You’re assuming case sensitive, which is not necessarily true.

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.

I’m not actually seeing it dissolving at all though. It’s softening, sure, but it’s not dissolving like ABS does.

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.

You’re thinking of ABS/ASA, acetone does not dissolve PLA.

Why not just orient it in a different way so a flat surface was touching instead of cutting a part off?

Yeah that’s a terrible orientation for bed adhesion. Have you tried orienting in a different manner that provides a larger contact area with the bed?

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.

They’re fucked even without tariffs…

I did not know…what’s sketchy about it?

No…you can pay more for less, but at least it’s actually yours.

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.

It’s a little hard to see due to low resolution, but it looks like you have small gaps between infill lines. If that’s the case you need to reduce Z-offset to get more squish.

Have you checked that all the grub screws are properly tightened?

Check mechanical connections so it isn’t caused by slipping on gears/rods. Have many hours of printing since you gave it a good thorough service?

Also, what filament type is this?
