@jay_s_uk So, everything above 100000Ω I guess? Anyway, thanks for the quick answer.

RE: Cheap way to add 1 Thermistor
@dougal1957 I am currently using 3 Tools, 1 Bed heater and 3 separate chamber heaters (silicone mat). So, there are 7 and the one I want to add is for chamber monitoring.
How accurate are two silicone heater mats if I connect them together in series? Are there any problems with bigger temp overshoots or is this a usable solution?
@Nurgelrot I think that would be a bit overkill -
RE: Cheap way to add 1 Thermistor
@jay_s_uk Changing the Hotends would be not very cheap because I’m using the slice copperhead with the HT sensor and it would be a really big pain in the butt to change them too. Same with the Keenovo bed heater. The Sammy-C21 is a bit to difficult for me to deal with. My last option was the extension board with a different sensor but I don’t really like them but it seems like my only option.

RE: Cheap way to add 1 Thermistor
@jay_s_uk thanks for the quick answer. The range i want to measure is between 20 and 120°C (chamber Temperature).

Cheap way to add 1 Thermistor
Hi I want to add 1 extra Thermistor to my Duet 6HC as cheap as possible. Is there something like the PT100 Daughter Board for Thermistors? All my Temperature inputs on the 6HC and on the 3HC Expansion Board are already in use. I thought i saw someone with a Daughter Board for Thermistors a few days ago but I can’t find the site anymore.

RE: Heated chamber air circulation fan
@diy-o-sphere all the cheap ones are loud but the bigger problem is that there is no space for one. under the chamber is a filament drawer so its not possible to mount something down there. i cant put something in the top part because of the motion system. so the only place left is at the back between the side panel and the cabel cover (95mm)

RE: Heated chamber air circulation fan
@phaedrux the rotor itself is currently 16,54 Grams and the inertia is at 86,87 gcm². the shaft will be as small as possible and so not really heavy. cannibalize of some random fan would be possible but I don’t have one on hand and i would rather by a separate motor (less getto style)

RE: Heated chamber air circulation fan
@phaedrux it's quite nice and not too expensive for its properties

RE: Heated chamber air circulation fan
@phaedrux the fan itself sits in the chamber and is connected to the motor by a shaft through the chamber. same principle as an oven fan

RE: Heated chamber air circulation fan
@phaedrux The Mechanical design is not my problem. But the selection of the electronic component is. I Don’t have a problem putting an oven fan in the chamber but controlling it would kill my knowledge because I don’t even have a clew how to control such a motor or if it’s even possible to do so. My favourite solution would be a simple fan motor outside the chamber but I don’t know witch motor I should use and how I should control it. I just want the fan to be quiet (1k rpm) and easy to use so I can control it via the slicer. Is it necessary to design a radial fan from the ground up with a part cooling in mind? No decently not but I like to learn as much as possible while building this printer and that’s why there is so much “overcomplicated” stuff like the hydraulic tool changer inside. I just need someone to guide me a bit in the right direction.
@rjenkinsgb Yes everything inside this Printer was selected with the Temperature of 120°C in mind (HT- cables, Stepper and Hotend are watercooled etc.). The position of the inlet isn't ideal but it should works good enough and if I put the whole thing upside down I wouldn't have a chance to use the fan in the future as a "part cooler" as well
