Why should i buy an ulticontroller??? swapping SDcards all the time is not my thing.. While i'm printing through USB on my UM1 Original, i surely can do a lot more work.. Creating, converting to STL and in Cura to GCode and then instantly printing works a lot faster then putting my work to SDcards... Why not putting the ulticontroller-menu into Cura so all functionality can be used by USB too??? My computer is a multitasking- machine which allows me to use cura, solidworks, internet and a lot of other programs simultaniously... never had a problem with that. The only advantage, as i see it, is that with an ulticontroller you can do prints without turning a computer on, but mine is always on...
