Duetwifi solenoid connection

@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?

The fan ports are switchable (as a block) between VIN and 5V. So I recommend you purchase the 24V version of that valve. It will also draw half the current of the 12V version. Search for "2W-025-08 24vdc".

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

You can use M106 P# S1.0 or M106 P# S255, where # is the fan number. If you will keep the solenoid energised for a long time, then you may wish to reduce the current after a second or so to reduce heating. For example M106 P# S0.5 will reduce it to half current.

@edmundas323 yeah take a look here https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams you want the jumper on the VIN and V_FAN pins.

@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?

Probably not, but it's so easy to reduce the current after pull-in that you might as well. Most solenoids need much less current to hold position than they do to pull in.

@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
