Hey All - I’ve recently been running into some weird behavior of the IBTS RoR reading and I’m curious if anybody else has run into the issue or can shed some light. Essentially what I’m seeing is that on the first of two back-to-back roasts, the IBTS reading appears very erratic in the early phases of the roast - big IBTS RoR oscillations and smaller IBTS temp oscillations - before calming down in the second half of the roast. On the second of the two back-to-back roasts however, the IBTS appears super stable from get go.
Current thesis is that I am not pre-heating the roaster long enough, but I usually give it a minimum of 20-30 minutes regardless of “charge” indicator.
For some additional context, I’ve only got about 20 roasts on this bullet, excluding the 3 seasoning roasts, and I’ve started seeing this behavior on the last 3 roasting sessions (6 roasts). Here are the screenshots of my two most recent roasts:
