My roaster has 2 Fuji PXR-4 controllers. One measures the drum temp (BT) and the other one the environment temp (ET).
I am able to set these in the configuration, but when it displays on screen the ET and BT are backwards. On the controller(s) display, the temp reads correct, but not in Artisan. I have tried to toggle the ET/BT option, but sometimes it switches to the correct state briefly then reverts back to the wrong reading, or it does not switch at all. I have had it reverse itself mid-roast for some reason.
The controllers themselves are not locked and can receive outside communication as far as I know. However messing with PID or Ramp/Soak values seem to generate an error.
Cant seem to find much on Artisan/PXR-4 setup.
I have Artisan installed on a Linux (Debian) laptop.
