  • 5 days seems pretty reasonable to design and build most stuff. It’s function and system/integrated test that takes time not to say there’s not random bits of work that take months before anything testable can be produced.

    *My experience is in giant systems processing mainframe class data. The programmers in my team use COBOL







  • You obviously need to ID the spools and store values for all, the different hub weights aren’t a big issue if the printer knows the length of its filament path, how much filament the spool started with, and how much filament has been consumed it can work out the hub weight

    Regularly changing filament fixes the problem of the load cell drifting, by allowing it to zero occasionally

    You could warn on low filament, or not enough for this print, but load cells aren’t accurate enough to be certain about the last few metres, along with errors from cosmetic trimmed before feeding, or some is damaged and cut off, so I would still use the normal no filament sensors for stopping

    Not saying it’s worth it compared to a software solution in the slicer




  • Technology Connections in his recent video (or was it on his second channel?) points or that since dishwashers had only six functions, all of which run when given line voltage, and case running when depowered, anyone with Arduino and some relays could make a new control board for a dishwasher pretty easily, to make programs that way better. Laundry machines are similar but simpler, if they ever get that bad, they’ll be easy to lobotomise
