finally!!

Hey guys!! Just finished roasting  today and am excited to say that I am kinda getting the hang of this thing!!!  Just so excited about having good coffee made by myself so just thought I'd share that with you! Happy roasting!!

Let us know how it tastes

[kctremel]

It tasted alright, did a roast yesterday that turned out much better.  Definitely getting better but still need some work.

The curves are looking pretty dang good! Are you roasting for espresso?

[Gregr]

Great roasts, especially considering how new your roaster is.
It looks like you're getting a bit of a 'flick' there just at the end of first crack. That might get you some undesirable roast notes (maybe). Here's the article on the flick that brought it to our attention:

Adondo - I am roasting for brew. Thanks

Gregr - Thanks for that article. I am having trouble with that.  Did roast yesterday where I almost got rid of it completely but then I messed up a little by adding too much fan and manually flicking myself on accident.  Thanks once again guys.

[Gregr]

You gotta watch out for that self flicking 
What's working for me is to raise the heat to 1.5-2 kPa right when first crack starts, then back it off to 1.0 about 30 seconds later, then lower it again to .5 kPa when first crack is over, then turn the stove off completely about 15-30 seconds later and coast to whatever amount of development I want, watching to make sure the bean temp delta doesn't drop below about 3-4F/min.
The fan is at 25% all the way thru first crack and then I raise it to about 75% when first crack is over, then to 100% when I turn the stove off. With the fan full on and the heat off the temp will drop very quickly- no chance for a flick at all.
Since our approach on the earlier parts of the roast is going to be different you'll have to figure out heat and fan settings that work for you but that gives you an idea of what can be done to help with the flick. Example attached.

That first sentence got me good Greg, haha.  Once again thank you, you've been more than helpful to me on this whole process and I am forever grateful.  Thanks for the tip.

newest and best one yet.

[Gregr]

I look forward to hearing how it tastes
By the way- it looks like you have the BT and ET probes backwards on the graph.

@Gregr

I am looking to add power and fan notations to my graphs as well, so I was curious about yours on post #14416.  Can you explain how to read the power notations?  What scale they match up with?

how do you mean? The center 304 I have the BT probe in as #1 and it shows the blue line as that.

[Gregr]

First the easy one from kc- the ET is higher than the bean temp for pretty much the whole roast and your graph shows the opposite. It's very common and I don't know if Artisan is to blame but it's an easy fix. You can invert them in the software or just swap inputs on the Center.
The scales for fan and power (set up on the buttons tab) are estimates. For the fan I use a Speedster dimmer that has a scale around the knob- 0 to 100 easy peasy. The power is based on the Dwyer gauge I have. It maxes out at 4kPa so 4 is 100%, 1kPa is 25%.

[kctremel]

Greg, you're not talking about the delta values are you? The red line is my ET and is above my blue line BT the whole roast until the end but the delta ET is lower than my delta BT showing me my RoR. IDK if it's suppose to be like that or not, I just wanna make sure that I am doing it right and not messing up and going completely the wrong direction.
Thanks, Kyle.

[Gregr]

Yeah deltas- sorry that wasn't clearer.
