signal exchange with an Arduino DUE / YUN-Shield
My intention is to link the Repetier-Server with an Arduino DUE / YUN-Shield to send a flag which is indicating the END of the printing process (Repetier-Server is running on a Raspberry-Pi). The Arduino unit is controlling an internal heating subsystem of the printer to heat up the processing box inside. The heating is an experimental auxillary equipment, which is recently on/off-switched by hand, so that the aime is to stop the heating after finishing the printing job automatically. Any ideas to pick-up such a flag from Repetier-Server?
