20x20 extrusions. The only reason I did this was because of the 30x30 being donated to us. Any future builds would be intended as all 20x20 extrusions. A few of the 3D printer part files would need to be edited to accommodate for these changes. I have plans to make another version using all 20x20 but first I have to finish building Kastor and Allanon.

There is a rough draft of the BoM included in this post. I need to get down and go through it again since I changed so many things over the last few months.

More to come in the future! ....
