I would definitely report this bug to BL

Hi all, new and even thou I enjoy reading your comment I don’t have time right now to read them all.
I did try PPS-CF from Bambu on my H2D yesterday. Started well but after 12-15 layers it came lose from the build plate and with no varnings it kept going and after a while there was a lot of filament around the nozzle. I managed to get most away ( I thought) but still not enough so after a bit of stressed fideling I managed to rip 1 wire off. No heating = a lot of trouble.
So now, after a lot of work to clean everything, I’m wait for a new heat plate. Here is what I used maybe all of you with a lot of experience can correct me?
1 - The dryer was on about 12% when the print started. Will let it stay on until next try in a couple of days.
2 - All settings regarding temp according to standard in Bambustudio. Think I will try with heigher temp next time.
3 - Build plate PEI without any adhesive. I would like to be able to print without adhesive if possible.
The print is a plate 15cm x 9cm with a hole in the middle, 10cm x 7cm. 3mm thick and some rise to it. It’s a bracket to be mounted on a pole.
Why is it not possible to use the right nozzle?
I will read all comments soon (maybe today 
)
No you need adhesives. Insisting no adhesives is a weird thought as PEI is considered as a sort of adhesivie already. It’s simply not that strong though.
Temp settings are only “recommended” because they’re usually subdue to changes. Even PLA would warp when you’re printing large parts (and sometimes even adding temperature would not help fix it). So definitely use adhesive, save yourself lots of trouble, especially when nowadays you have lots of choice like Bambu Liquid Glue and new Magigoos.
Unfortunately it didn’t quite make it all the way to the end:
For that reason, I wouldn’t recommend the Polymaker Fiberon brand of PPS-CF for this machine. Whether we blame the filament for being too brittle or the feedpath of the H2D being too tortuous for that particular filament doesn’t matter. Every print becomes Russian roulette, which is not what I want.
I think ultimately I’ll want to implement a better feedpath on the H2D for such filaments, but that will probably have to wait until next fall or winter, as it will take some time to print an alternate lid for the H2D. Meanwhile, I think I’d like to try the Core PPS-CF by Siratech. Maybe it won’t be so brittle.
Whoops. Looks like that’s PPA. I wonder if there is a core version of PPS?
I recant. It must have been an H2D issue rather than a filament issue, because I was able to start a new print without any changes whatsoever (no unloading, loading, or anything of the kind):
