  • My Prusa XL 5 tool is printing like a champ. So far I have printed a 2 colour PLA print that took the whole print bed and a flexible (TPU) print for my bike

    It hasn’t missed a trick

    I love Prusa

    I also have an ankermake printer which I bought hoping their colour system would happen, but it never did. I’m tempted to replace it with a Prusa mk4s with their working multiple material unit (MMU) which is already in version 3

    And it works with an open source slicer

    And their printers have a history of being upgradable

    Any printer I get in the future will be a Prusa




  • 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












  • Indeed, but cheaper than enough batteries to cover those times

    In the off grid home scale one I’d size and set the generator to run for several hours in a row to fully charge the battery on days when the battery was at a sufficiently low charge entering the night, at least that’s what my current modelling suggests. Diesel gensets work best when running fully loaded for at least long enough to warm up

    I guess at grid scale you find the sweet spot where most years the gas power station and batteries are balanced to provide cheapest power averaged over the year
