I'm looking at making a new printer. I'm thinking a core XY similar to a Voron, but I would be making it from scratch. I'm looking for something I can make reliable and accurate. I want to print PLA, ABS, TPU and more. I have a bunch of parts now that I would stick to.

235mm heated bed Revo hot end Nema 17 motors. BTT E3 mini, although I could use my SKR3 instead.

The easiest would be a bed slinger, but I am open to a Trident style. I like unique and challenging things.

What new features should I include? What should I avoid?

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.

The benefit of core XY is that you don't have a heavy motor riding on the X-axis allowing you to push higher speeds without increasing the rigidity of the y-axis. The downside is the long belt which will stretch a tiny bit meaning a lower accuracy.

With core XZ you don't gain anything as the z-axis is generally not high dynamic meaning the weight doesn't matter at all but still need to eat the downside of a long belt. In my opinion, it is just a stupid gimmick people fell for because is looks novel or cool.

Also core XZ is a bed slinger. With small objects, this is not an issue. The higher they are and the less rigid the print is the bigger the issue of the 3D print itself deflecting gets. With the usual 20cm height and the usual helmet and the like this aspect doesn't matter at all.
