Tried my brand-new sheet-metal plate with a PETG and it tore off right away. I expect the PETG was too adhered too strongly, but want to be sure it doesn’t look like a defect. I’m very surprised it tore so easily, I guess I was expecting it to be directly applied prepared surface, not glued. The glass plate was, and held up exceptionally well. If I can refurbish it, can I print (with PETG for now) directly on the plain metal and get a good adhesion, or should I attach a new (thicker!!!) PEI sheet? From searches, it appears heating and scraping is the only way to peel it off, followed by removing the adhesive the usual way. [image]

With my previous printer, I had a glass bed, and PETG stuck so well to that, that removing the print tore tiny shards from the glass! Since then, I use painter’s tape with PETG every time, with any print surface.
