  • is it so much more expensive than manufacturing a HMD 2660, which does more or less the same things and retails for approx. $100?

    Yes, extremely so.

    HMD will manufacture millions of them with partners they have been using for a decade, they will each skim a few dollars to cover costs and profit and still do fine.
    Commodore will manufacture a fraction of that volume using parts way more expensive as they buy less of them, and they still have to cover r&d and tooling costs from that lower volume.

    That is why kickstarters (and pre-orders) are so damn useful, as that allows you to get a start at covering those costs before you even manufacture anything.








  • A lot of wealth is based on perceived/theoretical value. Most of it, in fact. Let’s say you own a car or a house, their value is based on what someone else is willing to pay for them, but you can’t know how much that would be before you do. Heck, even bank notes are technically just “worthless” IOU’s backed by a government.
    That doesn’t mean your net worth is zero just because you don’t have cash on hand.

    Shares are (in reasonable sale quantities) more factual, because they are essentially based on buy offers: if you have one SpaceX share, you know it’s currently worth exactly $160.13, because someone has offered to buy it for that amount.

    And this is entirely ignoring the fact that you, like Musk, can turn the “perceived” value into “real” value extremely easily - it’s called a loan. Musk got a cool $13 billion one back when he bought Twitter.










  • Yes, even when the sensor fails.
    If the feedback from the thermistor is either nonsense or doesn’t change as expected even when the heater is on/off for a certain time, that should trigger a thermal runaway error and halt the printer. That’s basic decade plus old Marlin code.

    I’ve had two broken thermistors in my Ender 3. First one reported negative temperatures when it disconnected, so the printer immediately halted with a min temp error. The second reported something like 150C, which was in the acceptable range, except when it tried to heat it up and nothing changed for like 15 seconds, which triggered a halt.
    Again, decade old marlin code. Not rocket surgery.
