Just waiting on my TC4 shipment then it's roasting time

I rarely purchase roasted coffee. I just ordered 4 bags from Mountain Air Roaster.

Hi, I use a wok with a glass lid for roasting. shaking the wok is a good exercise, actually.

TC4 with aArtisanQ_PID
Ramezaziz
I changed it to 60HZ, but the heater is barely heating, and the fan works but weak, should be there any other reason? Thx.
 
greencardigan
I'm not sure what the problem is now.

Are the heather and fan definitely working properly when sending the commands from the Arduino terminal?
 
Ramezaziz
Yes they are, maybe at night the voltage goes down, should I use 65 HZ rather than 60, or that may cause problems?!
 
greencardigan
You need to use 50Hz or 60Hz. Where are you located?
 
greencardigan
US is 60Hz
 
Ramezaziz
I am in the US, I used the 60 HZ, but the heater barely works and the fan is much weaker than working with the Arduino, is there a reason, does yours work like this? Thx.
 
greencardigan
No, it should work the same when controlled from Artisan.

There are two things I suggest you try.

1. Make sure you have Artisan set up correctly.

2. You could try going back to the original version of aArtisanQ_PID. Version 4_3 I think. I'll attach it.

.
greencardigan attached the following file:

Could there be anything in the user.h for the aArtisan sketch that needs to be checked?

I am not really sure, I am not a computer programmer.
I can't get the heater back to work again, maybe that happened after I went back to the old Artisan file, not sure, please advise.

Thanks!
 
greencardigan
There's really only some minor differences between the two versions. Nothing that should make the heater not work.

Do you have the ANALOGUE1 and ANALOGUE2 lines commented out in the user.h file like this //#define ANALOGUE1?

Also can you try commenting out the #define PID_CONTROL line in user.h.
 
greencardigan
I have just tested aArtisanQ_PID version 4_3 with Artisan 0.9.2 and it was working fine. I didn't make any changes at all to the user.h file.

This was compiling with Arduino 1.0.6.

Can you provide some details regarding how you have Artisan set up? Are you using the heater and fan sliders on the left or some buttons set up to send commands?
 
Ramezaziz
You guys are so great, IT IS WORKING FINALLY!!! MANY THANKS TO YOU.

I am just not sure where to get roasting profile like for Jamaican blue mountain, etc. do I have to enter the codes manually or there are files where I can download from online? I am only able to control the heater and the fan through the sliders and the buttons that I created, but not sure how to load profiles.
What does the SV slider does?
Where can I download alarm files?
Do I have to upload special sketches to the TC4C board or I can still upload roasting profiles and share with other coffee lovers? Please advise.

Thanks!
 
greencardigan
Excellent! What was the issue?

aArtisanQ_PID does not currently support the PID SV features in Artisan. Only the base aArtisan currently supports this new feature. I hope to add it to aArtisanQ_PID sometime. Alternatively, Jim may update aArtisan to incorporate phase control.

The SV slider sends temperature commands to the TC4 and the TC4 would use the PID to follow the temperature (SV) sent from Artisan. But as I mentioned, aArtisanQ_PID does not currently support this.

You can still load profiles into the background of Artisan and use the heater and fan commands to follow the profile.

Also you can save your recorded profiles to share with others.
 
Ramezaziz
The issue was that when I created the buttons, for a reason the serial command was not selected only was selected on the fan @25%, I am using the most recent updated files that you gave me with the libraries, thank you!

How can I load profiles into the background of Artisan and use the heater & fan commands to follow the profile?

Is there a link for profiles or forums to share them?

If I configure the cup profile in the software will that create automatic profiles, if that is the case how to do it, not sure how does that work?!

I really didn't assemble the unit yet, do you think if I squeeze the TC4C board inside the Poppery I with the two Crydom SSRs with and adhesive heat insulators, that may overheat the unit, I really want it to look good, but safe at the same time, or that may fry the TC4C board? Please advise.

Thanks once more!
 
greencardigan
I'm not familiar with the Poppery so can't comment regarding that.

To load a background profile in Artisan, go to the Roast menu and select Background then click the load button.

Once you start the roast you can use the heater and/or fan sliders to manually follow the background profile.

I'm unaware of any places with profiles to download.

Setting the cup profile has nothing to do with creating roast profiles I don't think.

One option that is available with the aArtisanQ_PID sketch is having roast profiles stored on the TC4C's eeprom. There are some instructions earlier in this thread for doing that and activating the PID. This lets the TC4C automatically adjust the heater to follow the stored profile.
 
Ramezaziz
Thank you so much, you are such a great help & respectful person. I wish I can return back the favor. Have you tried green coffee beans soaked in aged rum? I can share with you my receipies if you are interested.

Thanks once more!

Ramez.

I've released version 5_0 of aArtisanQ_PID. There's not many changes. Most were keeping it up to date with my TC4 Android App.

This version currently supports most features in Artisan, Roastlogger, and my Android App.

Download from the TC4 Repository here.

Ramezaziz
Thank you!
 
Ramezaziz
I am not really sure if I load a roasting profile in the background, shouldn't the fan and heater start or I have to start it manual using the sliders or the preset buttons to have the fan at 100% & the heater at 50% or 70%? shouldn't the profile take care of this?! And if I change the heater to 75%, wouldn't that change the roasting profile? Or I am doing something wrong?

Thanks!
 
greencardigan
The automatic following of roast profiles loaded into the background of Artisan is not currently supported in my code (yet). So at this stage Artisan will not be able to automatically change your heater. You have to do it manually with the slider.

I hope to add support for Artisan automatically controlling the heater soon.
