I've been using the Artisan program for some time now on an Ambex ym2 with
an Omega data logger and a 2 ghz dual core laptop. I just loaded 0.8 and
I'm hoping that I might get smoother ROR values with this version as I see
that is one of the improvements. Maybe the issue is the fast response of my
probes? Is there a way to compensate for this in Artisan? Can you make
some recommendations as to the EXTRA settings for the newer version and
maybe something up to date about the effects of using values too large or
too small? My ROR just jumps around too much and by the time it's
dropping/rising too rapidly it's almost too late for me to do anything about
it. Could I benefit (or not and why) from using over sampling or a higher
or lower sample rate? I'm at 4.0 now. Which curve smoothing values affect
real time displays and which don't? I've been reading Scott Rao's new book
and find myself evaluating my roasts and looking carefully at ROR and 1st to
drop percentages so Artisan is so useful. Thanks so much to all that have
contributed to this great program.
I've just started using 0.9.0,and have noticed several bugs in the display.
1) if the background profile is adjusted in background properties, the
event labels sometimes get left behind in their original position.
2) The roast title suffers the same fate, and can disappear off the screen.
3) Alarm popups are no longer in the centre of the display, but off to one
side. Could also be a symptom of moving background profile.
4) The screen 'flashes' all white every now and again, as if something is
being updated and the display is completely redrawn.
I prefer the stability of the previous version, but the ndw functionality
is very nice. Thanks for all the hard work!

I would need to look into visualizing those, but there’s very little jumping around here. I have a 1 second sampling interval.

I get my probes from http://www.tcdirect.nl — they have branches in many countries. Lots of affordable probes to choose from. It’s important to select one that is sensitive but not “grounded” so it does not touch the outside metal skin. You want it to be sensitive to the bean mass, but not to jump the temp reading every time a hot bean hits it a little harder. Like feeling with your finger tips, it helps if your skin is not hard and thick but it hurts when you take off the skin and then play the piano ;-)

yes, but without the first ’n’ as in Fracino ;-)

A fun thing!

You could also leave out the Deltas as it looks like lots of noise cluttering your ‘roast intel’ there.
I had ET but since it followed BT on a constant distance I left out that probe again.

That sounds like a good plan!
On our small roasters we can do things faster.

I have experimented much and like making coffee first it’s more or less blindfolded feeling around for something that might work, then tweaking marginally and seeing, a week later, if it improved the taste. I do measure the roast color immediately after cooling down and this tells me something already. Also I bite a bean or two and if they are too hard still or they pulverize then I know I did not roast enough o I destroyed the beans over-roasting.
Try (after First Crack) right-clicking on the FCs field / LCD window in the top, left of the <RESET> button!
