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?

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.

I design my own printers and like the challenge. Vorons are expensive and have a ton of parts. I like unique stuff. Ive made my own delta printer and conveyor belt printer. The limitations of those leave me wanting a more traditional style.

I dont like large vehicles either and the trend. But $27k is still not that high, inflation just makes it seem that way. A new RAV4 is cheaper than they were in the 90s despite being s bigger and more premium now.

27k today is the equivalent to $13500 in 1996. I'm guessing the new GTI will be a lot nicer than what you got back then, thats the price of a base Cavalier.

 

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?

Any car that you can't turn off the internal noises is an instant no buy for me. Stupid

27,000 would be among the cheapest new cars available. We've come a long way from when EVs cost more than ICE models.

These tires have been around for 20 years and still haven't been widely adopted.

EVs have a High voltage disconnect. I repaired my EV(inverter) with normal hand tools in my garage. I did have to buy a license and tool for flashing the firmware, but this is a problem in nearly every new vehicle, gas or electric.

EVs do not use more energy than gasoline cars, that's nonsense. The best ICE engine is ~40% efficient plus the losses from braking. Battery electric is closer to 80%. They are only around 10-15% heavier.

Well everything's more expensive than the thing you already own. It's true, most are available in the higher end markets right now, but the Bolt and Leaf are pretty cheap. In the long run, almost all EVs are cheaper than their gas counterparts.

Those drawbacks are endlessly discussed online, to a ridiculous degree. Nothing is universally better, but EVs are almost as close as it gets. If there weren't several whole industries dead set on preventing adoption they would have been adopted much quicker.

 

I'm thinking of building a new printer and would love to be able to make 2 color prints or dissolvable supports. Does anyone have any experience with this. I see 3 paths.

  1. Two hot ends Pros: Most robust No retraction or filament waste Cons: Alignment issues. Reduced travel Dragging nozzle

  2. Dual filament hot end(taichi style) Pros: Easy to mount No offsets Cons: Jamming? Long retraction

  3. Y splitter Pros: easy to mount No offset Compatible with any hot end Cons jamming Super long retraction
