Core One Heatbed Failure
Hello all,
So I've concluded that I need a new heat bed for my Core One, and the order is in for a replacement (thanks to the support chat for confirming it). I was printing ASA on it but with a non-Prusa textured spring steel plate. I don't think that could have caused an issue, but since it failed after 2 prints (each 6~7 hours, about 14 total), I have a suspicion there is a connection (so just to be sure, I also put in an order for a Prusa satin-textured plate).
Has anyone else seen this with magnetic heat beds in regards to their sensitivity to certain kinds of plates or overall durability? There's no visual damage, it looks brand new - it just doesn't heat up (no resistance accross contacts, thermistor readings change with a hairdryer, etc.)
RE:
some asian textured build plates are very fragile
acompany called 'Energetic 3D store' on Aliexpress, made good cost effective build plates but the cost has gone up to £33.00 or there abouts
regards Joan

I've used BiQu Glacier sheets on my Core Ones no problem.
I have a hard time seeing how a bad sheet can destroy the heat bed.

Just to add to the mystery: I had let the printer sit for a month (the replacement bed took a while to ship given it was over Christmas and New Years, etc.), and other life stuff got in the way. Given the involved process for replacement, I was putting it off. Finally got the gumption to start poking at it again, and raised the bed so I could get to the underside.
Just for the fun of it, controlled the bed to 50C and it worked! Loaded some PETG with the new satin bed, and again, no problems.
I can't rule out bad wiring on the bed or something wrong with the heating element, but - just as a troubleshooting measure, when either running into the issue with the heating element not heating or using the multi-meter test, do try it at different elevations - it might save you some time and money 😉

It can't really. I've used all sorts of esoteric sheets including non metal ones that are clipped to the bed.

I would start by taking the cover off the heatbed connectors and make sure the wiring is not loose.
