fans not working

hyppo

ok i have a weird issue, i set up my fans to default settings fan0 as controlled, and fan1 to hotend(only have on extruder, on delta). like the following..

M106 P2 H-1
M106 P2 S0
M106 P1 T45 B0.1 H1 ; enable thermostatic mode for fan 1
M106 P0 H-1
M106 P0 B0.1 S1 ; enable gcode controlled fan on 0

but everytime i print (s3d as splicer) it never turns on the fan, even checked the print gcode file, it does send the code to tun it on after say layer 2 , but cooling fan never goes on. even sending a code to printer with paremeter "0" s1 it doesnt even start.

and if i set up p2 as controlled fan, it starts up on printer initial start up and doesnt turn of unless i send sepreate code. nd also s3d only sends "m106 s1" to start cooling fan, and if i have it on P2 it never starts it ither, and i dont want to edit every gcode print i make to tell it to use p2 fan, unles theres a simpler way

Have you seen this? https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans

Are you able to control the part cooling fan0 from the slider in the DWC?

yup i used that link to connect and configure them, and nope, iv never gotten that slider to work, also doesnt even work with the terminal hotend fan.

could it b tht maybe the board being the problem

To test a fan (fan 1 in this example):

Send "M106 P1 H-1 S0". The fan should be off after sending this.
Send "M106 P1 S1". This should turn the fan on.
Send "M106 P1 S0.5". This should run the fan at a slower speed.
To test fan 0 or fan 2, use P0 or P2 instead of P1 in the above commands.

@dc42 i know all that, i know i have my commands right, its still not doing what its supposed to, i there anything else it could b, P0 does not do what its supposed to, if it does work and if i use p2 in initial setup, the fan starts when printer starts up and dont stop unless i send the gcode to stop it, and then just the code "m106 s1" that the splicers send does would not work

It's not clear to me from your posts whether or not fan 0 works when you test it manually. To test it, see my previous post, but use P0 instead of P1.
M106 Snnn without a P parameter (as generated by most slicers) will default to using fan 0, unless you have used the F parameter in your M563 commands in config.g to select a different fan.
