A update is expected “soon TM” :smiley:

The latest firmware CV-30_V3.0_24 have some kind of bug. I had the same issue with GPIO.

Downgrade to CV-30_V3.0.20_20220427 and have fun with LaserBurn 1.60 :slight_smile: beta

BTW… I have 2 full sets of Falcon 10W (order from Aliexpress - they send me 2pcs :shushing_face: but I ordered only one)

On second device is the same GPIO problem.
