  • Afaik the firmware is self developed and closed source, so not free. as in freedom of code and free as in beer.

    The software slicer is based on prusa slicer which is based on slic3r which uses the agplv3 which dictates that all works derived from the original code needs to be published as code under the same license. They do that. But the trick is that they add closed source modules that are essential for the whole system to work and therefore control their devices and ecosystem via restrictive licenses or plain unavailability of sources.

    Regarding creality : the last time I used a creality printer it used marlin as firmware and it was trivial to compile and flash and modify.

    But in general you don’t need to make your product easy to jailbreak under most ooensource licenses, you need to publish the code. Those are two different things.







  • Oof you are very sure of yourself.

    Regarding the asphalt: If there is a delta in energy level in matter then it will even our until an equilibrium is reached.

    How could this apply here? When a car tire rolls over the fresh asphalt it wouldn’t rest a long time in one spot but it would definitely absorb some energy during contact. Since it is rotating and contacting the road it is reasonable to assume that there is would be a decent amount of heat transfer. Wind or air cooling of the tire doesn’t seem like a significant factor here. But that doesn’t really matter here anyways.

    A long stretch of hot asphalt gives us a equally long distance of a tire surface area contacting the ground.

    This gives us some heat transfer from the road into the tires.

    The car drives in and takes the heat with it.

    Many cars equals a decent amount of heat.

    That could explain the pattern.

    It is smart to think about alternatives to your own opinion when you don’t know all the facts.

    Did I think about it very hard enough?
