Chamber heater from Creality, make it simple  

Chamber heater from Creality, make it simple

Heres my quick fix to solving the veeery long heat up times in my 7 degree cold garage. I chose the heater since it was completely standalone, and I didnt want to DIY anything this time. I thought it could reset its settings after a power off, but sadly that was not the case, just some lost in translation, so I cant remotely start it up, which is a drawback. But it really does heat the chamber up quickly, the difference a separat heater makes is BIG, especially this size. I thought about putting it from the side panel, but this was simpler so I thought it was worth a shot, and when its heating up with the bed at the top this is significant faster since i dont have to heat up all the 20kg of steel below the bed area. Which normally during printing stays quite cold due to the sealed of nature of the chamber design.

Making a chamber heater to run 80 degrees chamber temp would be very different solution, but for this use case it works well as it sits. I probed around this printed quite a bit with a thermocouple, before and after mods, so I have a decent feeling of what it does, and pretty happy so far with what how it works, even with the bed all the way down. The warmer the bed and chamber gets the less work the heater does so if you keep it on during a print it runs colder than i anticipated. Might try 58-60 for some really large prints, its almost there during summer anyway, so I dont think it will hurt anything. Testing will continue, especially later this winter when i might try maxing the print volume with some car areo parts, which often can be challenging with higher temp materials.
