@theruttmeister thanks for the feedback, I tried that already it won’t show up in the UI unless you assign it a extruder drive which just gets messy. Your also right about the UI not allowing for multiples CH’s, when I tired that it confuses the UI and decides to not display anything. An option to add visible thermostats/humidistat like the chamber heater to the UI could open many new options like filament heating/dehumidification, multi-stage heating, chillers, or hepa / exhaust ventilation.
