Ideally you want the chamber temp as warm as possible. This is how I “preheat” the chamber.
- Turn the bed on full (100-120c depending if you have 220/110v)
- Home the machine (to bring the bed to the top)
- Turn on the aux fan so it will blow across the top of the hot bed.
This will get you a chamber temp or 45-50ish in about 10-15 minutes.
