Help understanding Max Chamber Temperature
Hi all,
Completed my build a few days ago, and I've done a handful of successful prints. I'm a first time printer, and I'm just now paying attention to the temperature values on the LCD screen. One thing curious to me is the chamber temperature. It seems to have a max default of 20C, but is flashing blue with a reading of 32C.
- I'm printing PLA
- Live in Florida
- Entire family (except me) likes the house temp "mild", so the ambient temp is 26C (77F). Nothing I can really do about this
- LCD Menu (I've changed nothing here):
- max chamber temperature = 20c (default)
- print fan speed = 98%
- chamber fans = auto
- chamber fans limit = 40%
So far, I'm not noticing anything that seems "wrong". I'm just printing what I consider simple things like hooks and sponge holders. But I'm curious if this is indicative of a problem, or do I need to adjust some settings, or is sometimes normal?
Uploaded a pic for clarity.
Thanks!
RE:
Nothing is wrong. The reason the chamber is 6 degrees above ambient is because the heat bed and hot end are heating up the chamber. For the filament types that require a heated chamber, the heat bed temp is increased to 110C which acts as a surrogate chamber heater.
For PLA, it's sometimes necessary to also (besides opening the top vent) leave the door open.
