I updated to firmware 1.10.0 and quickly ran into an issue around the hot end temperature, upon restart of the A350. I can either print Aluminium or there is a serious fault
Turns out I couldn’t do anything, the screen froze when I tried to Home the device.
I downgraded the firmware to 1.9.0 and reset device configuration. This seemed to at least let me control the A350. I tried to start a print and it looked like it was going okay. However, once it reached 200/200 and just before it started the print the display jumped to 251/200 and then froze and the device became unresponsive.
Perhaps it is a problem with the hot end kit? I replaced it with the spare one.
Restarted the device and tried another print, the print was successful.
Tried another print, it was looking okay and then suddenly the temperature jumped to a reading of 341C and the device became unresponsive.
I double-checked the wire connections between the hot end and the print module. One of the pins in the connector was loose. I tried pushing it back in but the connectors are pretty flimsy.
This feels like either the connector needs replaced or there is a bigger Extruder Module issue going on?
The connector in question being the one from the PCB board that is exposed under the Extruder Module that you plug the Hot End Kit into.
