@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

could it b tht maybe the board being the problem

here to i add the g29 s0 after probing or b4?

ok the how do i save grid in correctly

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.

grid not defined

k what could b the reason for this error?

Error: G29: Failed to load height map from file heightmap.csv: invalid grid

i dont have probe yet on my delta so im using the manual leveling, and trying to save to height map so i dont have to constantly do it, but im getting error massage, what cud b the prob

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
