Can Extruder pins are use to ON/OFF Solenoid valve??
-
Hi guys,
I want connect solenoid valve to extruder motor pins like in ramps we can do on/off by extruder motor driver pins which are DIR and ENABLE. and connect to the L293D driver where I can give GCODE from Slic3r. Now I moved to Duet board so how can I operate solenoid valve. Please help me in this.

The recommend way to drive solenoids is to use spare heater or fan outputs. The fan outputs are rated at 1.5A and on Duet PCB versions 1.02 and later they have integral flyback diodes. The heater outputs are good for about 6A but have no integral flyback diodes.

hi dc42,
thanks for reply. but this I am using for chocolate printing where it is a pneumatic based extrusion. in that i want to ON/OFF solenoid valve. In my case I cannot use fan pins . please help in this.

This command https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M571_Set_output_on_extrude may do what you need.

hi dc42,
I am asking that my printer is a paste extruder. I am using pneumatics to drive the chocolate from syringe to the bed. and for bed I am using peltier setup where i can change in the middle of printing. Now I want to operate solenoid valve on/off for that i want to use extruder motor pins. please help me

@allankisaiswaroop, you don't need to use the extruder output pins to control the valve, see my previous reply.
