Hello, My UM3 has been acting very strangely, and I can't get a print going as a result. The UM3 will spontaneously tell me that a print core is missing, when said print core was never changed out. This causes significant issues because the print core has filament connected to it, and the UM3 will try to force me to put in a print core when one is already In place and can't be removed. Additionally, the UM3 will freeze when warming up or cooling down, showing no progress on the bars, even after ten minutes or so.
