To run the projector serial diagnostic, you need to make sure that Photonic3D has been stopped. On Linux you might perform the following command:

sudo pkill -9 java

Then execute the following command and follow the prompts to determine if we are able to communicate with your projector:

cd /opt/cwh
sudo java -Djava.library.path=/usr/lib/jni:os/Linux/${cpu} -cp lib/*:. org.area515.resinprinter.projector.ProjectorOutput
