I am mainly concerned as to why this happened and whether or not anything else may be wrong? My glowforge overheated, and I let it cool for a day. Once I tried another cut, the machine was just stuck on “focusing” - I cleaned all the other mirrors, but, when I went to take this one out of the printer head it was slightly stuck (almost as if it had been glued). I was able to get it out, but, this is what the mirror looked like. It will not wipe off, so I am assuming it is damage from the overheating? Or was it the cause of the overheating?
Do you think only replacing the mirror piece will be ok? I am hoping I don’t need a whole new printer head. Everything seems to be ok on the printer head - just worried since it was “stuck” a little when I tried to get it out.
