Firmware update: ver 7.4.5   

released 3 June 2020

Your roaster will continue to work safely whether or not you update the firmware, but we recommend updating to the new version to get the latest features. Version 7.4.5 has a new extended cooldown that is particularly recommended for back-to-back roasts. This is designed to let you roast consecutive batches without having to wait in between. 

  1. Download the update to a memory stick. 
    • Launch Kaffelogic Studio and select the 'View memory stick' tool and the 'Firmware' tab. This lets you download and save the update file with a single click.
    • Alternatively, download this file Firmware version, make a folder named kaffelogic with a subfolder named firmware on a memory stick, and copy the firmware update file to that subfolder.
  2. Put the memory stick in the roaster.
  3. Hold  ▶ down while you turn the power switch on and the firmware will update off the memory stick.

Roast profiles

The Nano 7 comes pre-loaded with a default profile called "K-logic classic." This profile makes a fantastic job of most coffee varieties at a medium roast. Experiment to see which level of roast you prefer.

The core profiles are a set of 12 profiles that allow you to fine tune your roast profile to your coffee and your tastes. You can read about and download them on our community forum. There is a guide and map on the forum post, and this is required reading for using the core profiles. The core profiles can also be downloaded as a zip file. If you download the zip, you will need to copy the 12 profile files into the /kaffelogic/roast-profiles folder on your memory stick.

More roast profiles are available from our community forum.

Once you have found a profile on the forum, download it and open it with Kaffelogic Studio. Put a USB memory stick in and click "Save to USB".

After you have saved a profile on your memory stick, put the memory stick into the roaster and press the 'profile' button. This will let you load the new profile into the machine. Adjust the level, and you are ready to roast.

This interactive coffee taster's flavour wheel is a useful resource for those of you who are developing profiles.
