    I'm trying to set up my BogBox as a dual. I have a older-style v6 hotend with thermistor that I've installed as a second hotend.

    However, once it's setup in Marlin, the reported temperature doesn't seem to be affected by the resistance on the Rumba thermistor1 or thermistor 2 wiring.

    Even more strangely, the reported temperature on the second hotend changes based on the PT100 reading on the first hotend - inversely!! See below.

    Any ideas what's going on and how to fix it?

    I think I have the fix for this.. changing RUMBA_pins.h back to the main Marlin branch. And undoing the BigBox edits for a PT100.

    Code:
    #define TEMP_1_PIN       14
