I agree with the above, I am sure it could be done with a usb network card and the memory card in the sd-reader as storage. The bord in the machine should be capable to handle the rest. This way all the old UM2+ could still work and get support for firmware upgrade network printing etc. I have tried octaprint and don't fell i get the same result when printing, might be a bad config on my part but as this now is part of other printers. I am sure you already have 90% of the software in place and I would pay for the upgrade to not have to bother with a second device and a solid experience.
Tout est dit, fiabilité & fiabilité de l'imprimante.
Mais le rendu de l'impression n'est il pas dû également avec le logiciel de découpe. En meme temps que je m'informe sur les imprimantes, certains parlent de simplify 3D moi perso j'utilise Cura
