Oh, I didn’t mean to come off as dissing Prusa in general. I ponied up for an XL and it’s night-and-day better than any previous printer I’ve owned.

If this was during an auto level, it’s my humble opinion that this is a manufacturer’s defect in the machine that caused the damage. There should be proper coding to ensure that any increase in sensor pressure by (delta p) halt that machine and that there should be a pressure offset in the sensor such that a loss of signal or anomalous zero reading or lack of reading is done prior to levelling to ensure that a sensor failure has not occurred. My XL freaks out if a fan isn’t spinning at the right speed, so they clearly know that a nominal operational check before the print starts is proper engineering design.

Of course you won’t get anywhere. Unfortunately, a lot of 3D print failures really are user error so I suspect that’s their default response and it takes them a good deal of proof to push them of that mark.

Indeed, I’m not sure even testing is sufficient. My family recently got it (my wife and I visiting my parents), but thought nothing of it for a week. My father had a sore throat, my mother had watery eyes and some nasal congestion. My father masked indoors (because I don’t want a regular cold either) and chalked my mother’s symptoms to seasonal allergies (the cars were covered with Pine pollen all week). Then, on the drive home, my wife felt off. 10 hours in the car together. She slept in the guest room that night and, just for grins, tested for Covid the next morning. She was positive. We called and had my parent’s test - both positive. I tested negative so I packed my things and rented a hotel room for the week and worked there alone. I tested every other day and was never positive, but I cancelled all my client meetings.

I still never “got it” but…is it really feasible I didn’t have some low level? This is my second trip in a car for multiple hours with someone who tested positive the next day. Granted, I’m about 4 vaccines in (2xOG, 1 updated, 1 XBB variant), but so is my wife. I have to think that I had some sub-clinical level of viral load, or at least below the antigen test threshold, but I’m thankful I escaped symptoms.

Yeah, right. I wish I still had that much hair.

Fun fact: the USA is the largest producer of oil in the world, extracting 50% more than it’s closest rivals (Russia and SA) annually. And we’ve been on top for years.

Still cheaper than inkjets

But what if I just like the taste?

But, also, this describes every response to a ML prompt.

When mammals encounter an invasive pathogen, they increase their temperature to assist with the response to eliminate the danger, often requiring only 2-3C above their steady state average. Maybe we aren’t actually causing climate change and Earth is just fighting off the human infection.

XL feels like using cheat codes.

If you print with incompatible filaments (materials which don’t bond/adhere) you can get cheap, nearly perfect breakaway supports. I’ve done some rocket parts on my PrusaXL and it’s certifiably magic.

A movie-set must have certain features (full, even, ready for shooting on schedule) and there are millions of dollars on the line - you don’t just plant a field and hope it meets spec - I would think someone was making case it would be ready for filming. That that’s time and effort. The movie industry unions have livable - one might say exceptional - wages, even for someone just checking to make sure the corn field is maturing properly, much less planting and tending the crop.

An un-referenced medium article says he invested $100,000 in the corn field and he generated $162,000 in revenue, with no indication of the expenses of monitoring or harvesting. The best result would be $62k (compared to the $20,000,000 Nolan was paid for the film) in profit if the “investment “ included all of the miscellaneous expenses I mentioned above (as well as the lawyers cost for acquisition, travel and time spent finding the plot and securing all of the contracts for farming and harvest) and wasn’t absorbed in the “film budget”.

I have own a rift and Q1, 2, and 3 (plus some older, but polished, Cardboard products) but have NOT had a VP demo. The jump from fresnel to pancake lenses - for productivity purposes - is substantial and I expect the VP’s moderately higher resolution to be enough to make the headset actually productive (Q3 is close but still resolution handicapped). I expect the tight integration with OSX to be useful and, if I were (a) on OSX (b) didn’t already work on an 8K monitor and © was a digital nomad or had no dedicated office/room in which to work, I could see a use case for them. Having attempted to work in i(Pad)OS professionally as a remote platform, the standalone capabilities might be useful for a blogger or journalist but is utterly unsuitable for professional work, even less so without a dedicated keyboard and mouse/advanced multitouch track pad. Again, I’ve not used the VP hand-sensing for advance selection* but my expectation is that it is still in its infancy, even with (and perhaos hindered by) eye focus selection.

My hope is that $3500/pop will allow more research, more fine tuning, and advancing to vision limited resolution (Apple is still a factor of 4 short in pixel count, and a factor of 6+ short of my desktop monitor) for future headsets.

* multi-functional, 3D manipulation of, say, finite element model components or full building/industrial models in a program like Revit or multi-assembly models in Blender or Fusion360, where you have 4+ key modifiers plus 3 buttons and two scroll wheels for fine manipulation and hundreds of quick-key commands)

That seems unlikely. It would be hard to imagine that the total costs of planting and raising a movie-set quality corn field with industry labor rates would cost less than the returns on a 500 ac harvest of (I’m presuming) silage-quality corn.

I’m pretty sure that middle bit is like a springform pan. The handle is not solid - you squeeze it to make it sit in the waffle maker but when you remove it, it opens a bit to release. I have no room for this in my kitchen but am intensely intrigued. I might buy a new house so I can get a bigger kitchen and have a place for this.

That puts a smile on my face.

I’m with you. As an engineer, I know a sprinkler works through the transition of potential energy (pressure) to kinetic energy (water jet) and the the law of momentum requires an opposite reaction to the ejected water. For the opposite you would still have the energy of the pump and the momentum of water which must change direction through the flow. OTOH, also as an engineer, I know that there are some effects we ignore or intentionally discount as being insignificant to “real world” applications. Depending on the application, 10% error may be more than close enough, or 0.1% might be. It’s rare that anything beyond the third significant digit affects something an engineer would care about, but physicists deal almost exclusively in those fine differences (having worked with them) and weird things really do happen.

I’ve yet to find a modern use for usenet as I’m not in the habit of downloading everything as it comes out, nor of looking for content within a few days of release. Often I’m looking for 2-5 year old content or back catalog, and usenet has been a uniform landscape of incompletes, even with two blocks on independent providers (or they were when I bought the data blocks).

The best part is that it makes enough for friends to share.
