Forgot plate, damaged printing bed. How fucked am I?
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?
The heating is actually done from underneath this layer I think? I wouldn't worry too much. Clean it so the surface is relatively smooth and try it. If things are messed up, I guess you'd need a replacement from anycubic, but I would try with this one first.
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.
I don't know what printer this is and what anatomy it has. If it is under the actually print layer and this is the heat transfer oder magnetic sheet, just plonk the print sheet on it and maybe avoid the area in the future
I am not familiar with your model of printer, but from looking at Google it looks like it's a typical FDM printer with a spring steel bed. These beds follow this pattern
Spring steel on top
Adhesive magnetic below that
Aluminum bed below that
Heater below that
So your heater is just fine and you gouged the magnet. I would remove any high points from the magnetic layer, so it doesn't push the spring steel up in that area, and carry on.
