Insulating the cabinet

[torch]

No problems at all with the insulation. The chamber heater, on the other hand…

I started a thread on the chamber heater here:

MAX chamber heater poor design

The heater itself is fine, but the darn thing draws room air in, forcing heated air out of the exhaust fan opening. What a waste! It heats the room as much as the chamber. It needs to heat the air in the cabinet, NOT the room. I designed some printable duct work to draw the air from the bottom of the chamber (where it is coolest) and recirculate the warmed air. Used with DKEU’s heater config, it dramatically reduces the time required to reach the desired temp and dramatically reduces the amount…

Basically, the gist of it is the chamber heater does more heating of the room than of the chamber. I designed and printed some ductwork to keep the heated air inside the chamber.
