I ran into an issue with an older Falcon2 22w getting lightburn to connect.
I purchased the unit about a year ago and am just getting around to setting it up. I imported the Falcon2 configuration into lightburn and on power up it cycles through the startup sequence and then when the air pump stops the red air light is on.
I first checked to make sure the hose and air is flowing freely, and I also made sure the dial is set for max airflow.
I then did a firmware update and the system firmware went fine but the laser firmware update hung. After more than 5 minutes the lights were still scrolling left to right and I powered it down. On a second attempt it appeared to quickly do the laser firmware update.
I still have the flashing red light but the Falcon2 is unresponsive to any commands in Lightburn.
