I pretty much exclusively print PLA models and after printing dozens if not hundreds of models, out of any support material (mostly referring to bambu’s support for pla, and their other one support for pla/petg, as well as petg as interface) I found the support for pla/petg to look best as it’s kind…

The slicer provides settings for breakaway Support as well as PVA. Did you try those settings ? Did you dry the filament ? Guess you saw the info on Bambus webpage (shop) for the filament ? [image]

For PLA or PETG parts, just use the opposite material as support, i.e. use PETG as support for PLA parts and vice versa. That works fantastically with U1, you really don’t need dedicated support filament unless you need it to be soluble. But there is a bug in prime tower where it stacks two incompa…
