Random rambling and opinions ahead.
It's $10k if anyone was wondering but as far as commercial products go, that is still peanuts.
Prusa acquired the companies responsible for this product a couple years ago(?) and I believe it is a good thing that this product was in limbo for a bit. (It likely means a more refined product, but just speculation.)
Unfortunately, Prusa is not beyond beta testing with their customers or making false promises about future product features. (re: Prusa Mini, as a good example.) I only say this because if you were planning to buy this for production immediately, I would personally wait a few months.
That previous paragraph sounds bad, and it is, but their support channels are amazing and that is where most of the product cost is. My personal experience with Prusa support has always been excellent.
(I was a Mini early adopter, so I expected some rough edges. Power loss recovery functionality was quietly buried over the last couple of years as their original board+psu wasn't up to the task.)
Thank you for your insight! I forgot that they’d promised power loss recovery, I’ve never had a need for it on my mini.
Agreed on support, too! Always had a good experience
Yeah, I got several replacement bits from them for no charge. It's also super easy to get past their level 1 support if you present an issue clearly and with evidence. (... as opposed to being forced to perform every step in a level 1 playbook. (DiD yOu tUrN iT oN aNd oFf agAiN?))
I have been following the power loss recovery issues on GitHub for a while. They finally came out and said, on GitHub, that they can't implement. It was super shady of them to just quietly delete that feature from their product page.
However: If your first layer is tuned correctly and you lose power long enough for the bed to cool down, the print (depending on the material) will likely pop off the bed anyway so power loss recovery is moot. IMHO, if the print is super important it should be supervised and attached to a beefy UPS.
