Ho do I get PETG off the build plate? it left a lot of pieces on the plate I cannot get loose.
should use a release agent like light mist of hairspray before printing have you flexed the plate? put in freezer might help

If it’s purely layer 1 stuff that you can’t get off, then just print something big and new on top of it. It will fuse into the new print and come off the build plate with it. This approach is much easier by far than trying to scrape it off while being careful to avoid damage to the build plate.

I’ve never tried this, but perhaps heating the build plate to its limit and trying to pry the stuck parts off carefully while hot, without gouging the surface, may work?

Filling knife or good pain scraper sharp metal is always good to have in hand
Make sure that is the one with sharp end not the blunt one. Then a bit of a cleaning
Heat ? the plate on the bed and a plastic scraper to avoid scratches ?
Go ahead. Knock yourself out. However, unless you’re using float glass as a build plate, as some people do, I don’t know of any build surface that will hold up to repeated scraping with a sharp putty knife like that without accruing cumulative damage.

I’ve had super stuck PETG before and none of the usual advice worked for me to release it. I wound up putting the plate back into the machine and heating the heat bed up until the PETG softened enough that my plastic razor scraper removed everything easy peasy.

I use it constantly , if it is a nice one and user is experienced it survives around 3-9 months( almost everyday use ) on the bambu plates and on prusa plates around 1year-2 years . But for good plates needs to be replaced from time to time any way i replace mine plates as soon as i see
Well, I salute you then. You must have the hands of a talented surgeon. Either that, or the hands that talented surgeons wish they had.
I’m sure I’d gouge things left and right if I were to attempt it on a PEI plate. Matter of fact, I think I did on more than one occasion in years past.

I later heard on an ABS thread that a trick to avoiding the gouging is to round off the two sharp corners.
