1 lb roasted lasts a week. I can taste the flavor increase to peak, then drop after. Still very good, but interesting to follow the wave of flavor rise and fall.

I seem to have lost any roasting touch I thought I had. Very frustrated to be wasting time and money. I’m hoping someone can provide some insight on roasting at high altitude. I’m at 4400ft. Thank

TC4 loading problems
JSA Coffee
Here's what I have done to attempt to load the sketches to my TC4.

1. Downloaded and installed Arduino v1.8.7
2. Connected the Uno/TC4/LCD/ZCD
3. Verified the Com3 and board type under the Tools menu in Arduino.
4. Downloaded the zip aArtisanQ_PID_6_6 from Github
5. Unzipped it to a folder on my desktop
6. Copied the folders from the aArtisanQ_PID\libraries to C:\Program Files (x86)\Arduino\libraries
7. Opened aArtisanQ_PID.ino, then Verify\Compile. Other than a low memory message, it compiled.
8. Uploaded Sketch, and got a message in Arduino that said Upload Complete.

The LCD is still showing two lines of black boxes, so based off of the guide, I don't think I got it right.

Try adjusting the pot on the pot on the LCD driver. You can get that, or nothing, when it's not adjusted properly.

OK, it sounds like you're nearly there.

After step 7 when you have opened aArtisanQ_PID.ino, you should see multiple tabs with code in each. The user.h tab has many settings that you will need to check and configure before you upload it onto the arduino.

The key ones to check are:
- Base configuration. You have the ZCD so the default CONFIG_PAC2 mode is probably correct.
- Temperature Unit
- LCD Options. You probably need to change this to the LCD_I2C option. And change the LCD_I2C_ADDRESS to 0x27 if you're using the LCD from me.

To change the options, just comment out the current active setting and activate the desired option by removing the //.

Check the other options too. I'm not sure about your roaster setup so it's hard to comment on those.

I adjust and set the contrast POT when I test the LCDs, but it is possible that it got turned accidently.

@greencardigan, Thanks!!! Once I changed the settings you recommended, the LCD is displaying like it should.

My roaster right now is an electric bake a round version with a spa blower and two heat gun elements. After I have this hooked up and am comfortable with it, I am going to go up in size to around 5 pounds.

Excellent! Don't forget to check the other options and ask if you have any questions.
