  • Precision movement is definitely solved, but rapid precision movement required for fast printing isnt easy, and requires tuning.

    The legal requirements likely only apply to commercially sold and operated printers. Patents really only matter once you are making significant money, HP et al. aren’t going to give a shit about diy efforts. Not a lawyer though.

    The real issue is that printers are already dirt cheap (and despite some complaining here and there, work really well). Its hard to convince people to invest hundred to thousands of dollars to diy build a printer when you can buy one from an office supply chain for $50 (its wasteful, because it’ll only last a year, but it makes financial sense). Even diy 3d printing is basically dieing out with people preferring to buy an off-the-shelf system.













  • Really depends on if it has a proper internal USB hub or not.

    And with a non-PD charger its perfectly safe.

    But very good point, that you do need to be careful. Especially with Aliexpress junk.

    Edit: tested mine, which is a Y cord thing, like the first link, and it does not pass more than 5v to the audio side. So it really depends what you get. You can’t power it from the audio side either, so there must be some kind of proper isolation.
