Did you end up trying something?

I don’t think I’d really view it as a typical first gen product; Kralyn has been working on it for quite a while and first showed it off 3 years ago. I saw a demo of LDO’s V3.2 at a RepRap Festival and it looks pretty solid.

I haven’t watched the videos in quite a while but I’m sure there are demos of bed leveling, which would be my only real concern with unpacking and repacking it frequently.

That said, since I haven’t owned one myself I can’t say “you should buy this!!1!”. Do you have the budget and time to start with another less-portable model at home to confirm you’re really into printing enough to spend the money on a positron? You don’t need a ton of space to store a Prusa MK4 when it’s not in use, and the robust frame plus fantastic bed probing mean there’s no calibration required after moving it.

If you think about bed adhesion, the forces on a light plastic part from gravity are negligible. Think of how much force it takes to pop a finished part off the bed compared to the weight of the part. When you have adhesion problems, I’m sure the plastic shrinkage is causing pretty large forces (or on a tall part the nozzle bumps the top of the print and has a long lever arm to pry the part off the build surface).

I was expecting Hal

On the other hand, an experienced driver might forget it’s there since they never use it. Add in a high-stress situation, and you get a problem.

Now imagine you’ve been driving the Tesla for a long time and don’t ever use the manual release because you’re not supposed to so you don’t mess up the window. And then imagine you’re in a high-stress situation. That’s how having an unmarked backup can fail.

Plus, that handle doesn’t even look like a normal handle - I have never see a car where you pull up to exit instead of sideways away from the door.

On the other hand, if you never use the mechanical release and have spent a long time only driving your Tesla, wouldn’t it be possible to forget it’s there while in a high-stress situation?

Are the test models ones that come with the printer, or models you’ve found online? If they’re from online, does the printer ship with any you could try? Something sliced by the manufacturer is most likely to work. If those fail, I’d contact customer support.

I have no experience with resin, but is the resin coin stuck to the screen or the build plate? Are you angling the chess piece or trying to print it straight / vertical? My understanding is that resin prints need to be carefully aligned so they’ll peel of the screen, and big flat surfaces like the bottom of a chess piece won’t.

This was more interesting than I expected. Though they didn’t clarify why it costs $700,000, given the context I assume it’s customers on slower devices/connectivity leaving rather than something like bandwidth?

Are you asking about adding a fan, or moving one of your fans from non-PWM to PWM?
