During a recent print the mini made a horrible chattering noise during bed leveling. As the printing began, I noticed that the nozzle was actually etching/cutting through the PEI on the build plate. It has bubbled and buckled away from the glass. Not sure if the underlying glass plate was damaged.
Can I remove the PEI? Does this need to be replaced with a new sheet of PEI, or can I use something like painters tape?
Not sure how this happened, but I would like to get the mini back in working form as I love using it and have had it in operation nearly every day since it arrived. It is great and it was heart breaking to see the damage!
