As most of you probably have encountered at some point in time; These two are not the same. That's where the magic of the flow sensor plays a role; then we have a much better idea of what is going on.
I've never really looked at it, but is there that much of a difference on a whole spool? Say, for a roll of PLA, so about 95m of filament, what is the average difference between what we tried to extrude and what was actually extruded? I'm guessing it also depends on what we're trying to print, if tehre's many retractions, grinding problems and such. But, personally, I think the info would still be quite useful. And, once we're down to the end of the spool, we can just measure it by ourselves for the last few meters. It would still save quite a lot of guesswork.

Problem was that dilithium was very difficult with legislation, being an accidental space-time warp risk. So we removed that feature last second.

It's bigger. 330x245x315mm to be exact. And that volume can be used by BOTH nozzles. No more less volume for dual extrusion prints. It has a flow sensor, that works for jam detection as we

As for the flow sensor. We (the Mark2 crowd ) almost finished development for an external flow sensor for the UM2+ including firmware integration. Mechanically it fits to the UM3, but connecting to e

Don't pin me down on it (not a mechanical engineer), but from what i understood it won't be retro-fitted. Not because we don't want to (because we really, really want to! We originally wanted to put it in the UM3 on launch, but had to scrap it weeks before the launch), but because we couldn't get it to fit in the mounting holes that were already there.
Making a retro kit would mean a new backplate and that's a pain in the behind to get right (it will cost a ton of time to replace it and shipping will also be a nightmare)
