Hooking up D5 pump to Duet 2
-
I am in the process of installing a liquid mosquito hot end and I need to install a water pump. How would I wire it up? The specs of the pump are below.
Nominal voltage: 12 V DC
Operating voltage range: 8 to 24 VDC
Nominal power (@ 12 V): 37 W Max
Nominal current (@ 12 V): 2 amps
Motor type: Brushless, microprocessor controlled
Maximum head: 13 ft (4 m)
Maximum discharge:
~ 317 GPH (1200 LPH)
Performance will vary based on housing used -
Hello @nightmare90gt the safest and easiest way to wire a D5 is to wire the two +12v and GND pins directly to your psu. One of the remaining two pins is the tacho line indicating the pump speed, which you can leave disconnected. The last, pwm, pin controlls the pump speed and should be connected to a fan output on your Duet. After the proper configuration g-code side, you can control the pump speed from dwc/g-code.
Depending on whether you have a duet 2 or 3 you might be able to hook it up directly to the duet (3) but I am not sure. The method described above is at least how I did it on my duet 2.
I am not at home so I cannot share my fan config. For the which pin is which I suggest googling "4 wire fan pinout"
Hope this helps

-NxtThis is along the I was thinking was just unsure about the pwm side. I have the duet 2 wifi so our setups should be similar in that regard.

@nightmare90gt The fan page on the wiki mentions this in more detail. Normally you can just connect the pwm wire on a FAN- pin duet side.
