Hi
Sorry, it's the new pt100 temperature sensor...'E3D V6 PT100 Total Upgrade Kit' from E3D-online. I am trying to install an e3dv6 hot end on the UM2 clone i'm building, and the um2 mainboard gives me a 'TEMP SENSOR ERROR message when I power it up. The kit comes with an amplifier board which is supposed to be connected to a 'spare analog input pin' on the mainboard. I have no idea how to change the firmware to enable it, although I think I have coneected it to the right pin selected
The um2 clone is an aluminium extrusion version...it has the white mainboard plus ultiLCD
