Here is a copy of the LED codes for the FB3-QS:
LED light codes
The front LED next to the USB connector indicates the current function the FB3-QS is executing:
•Solid Green -Powered (connected to USB but no connection to QuickShow)
•Solid Yellow -Connected (to the Quickshow or other software), but offline
•Red Slow Flash -Online, but output inactive (dummy stream, no cue active)
•Red Fast Flash -Online and output active (at least one cue active)
•Yellow Slow Flash -Online but output disabled (either invalid license, or some other fault)
•Solid White -Firmware update in progress
Based on your description of the LED shades, everything seems to be working as it should. Can you advise what "level" the red LED is flashing when you click on a cue and Enable Laser?
A quick suggestion would be to verify you do not have a "demo" unit for some reason as your main projection zones. Click the "Settings" menu and choose Laser Hardware controller; if there is a "demo" unit listed, remove it. If there isn't, go into the Projection Zone settings and make sure your FB3 is set to the Main Graphics projection zone.
