Safe to use the other side? - Hardware, firmware and software help

You are just knocking back points that may damage the heat-bed surface so any medium grit will do - I would probably use wet and dry paper wet, then finish both sides with HOT water and dishwashing detergent (Dawn/Fairy) to remove working fingerprints.

Cheerio,

Looks like the Nazca lines in Peru.

Thanks Diem. Any particular type of sandpaper?

If there are any raised, sharp edges sand them back, otherwise, Prusa print sheets are double sided to give you a sporting chance ...

Cheerio,

So I had a cascading series of user errors that ended with an "engraved" textured plate. (pic below)

I had a blob monster, which I successfully cleared. I decided to replace the nozzle and all was well for a day. Unbeknownst to me I did not have the thumb screws tightened enough and they slowly unloosened. So, the nozzle head shifted and dropped over time. This was my first nozzle replacement and I guess I was a little too concerned about over tightening. I had replaced the nozzle with a hardened one and this was the result. Oof.

Well, I've recovered from this and put the old nozzle back on as the new nozzle shaft got bent in the process and the filament does not line up to accept the filament. I'll look at that another day.

Do you think there is any concern with using the other side of the textured plate? As it's now engraved I am concerned it will damage the heat bed in the Core One.

Thanks
