Has anyone experienced the "Auto" function not working on the Air Assist. I'm using an S1 with XCS and it doesn't even show up in the settings panel. Everything is connected correctly, Air does work when turning the knob to one of the manual settings. But when the S1 is running and set to Auto no air at all. I had it set to auto since the day I set it up assuming it was working. This has caused a premature failure of the protective lens cover. So far I have had nothing but trouble with this S1 purchase. RA2 didn't work on first try. Xtool sent new main board, cables and the small accessory front board for me to replace. The rear accessory board is the original.
