Adding a Cpap blower to a duet 3 mini 5+
-
@droftarts never mind I got it now I was using the 5v out that must be a Constant instead of the “buff” pin it works as it should now thanks for your help
-
@droftarts one more question is there a way to set the max voltage output lower so when I’m using it as a cooling fan at 100% it’s really only 50% of what it can do?
-
@ratrig0331 if you define your output with a M106, you can set the max. speed with the X parameter.
-
@cosmowave ok so it would look like this?
M106 P1 C”Cpap” S0 H-1 X.5
-
@ratrig0331 Yes. I think this should work

@cosmowave thanks I’ll try it out tonight when I get home
-
@cosmowave that worked to slow down the blower thanks!
-
@ratrig0331 Just curious what you're using a cpap blower for... to control your duet machine or to help with sleep apnea?
-
@code7 no I’m using it for part cooling on my 3d printer to bring cool air from outside my enclosure in. Yes I know that sounds a bit counter productive for a enclosure. But I was having a problem with the enclosure getting too hot inside not only for part cooling but melting the 3d printed carriage as well. My chamber is heated but only turns on to help stable out the start temp after that the large 510x510mm bed heater keeps things around 60c at a bed temp of 80c than I use 4 side blowers that draw from the bottom of the enclosure to the top to circulate the air evenly

@ratrig0331 Great use of an old cpap machine
