We are excited to have a new beta firmware that makes the Bullet R1 more quiet!
In this new version, the cooling fans for the electronics are being adjusted with a PID controller which under light use runs the fans at a lower RPM, making the Bullet more quiet.
Also, if you are still on an older firmware, we are now testing a new preheat setting of 205 Deg C, but remember to clean the IR glass to prevent overheating.
In addition to this, you can now change the volume of the lady talking to you - press F1 for the menu, then press the top left button.
To update your firmware to V428, please use RoasTime and the password: improvements
Should you experience any issues, please report them here or to Aillio support on facebook or email.
Happy quiet roasting.
