Re-format on-board memory

This is necessary whenever you get the message:

There is a problem synching with the roaster. (SYS ERR)

First try a safe re-format. In more extreme cases a complete re-format will be necessary.

Safe re-format (preserves logs and profiles):

Make sure you can access the Kaffelogic Studio connection tools menu. If it is not showing in the Tools menu, select Difficulty - Engineer.
Select ‘Re-format on-board memory’
Select ‘Re-sync’

The re-sync will copy all logs and profiles back onto the roaster.

Complete re-format (CAUTION: deletes all logs and profiles):

Make sure you can access the Kaffelogic Studio connection tools menu. If it is not showing in the Tools menu, select Difficulty - Engineer.
Select ‘Re-format on-board memory’
Unplug the cable to the roaster
Select ‘Open roaster sync files’ and delete both logs and profiles folders.
Re-plug the cable to the roaster and restore the core profiles using the core profiles tab of Kaffelogic Studio
