Forgot plate, damaged printing bed. How fucked am I?
(lm.boing.icu)
I forgot to put back the metal plate on my Anycubic Kobra 2 and pressed print. Managed to stop it relatively quickly but still damaged the heating surface a bit and it chipped away some of the material as you can see. How fucked am I?
Oof. It looks like you need to recalibrate your z height. Your print head went pretty deep there.
I'm not the biggest 3D printer person, but that looks like it's just copper or something? It could just be a heat transfer layer to even out the heat distribution. If so, you should be fine. That area may come out a bit warped at worst, but the damage seems small. Do wait for more responses maybe, as I am not an expert.
You could also try printing again with the plate installed and see what happens. They do sell replacement parts online too.
