Hi,
I have a question that will probably sound weird, but it has a reason: For quite some time now I've been happily using a diy CoreXY with Duet3D (old one, 0.6.something, but working wonderful as usual). The printer is enclosed on the four sides so it's not really a chamber, but does keep some warmth.

Now I have a problem rather different from standard 3d printing stuff: When baking bread using my own sourdough, I often have to store the dough at some rather controlled and stable temperature, like e.g. 30° or at most 35°C. I could build a chamber for this using some old 3dprinter stuff lying around and putting it into some wooden box, but I just don't have much space for another box at home and would rather do this with my existing equipment.

So I thought about whether it would be possible to use the hotend thermistor (with a turned off hotend of course) to check for the temperature in the upper part of my printing chamber, while regulating heat with the heatbed. Up to now I can only see how to regulate the heatbed by heatbed thermistor, the hotend by hotend thermistor. I do see this might be considered an unorthodox usage of a 3D printer, but it would definitely help me and my family with certain daily needs My printer is big enough to store the bowl for the dough. Turning on the layer cooling fans on a slow rate (which wouldn't hurt the sourdough, as it's covered by cloth) would help to spread temperature evenly.

Would this be possible to do? I do understand bakery is not exactly your prime concern with Duet3D, but you've made me very happy with Duet3D already, and here would be another great appliance!

Thanks a lot

Ah, great, I overlooked that X parameter, that seems to be exactly what I need. Thanks a lot!

Thanks a lot! I read that (on configuring a chamber heater) and as far as I get it, I could configure a chamber heater with the heater number of my heatbed -- but wouldn't it then read the temperature from the heatbed thermistor as well?

My hope was that (by g-code or patching firmware, without modifying my printer, which I still use for 3d printing of course) I could somehow use the heater output for my heatbed together with the temperature readings of my hotend (which, the printer being a CoreXY, is always somewhere at the top, where I'd actually want to measure my air temperature).

I hope I got my idea across -- thanks again for your tips!
