I have two Bambu filaments loaded in my H2D. PAHT-CF on left nozzle (external spool) and PETG-HF on the right. The filament speed profiles are the Bambu default. When I print my project with PETG, it prints at a nice reasonable speed and it comes out great. But when I switch to PAHT-CF, it appears to be printing in a ridiculously high speed by comparison, and eventually flings and destroys the part. I’m not changing any speed settings.
I don’t, there’s only one object. The only thing I changed is the filament type between prints. Again PAHT prints in psycho speed, PETG prints slower especially around the wall loops.
@Bjorn was talking about the Slicing Result Preview. There’s a Speed option to preview the speed used for every line:
But in your case, it’s simply because PAHT-CF in bambu profile has a much lower Minimum Layer Printing Time (5 seconds) compared to PETG-HF (20 seconds).
So it would not slowdown when printing a small part.
It’s not a ridiculous speed, for PA you hardly need that much of cooling anyway. I don’t think it’s wrong.
