@dc42 wow, thats a good thing to know. As I understand when I open the valve, I can just after few second use same comand with half of power just to keep everything open. Amazing

@dc42 I am planning to use solenoid open when router bit hits the aluminum surface, basically to blow the mist, usually it takes about 7 minutes, do you think it might be a problem to keep ot open that long?

@richardmckenna thank you so much for you support. Very, very helpful.

@dc42 thank you for you help. Amazing support.

@dc42 Thank you guys, you are amazing. And the command in the gcode is m106 0 255?

@richardmckenna that is an amazing info. I can see where 5V is written the pin is without the cover, and nearly I can see plastic part covering v_fan and vin, so it means it is 24V powered?

@dc42 I use from Ooznest it is 24.4V. But as I understand fan0 port provides 1.5A and 5V or I am missing here something?

@dc42 I am lost here, so I can connect this solendoid valve even if it is 12V or 24V to the fan0 pwm port? How is it possible ir duet port is just 5V?

@dc42 I would like to use something like that:

Solenoid Valve Model : 2W-025-08
Body Material : Brass
Working fluid : air, water, oil
Type : normally closed
Take over pore diameter : 1/4 "
Flow pore diameter : 2.5mm
Seal Material : NBR
Voltage : 12V DC
Pressure range : 0 - 1.0Mpa
Fluid temperature : -5 - 100 ℃

I would like to connect it to my existing air system with 1/4 inch connection. It seems that it uses 12 DC power. How should I connect it correctly? Should I use realy with diode? If yes, any spwcifig diode and relay needed?

Hi guys,
I have a workbee with duetwifi and I am using it for woodworking. At the moment I have attached to my cnc air blow and I use it manually with my hand to open or close before starting a gcode. What I would like to do is to use fan0 pwm port to open or close the valve with gcode command. As I undersrand it is possible with relay, diode and solenoid. Coul you please help me out what is the right way to do it? I am a woodworker and I would appreciate very clear advices and comments as I do not have any electrical background.
