Thank you for pointing that out. How can I now control the operation of the relay during a tool change?

Hallo!
I run a Hypercube double extruder with a duet wifi board. Two-color printouts are not particularly successful, as the slicer features for double extruder tasks are only an emergency solution. Optimal is an automatic lifting of the extruder during color change. I would like to realize an autolift similar to the Ultimaker 3. For this I have a magnet coil, which is supposed to lift the two extruders alternately. This responds at 24V DC voltage. My question: Where can I connect my coil on the board and where can I set this connection in the configuration when changing extruders?
Many thanks for your help
