  • From what I’ve seen, middle of the road 300 mm Voron V2.4 kits are around $1300. I believe the lowest I’ve seen was around $950, excluding printed parts (which the same company was selling separately for over $200). When I tried compiling a BOM with self-sourced high quality parts, the total reached over $1700 before I gave up on that idea. Where have you seen $600 kits? If these are still available, I may consider one. However, I’m hesitant to go with a kit that may have lower quality components. Personally, I’m really excited for this new Prusa and will probably pick up a kit once they are available. Unless, of course, Vorons are really that affordable.



  • This is not their first core XY and they redesigned the hotend with the PrusaXL and MK4. As far as I’ve seen, they are the only printer company using a strain gauge in the hotend for bed leveling, that they also use for detecting clogs while printing. Also, the new printer’s price is comparible to the similar model from Bambu with a metal frame and enclosed print bed (X1C). And, as you pointed out, they always maintained the same serviceability (I’ll add upgradability). Therefore, I definitely don’t agree that they are playing catch up.



  • From your source:

    {The upper flow is faster and from Bernoulli’s equation the pressure is lower. The difference in pressure across the airfoil produces the lift.} As we have seen in Experiment #1, this part of the theory is correct.

    Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn’t diminish the effects of this pressure differential on lifting force.


  • That lift explanation is innacurate/incomplete. While there may be some equal and opposite forces depending on the angle of attack, the primary reason for lift is due to Bernoulli’s Principle. Airfoils have a rounded upper surface with a longer path for air to take, relative to the underside. This requires air to move at a higher velocity over the top, and since A1 x V1 x P1 = A2 x V2 x P2, pressure over the airfoil decreases. It is this pressure differential that creates lift.

    In regards to aircraft, Newton’s third law of motion applies to thrust from a propeller or jet engine.



  • I must say I don’t like the idea of a social-credit-score bot.

    Regarding your implementation, I saw the summary of your own comments elsewhere in this post and I noticed all the annotations were on upvoted/blue segments. Other summaries you posted focused more on negative/red segments. Would it be possible to enforce a minimum of 1 or 2 from both categories?

    Also, would you be kind enough to read my tea leaves? Am I an acceptable citizen of the Lemmy community?


  • I always prefer to sit unless I’m in a huge hurry. It’s called a restroom for a reason. I’m going to take a break, browse Lemmy or something, and otherwise “rest”. I’ll return to work when I’m ready.

    What really pisses me off is when I hear someone enter another stall to take a standing piss. They rarely put the seat up and always get pee all over everything. If you’re going to stand, use a urinal. There’s nothing more pathetic than being afraid to whip your dick out beside your fellow man, and instead, choose to piss on the place where others want to take a sit.







  • How long does MG consider to be a lifetime? I’m daily driving a 32 year old car.

    Edit: Ok, I looked it up. It’s an unlimited-mile warranty for the first 12 months. After that, it lasts up to 80,000 miles or 7 years, whichever comes first. This is less than the battery warranty for many other brands. This kind of advertising should be illegal, but they placed “lifetime” in quotes, so I guess everyone’s cool with it. Actually, it looks like that might be the old warranty, effective in 2019. I’m having trouble finding the actual terms for the new warranty, but I wanted to correct myself first.
