TC4 with aArtisanQ_PID
MaKoMo wrote:

I uploaded a public beta of Artisan v1.2 on its GitHub home.

Thanks for your help Marko!

KKTO Roaster.
I uploaded a video as it works practically and from start to finish fully automatic (80/70mm fluid bed roaster 1.7kW, 500W motor).
I changed the thermocouple and set the position in the roasting chamber so that the degree of roast corresponds exactly to a bigger (120/110mm) roaster in the same profile.
The small roaster can be used as a sample roaster.

I'm inattentive, currently I use other button settings:

How do you get that RoR guidance curve on screen, is it added in post processing, or an Artisan feature ?
DIY: IR to bean, Popcorn
Moded commercial: Dieckmann RoestMeister, Nesco
PID/ramp/soak controllers, MS6514 USB/Artisan/App
Grinder: mod'ed Porlex to 47 conical burrs
=deltBT in Artisan extras
This is real time RoR plot, I have this checked, is not what I meant, but the curve already on screen before the roasting started.
You probably think of the DeltaBT in Profile Background.
Profile were created in Artisan Designer.
So I added fan control to my TC4 with my Quest, works great! Does anyone know how to get an LCD that would tell me my fan output? I was looking for something that would give me the duty like the heater (OT1), but I can't find anything...I need an OT2 readout.
The TC4 sketch supports a connected LCD (16x2 or 20x4) using the LCDapter board that Jim sells.

I think it may also support a standard parallel interface but I've never tried.

I want to try using one of the cheap i2C LCDs available on ebay instead of the LCDapter but haven't tried this yet either. It would required a few tweaks to the sketch.

Alternatively, you could connect the TC4 to a computer and monitor/log the outputs using Artisan.

Or add a bluetooth module and monitor outputs using my android app.
@greencardigan, I guess I should have been more clear, I want to be able to log the fan output using artisan. When I said LCD, I was referring to the mini LCD's within artisan.

I just can't seem to figure out where the OT2 data feed is within artisan. Any ideas?
Have a look at my videos here.

Similar roasting, only the fan slider moves, is here:

If there is someone who has tried TC4 shield + Arduino Mega, write here.
I'm interested in any result. Also, that something did not work.
Brad, those ebay I2C won't work, wrong chipset, I've probably got about a half dozen I could send you, some still wrapped. some off the backs of displays I had too take off. Now, if you want to wright new code, You can probably make it work. It takes a lot more than changing the address.

Now, what I will do, I will send you a Digole TFT if you will send me a copy of the sketch you have to use to get it working. I've got q 2.2 I2C one I ordered wrong for a battery tab spot welder and I cant even figure out how to change the address in. I've never learned enough Arduino to program. 2.2 is pretty small, a lot smaller than a UNO board. so I'm sure you would want something larger than that. If interested, send me a PM.
The reason I suggested the Digole, they are well supported with documentation and user forum for someone that understands this stuff a lot better than me.

Yes, I understand I would have to use a different LCD library to get the ebay I2C LCD working. With the LCDapters being hard to obtain, an easy to source alternative would be good I think.

Getting the TFT to work would also required a different library but would probably be more complicated. I'd also be worried about the memory available. The aArtisanQ_PID sketch already has very low memory free.
Shoot, I thought I might slip one over on you.
To keep from getting this tread any more off subject, I sent you a PM.
