If it worked well initially, it is extremely unlikely that you need to re-calibrate.Aloha,
Reporting back after first 10 days of TM2.
Initially I was very happy on my unit, producing lots of vapour. About after 1 battery cycle, the vapour started to drop until now it is less than my OG Mighty.
I have fiddled with oven size, bowl load, starting temperature, draw speed and tried al possible combo's of CU and rimless screen.
I only notice to get more vapour when I pull very hard. This makes me think I have a leak somewhere. Abv turns browns slowly. I reinstalled all loose parts ( metal tube, o-rings, both screw on tops,... to no avail.
I also tried 3 other new (moli)cells.
And only once I got huge clouds at setting 5. The herbs is the same batch since the first day I have my unit.
Should I consider calibrating? Other advice or parameters I might need to tune in?
I have read the 60 last pages here and looked on Reddit too before posting.
I quit combustion finally and I need my TM2 to work (better).
There seems to be two primary causes of reduced vapor: an air leak caused by a missing o-ring or a dirty battery contact at some point. Given you've only had the device 10 days, unless you did something that might make the battery contacts dirty, it seems unlikely that would be the cause so quickly. So I think your assessment of a leak is probably correct, and you should check all of the o-rings to make sure they are sealing.
