In config. g
;LED Strip
M950 P2 C"e1heat"
M307 P2 A-1 C-1 D-1Then add the following to change power output
M42 P2 SxxxDone! When I boot the board the pin is setted "high" and the LED stripe is immediately turned on with the maximum pulse width. How can I set to let the pin low when the board starts?
-
Make sure the M42 code is in the slicer startup code and NOT in config.g
I put M32 in my slicer start code which calls beg.g and M0 in my slicer end code which runs stop.g
Then I have M42 P2 S255 in my bed.g and M42 P2 S0 in stop.g and cancel.g

already done but the stripe turns on when I boot the board even without m42

@the_dragonlord can you share your config.g file?

uh, I forgot to say that I'm using a PWM fan not an heater.....sorry....

Which fan header and where is the gcode defining the pin?
-
@the_dragonlord your problem is you have m106 P2 S1 H-1 and you should have m106 P2 S0 H-1
-
@the_dragonlord but I recommend you use a heater and not a fan

i can't use a heater because I have to trigger a mosfet to drive the stripe and overriding a heater pin it gives a level of tension not enough for the mosfet to switch. Ay niw I'm using the Fan 2

excellent, thanks!

@the_dragonlord I'm driving the LEDs directly from the board so that I can control the brightness. But if you are driving a MOSFET, then the fan is a better option I guess.
