Try to lower the Maximum Environment Temperature to 260 / 270 C. However it seems a bit too low, the roasting time extended to 19min.

Here's the wiring diagram of my PID modification. This is for reference only.

Very nice!!
I understand why you are using two PID now.
BTW how much is a Fuji PRX4?

Hi are you also using Quest M3?
I've got one last week. It's a VERY good and compact roaster. ??manual mode嚟????feel

In fact, Alex and I are doing some research to use TC4 Arduino shield (I've one on hand now) as data logger to directly connect to PC with USB (later maybe able to wirelessly use Bluetooth or WiFi), while TC4 is also capable to control SSR and act as a PID with the use of a program called aKona.

If more ppl use M3, there will be more fun for sure. We can also share our roast profile/1C temp/2C temp info etc for particular green beans.

Thx, I got my PXR4 from Taobao, PXR4 without RS485 is around CNY350, PXR4 with RS485 is around CNY750. Make sure the model number is right, there are many different options (unit C/F, SSR, Normal Relay, ....)

I use PID mainly for data logging and control of the MET (Maximum Environment Temperature).

Alternatively, Arduino with coffee roasting module (TC-4 support 4 thermocouple) is another less expensive but powerful option to consider as mentioned by Peter. If I do it again, I will centainly use Arduino.

Also the Artisan Roast software (freeware) is quite useful.

Alex, my TC4 Arduino shield is working properly with Artisan now!
Next step is to get aKona and pKona working as PID. From their documentation , except normal PID functionality, it seems you can also control the ROR (rate of rise) of target temperature etc as part of the profiling, which may not be readily adjustable with the Fuji PID, no?

I'm also thinking about modifying my espresso machine to accommodate the TC4 as temperature controller (just add a switch like your M3 and a thermocouple will do). Adding a bluetooth module to the Arduino can let the mobile phone controlling the TC4 and as a results the brewing temperature. Sounds very interesting to me.

Nice graphs. I think the logging of Delta-ET and BT of Artisan is a bit uneven. I am not sure if it is the sampling frequency or the logic.

I usually drop bean before the start of SC or near the end of FC. Would your 1st roast be a bit too dark? In your 2nd roast, I think you have tried to stretch the FC by reducing the power hence reducing the ROR. How's the taste of these 2 roasts?

BTW, I found the charge temperature can be higher say at 180C or 190C without scorching for bean mass of 150g or 200g.

Just tried to maintain a straight-line roast for Sidamo Natural.
