@Nomad As a general rule Roasting should not exceed 20 min to second crack You are describing is baking

Arduino TC4 Artisan output's not working

First I'll say that I am able to get Roastlogger working using their arduino sketch but I can't get any outputs from any form of artisan code. Currently I'm running REL-aArtisanQ_PID_3_7 and I have also tried several different older versions with no luck. My setup uses PWM out from OT1 which is going to a mosfet then to a Clippard solenoid, and like I said it works just fine through roastlogger and their version of the sketch so I know that the hardware is functioning. Fan is manually controlled for the time being so that's not something that I need to worry about. Could someone who is also using PWM from OT1 attach their working artisan sketch folder? Or if someone could talk through the setup? I have done a lot of searching and nothing is solving my problem. Thanks!!! Royce

I know it's up to 6.2 because I just downloaded it to play with the Android Bluetooth app for it. Something I started back when it was first released and didn't have time to do anything with it, now, I'm going to try it again and have forgotten what little I did know about it. https://github.com/greencardigan/TC4-...tisanQ_PID Try here. https://github.com/greencardigan/TC4-shield/tree/master/applications/Artisan/aArtisan_PID/branches/aArtisanQ_PID_6/aArtisanQ_PID Edited by BenKeith on 11/17/2016 9:28 PM

Note that it is still in testing phase although I've had reports that all is fine. http://forum.homeroasters.org/forum/v...post_59700 I suspect you want to use the PWM control option, which gives slow PWM (adjustable) output on OT1. You will need to adjust the setup options in user.h to activate the PWM mode before programming your Arduino. Alternatively, try one of the latest base variant of aArtisan version 3.1 https://github.com/greencardigan/TC4-...n-V310.zip

I had previously tried v6.2 and I'm not sure what I did wrong but its working now! Thanks! Royce

Code Download source #define HTR_CUTOFF_FAN_VAL 0 // cut power to Heater if fan duty is less than HTR_CUTOFF_FAN_VAL (to protect heater in air roaster). Set to 0 for no cutoff This option needs to be changed from 10 to 0 if you are ONLY using heater control and not fan. Once you read what it does it makes sense, but without digging I wouldn't have known to set this to 0. Maybe it would be helpful to have a PWM heater only control option that would automatically remove or set this to zero.
