I tried to calibrate my fan, and after doing so, the fan speeds are pretty much all the same, no matter what setting I have it on. My uncalibrated settings are much different than what’s shown in the user menu for the calibrated settings, and I experienced the A-08 error a few times during cool down when doing back to back roasts, so that’s why I figured I should do the calibration.
Since the calibration didn’t work after trying it a few times, I updated the firmware to the Beta 602 to see if that would help. I tried calibrating again, (this time the Bullet throws the ErC 6864 when it ends, even though, as near as I can tell, the IBTS fan is working correctly), and the same result happens: there is very little difference between the blower fan speeds. I think it’s about 60 - 80 rpm difference between F1 - F9. Uncalibrated is the same as it was, very large RPM differences between the fan settings (about 3k rpm or so from F1 - F9).
Anyone else experience and solve this?
