RE: Zero 2 W?
but the printed mount is slightly different for the Zero 2 W
RE: Zero 2 W?
Which is why someone modified the printed mount accordingly.

RE: Zero 2 W?
Oh okay. I didn't notice, I'm rocking the original. Guess I'm not very observant 😀
RE: Zero 2 W?
They also remind everyone to shut down the Zero 2 W first before killing power to the MK3:
Interesting point. Linux filesystems should generally cope with power failures fine thanks to journaling. Better even if the process writing new files uses the proper syscalls etc. But then there's the flash translation layer in the SD card that's IMHO a much weaker link and can wreak some havoc.
But I wonder if PrusaLink does (or could) take advantage of the fact that MK3S can AFAIK detect power going away to prepare for resuming a print from SD card. In theory it could also communicate to the RPi to do a proper shutdown with the remaining power, or even support a print resuming from RPi?
Yes, the SD card itself is failing to write changes, and sometimes just losing all data. Using an "industrial" SD card can avoid this. I've been stress testing this on a few Pi's recently and so far haven't lost any data. Sandisk sells industrial cards, they are smaller and more expensive than what you'd get for a camera, but they're much more durable. I had to buy mine through a reseller on Amazon, they aren't normally available in retail.
RE: Zero 2 W?
If I remember correctly the software can detect power failure but has a very limited time and power window in which to do anything. I think it can just save the point in the print where it failed but that's about it. I may be wrong but I'm sure I read that somewhere.
