To reiterate the hobby level stuff, and the faffing, after hitting send on the last message, I smelt that special pixie smoke, and looked at mine - which was printing of some reels - and its let all the smoke out of the heatbed cable. Again. So when it finishes, I will have to look at repairing that - I bet it will be at least 2 of the crimps in the connector are crap. Again. But I bet that cable has been on a year or so.
Last time I looked, only available from China. So I need to get one ordered, and find a way to connect it in the meantime... ...or if I can't, consider buying one of those £60 ones I mentioned if I can find one in the EU, and nick the heatbed cable

Plan B could be to unpack the resin printer that arrived months ago, but due to CBA, the box hasn't been opened.
My printer gets so much use, I dont think I could easily live without it for 4-6 weeks
