blob detection
Why can't the MK4S detect a blob? I presume that with the added mass that the current for the motor drivers would increase. Or the tap sensor would show a constant detection. Or the temp sensor would not register proper cooling from the fans.
Why can't the MK4S sense blobs?
RE: blob detection
What? .... Why is there TWO posts and WHY is it in the OpenPrintTag forum? This is NOT where I posted it!

I see it as a fairly difficult problem without sensors e.g. camera. AI might do a "reasonably good job" at it in theory if the printer may borrow your graphics card.
Still, given the low probability of a blob-of-doom and high cost of false detection (failed print) it might do more harm than good in everyday work. I don't want to lose a print over every new non-critical irregularity I run into. That said, it may be possible to find a few meaningful thresholds, the real problem being you'd need to hire a few new guys in support for the "exceptions".
I see Prusa's overall direction selling "printers that are not trying to be smarter than the users". Other vendors see this as an opportunity - of course the feature exists on competing products with said AI/camera on a more modern hardware platform, higher integration level (using state-of-the-art but short-lived chips) etc. Whether any of those boxes will still be in operation five to ten years down the road, time will tell.
A more realistic route, make sure spaghetti-monster-meets-blob-of-doom incidents are prevented by other means - bed adhesion, control warping, understand your printer.
