Most things that touch (Amateur) Radio/CB will only allow cleartext.
Could you not just have an application that runs your intended text through a cipher and then send that? It's still just cleartext when sent, but gibberish for people other than who it is intended for.
Charge controllers detect open circuit connections, so it will very likely be in a log when suddenly the controller has an open circuit on the input terminals.
Interesting if that happens, but that seems to be caused by additives used by prusa in their filaments then, because from a chemical standpoint the crystalline structure of PLA is simply not dissolvable by acetone. It can cause swelling and delamination of layers, but not actually dissolve it (without additives that mess with the polymer chains)
I set this up a good 25min ago, let's see what happens. It's polymaker polyterra PLA, 3 walls, 15% gyroid infill and some fuzzy skin with default parameters from orca slicer.
So far all I have is very slight color leeching out, but nothing has dissolved so far. I'll let it run for a few days and keep you updated.
You might get some minor surface reaction, but you're sure as hell not able to dissolve PLA in acetone. Leaving a part printed of PLA in acetone will not turn it in to goo like it does with ABS/ASA.
AFAIK they did have some issues on the first of their 3rd gen printers, and only for 110VAC models, 230VAC models were unaffected. And they recognized the issue when it was discovered, fixed it, and shipped replacement parts for affected customers.
The current printers you can buy from them are their 4th gen, haven't heard anything like that for these. They're technically open source, but they make their own weird forked klipper version instead of just using vanilla klipper.
Eh, prusa still seems to be behind the curve, and their insistence on sticking to their old proprietary firmware instead of moving to a more modern approach with klipper and work with the huge community there is IMO a bad move.
Unfortunately they've discontinued the xmax 3, and the newer ones are slightly less open. I would have liked to get a second xmax 3, i got mine for €500 on sale it's been an amazing deal, absolutely insane value for money.
Impressively large print, but I would've probably just built this in plywood or MDF.
