Help: Upgraded TinkerGnome firmware, now I get X or Y switch broken in Ultimaker 3D printers Posted September 1, 2016 Hi @Tinkergnome. Thanks for responding. I see. So, to upgrade I need a factory reset. Sad Panda! :( Out of curiosity, do you think that if I downgraded to an earlier stock version before the address changes, then put in the old Tinker 16.07 that I could get back to what I had before? It was working fine for me. I probably would not stay that way, stuck in time as it were, but I am just curious if you think I could go back in time by downgrading. Thanks very much. And thanks for your firmware! I really like it!
