Monitoring water temp with virtual heater/tool



  • I want to monitor the temperature of my water cooling loop. I added a 10K thermistor (sadly with an unknown B value) and configured it using virtual heater 103. It shows up in the extra tab on DWC and in the graph if so chosen.

    M305 S"Water" P103 X2 T10000 B3950
    

    Since the temperature variations are in in the same order of magnitude as the bed or hotend heater, the graph does't really suit my needs. Therefore, I wanted to configure an extra tool just to numerically display the temperature. I guessing I do not fully understand how to configure this, as it does not give the result I expected. Any nudges in the right direction are welcome 🙂

    M563 P1 S"Water" H2

    You can either configure the thermistor as a virtual heater using the M305 line you quoted, or configure it as a real heater using:

    M305 H1 P1 T10000 B3950

    and then configure a tool to use it as you did with M563.

    I assume that has to be a P instead of an H, the wiki tells me the H parameter deals with ADC offsets.

    UPDATE apart from the parameter thing, it seems to work now, thanks.
