I just installed for the first time a brand new CC 0.6 red i had bought a few months ago. The printer reports it as CC with no size suffix. There is no option for a print core CC within Cura only CC 06 and CC04. I chose CC06 but the printer complains about a mismatched configuration. Forcing an override causes the printer to complain that the head as timeout before reaching temperature. This is in fact not true as the error is issued while the temperature of the nozzle is already 260C which is the target value. I suspect that the head is 1) faulty or 2) no longer supported by the firmware (7.0.1). Has anyone else experience this issue? Any suggestions as to what to try? Thanks Alejandro
