Got my new KDEAVI print surface. It is really soft. Just drying it with a rag after washing it and it scratches. Definitely will not be able to use any sort of tool to remove the prints. Currently printing a problematic PETG that has always warped on me w/ my other print surfaces. So far it looks good, I am not able to remove the purge line while the bed is warm.

EDIT: After it finishes I'll try that matte black Bambu PLA. Which had the worst adhesion of any filament I've ever seen.

Have had it for 3 months now. TBH it is simply the best 3d printer part I've ever purchased. PEI sheets are just garbage in comparison. Adhesion is just next level. I do have to use the Bambu razer scrapper to get a lot of parts off. But it does handle it well enough.

EDIT: Like I 100% do not need to worry about the below letting go during print. And this the black matte bambu PLA. Which like I said early had the worst adhesion of any filament I've tested on PEI.

I wasn't getting good results out of some Polylite PETG in spite of giving it a long drying session. It was still coming out extremely brittle.

Had a look through my orders and it was ordered back in June 2021. Maybe 5 years (most of which wasn't being stored vacuum bagged with desiccant) is asking a bit much.

I'll be tossing the filament but probably hanging on to the bare roll.

Whenever I create a 3d model and share it, I always include the step file. As I HATE editing STLs. Like a lot of the time, after uploading the stl to Fusion 360, it simply will not allow me to cut the STL as the geometry is damaged or whatever. Tried for hours on a solution. Finally figured a way.

In Fusion 360, where I need to make the cut, I simple create a new model. Export the base model and the new model as 3MFs, as 3MFs keep the positional data. Then in Orcaslicer, first import the base STL. Then add a 'Negative Part' for the 2nd 'cutting' model. Then Orca can make the cuts. Huge amount of work compared to if someone just released their step files. But it works.

Not sure if it'll make much difference as most higher end modellers have the cad skills to design mods from the ground up, but certainly an interesting option for folks to be able to start with the actual design specs/measurements from the get go.

I'll have to watch the video later but the second nozzle being bowden is something that steers me away from it. There are some cool tricks that can be done with the dual nozzles that I really like such as layering TPU in the middle of a print. But bowden on one nozzle and AMS on the other means stuff like that isn't possible. The H2D I think is what the other one was called is a lot more interesting. Origionally I thought the dual nozzle thing was a gimick but the H2D does deserve some credit after seeing what some people have done with it.

Not only is it out, but "somebody" apparently ordered one?

Mostly want it for support material. Supports with PETG sucks if using same material. And swapping back and forth between PETG and pla is a huge waste, as so much needs to be purged.

I was going to build a 2 hotend machine. But this will save me a whole lot of time on designing one.

So.... using PLA as support for PETG and vice versa?

For PLA, I've found PLA supports still break away great. But PLA can also be used for PETG supports. But with AMS, you need to purge the snot out of hotend, or you'll have adhesion issues for a while after the swaps.
