This morning, I did another roast trying to emulate your most recent instructions. It seemed that at a Heat Setting of 5 with the fan on the first notch, it was not moving closer to 1st crack as fast as it should.
The great part about this machine is that one can adjust all parameters "on the fly." I lengthened my initial time setting of 20 minutes, and upped the heat in increments until I could sense that 1st crack would come soon. It did, and I ejected just before 2nd crack and the dial read 413 F. The beans look pretty good.
As far as the Omega temperature probe is concerned, I attempted to purchase one at the place where you got yours. However, when I got to the cart it showed as "out of stock." I e-mailed them last week asking when and if they expected more Omega probes to be in stock. So far, they have yet to respond.
Hopefully, they will eventually do so which will spare me from "biting the bullet" and going to one of the more expensive dealers.
As of now, I have 27 roasts on the machine. What is your take on when and how often to change filters?
Thanks again
