Hi, I have Flacon A1 10W and a stronger external air assist.
I want to switch on teh external air assist with the output of the A1 (via relais or MSOFET).
Who knows the pinning and signal logic og teh A1 air assist output?
Creality supports doesn’t help.
When I measure the 3 output pins, I can’t measure an voltage between them to re-engineer the pinning.
On older Lasers it was a simpler 24V on/off - it looks like A1 has a different logic?
I measured now the output myself and suceeded.
When AirAssist ist off: you get an 24V 4s per period PWM signal.
When AirAssist ist on: you get an 24V 16s per period PWM signal.
see pics attached.
Looking at athe A1 port, the upper left Pin is +, the one down is the PWM “minus”, so measured against the + Pin
