Looking to build on a budget right now. Basically I would dismantle my belt printer to build this and it’s a core xy so I have all the parts including the hot end. I hear you on the core xy, it has its disadvantages, but it makes a clean, easy to make machine. What’s not clean is the Z axis and I agree with you on the screws. I would love a cleaner simpler way of doing z, thats why I am entertaining the idea of a core XZ belt slinger. It does split all the motion up nicely.
Exactly. I made a delta printer about 10 years ago from scratch. Every part has been updated and updated again. Its an adventure.
Do you have any pictures or info on your printer? What would you change?
Have you looked at Klipper to tune out the high speed Issues?
