Baking automatically stopped due to negative gradient in on thermocouple for 10 minutes straight. 
Not surprising giving we were baking at full power bu making little progress. We should have switched to manual
mode.

Switched to manual mode for now at 60 C to recover temperature without excessive gradients. 
Will restart automatic mode later today. Should be back to full power tomorrow morning.

EDIT
21:42 CET - Temperature stabilised. Restarted automatic mode.
