Meh, you can get used and working benchtop electric heat treat furnaces for around $500US that would be suitable for home use.

Honestly, my second choice from the Core One would be the Qidi Plus 4. I wanted the X-Smart 3 180³ sized printer as a second machine. But it was discontinued before I got off my butt to buy something. (I ended up with a Bambu mini combo as an impulse buy). But if I was starting over with my first printer, I would seriously consider a Qidi machine.

As a bit of Prusa fan boi myself, I too would recommend the Core One over the Mk4s at this moment. It’s a matter of “Buy once. Cry once.” Cheap often costs more in the long run.

When you are facing a 30 hour print or a long project, a bit extra speed is not only nice but helpful. Plus the heated enclosure can provide access to more engineering grade filaments. While you might not need to print nylon or ABS every day, you will probably find you are going to want to at some point a bit of those types for a project or two. And I believe the Core One also has filtered exhaust air to control nasty fumes that FDM printing can cause, (yes, even PLA has particulates that won’t kill you immediately, but they ain’t good for you either long term).

Personally, I find the MMU to be a god awful design mess. A rat’s nest of loose tubes and spools of filaments, but it does work. I might consider the Box Turtle over the MMU just for the neatness of the design. I find the multi-filament units, cool for very little color printing I do, but it’s the ability to use up spools that don’t have enough left one them to complete a print by switching to a different spool that can finish the print automatically to be far more valuable. It’s cut down my clutter of mostly used spools to near zero. I paid for all that kilo, I’m bloody gonna use it all dammit.

The problem with new PEI sheets everyone sells, is that they make the PEI so thin that it wears out so fast. It’s like when they go to cut a slice off the PEI tree, they damn near miss the whole tree. And the popularity of textured sheets doesn’t help either.

I have a smooth PEI sheet that came with my Prusa Mk3s 6 years ago. It has 1000’s of hours of print times on it. After about 4 years of heavy use, it just wasn’t much good anymore. And I didn’t feel like buying a new sheet, so I took the chance and very lightly hit with some 1000grit wet/dry sandpaper to renew the surface. It now holds better than when it was new. And I can probably sand it again if it ever needs it. But new PEI plates aren’t coated half as thick either. So my Bambu plates will have to be replaced at some point.

They stated 250C was for annealing to final product. That’s a temperature any bog standard toaster oven or kitchen oven can do. Sadly, they said nothing I saw about actual extrusion temps.

Of course. We are nothing, if not stoically nice when we exile someone.

Ain’t nobody ever eating “casserole” anywhere in Minnesota. We eat hot dish here. If you do make a “casserole” in Minnesota, a circle of Lut’ern church ladies will burn your Minnesotan card and make you move to Wisconsin.

We do not eat “tater casserole.”

FDM printing ABS/ASA is far easier and safer than resin printing since most CoreXY printers are enclosed these days. A simple fan and ether venting to the outside world or through activated charcoal air filters is a relatively simple procedure. Printers with all of that filtration are easily purchased these days. Even vapor smoothing can be done outdoors if it’s warm enough.

Their Plus 4 printer is supposed to have multi material box -a la AMS- some time this year. But there hasn’t been much said about it since the release of the Plus 4 model.

The only other one I know of, outside of a dual exturder Voron, is the Qidi I-Fast IDEX printer. It’s expensive, somewhat over $1000, but it has a lot of goodies too. 350C extruder, heat chamber, and a decent sized build volume to print just about any engineering filament.

I got my A1 mini just a month or two before this current unpleasantness, so I was taken unaware. But since I’ve never been interested in using much of the Bambu software ecosystem, switching to LAN mode a month ago has been no big deal for me because I was leaning that direction anyway. And my current firmware version, 1.04 works well so no need to up grade. Nor is Makers World all that important to me.

But there are so many users that just don’t care and will swallow what ever dreck Bambu feeds them.

Roll back the firmware to a version that worked. You still can do that.
