@jay_s_uk i dont think the laser pin is bad.
i think somthing is wrong in my setup.
do you have any ideas on what could i do?

let's say ill test it with m42 and i see it works, what next? why doesnt it works normally?

hi guys, im trying to use the gpio pins.
so ive added to my config the following code:
M950 P7 C"io7.out"

to my understand, i now should have gpio p7 configured.

in order to enable it i send the following:
M42 P7 S1
ive also tried
M42 p"io7.out" s1

next, i measure voltage between io7.out to ground and i get 0 volt.
ive tried
M42 P7 S0

and still, 0 volt

any ideas?

@droftarts ok sorry, my mistake, im running 3.4.5
i have idex, both 2 heaters
the 4th heater is connected to extansion board, and i get error
both heaters should be from the main board for some reason..

@jay_s_uk doesnt m42 work only on GPIO?

ive tried
M42 P"OUT0" S255/S1
M42"LASER" S255/S1

nothing changed..

@droftarts i will try.
but i think i prefer anyway to set both heaters to one, as i would never need to set different temps between the two heaters

@jay_s_uk i understand.
i ask you this:
if i set the pwm to 100%, any volmeter should be able to read the voltage.

therefore, i think somthing is wrong in my setup, because i read 0v even at 100% power

@droftarts
i can see that only one heater is active, therfore i guess its only using one.
im using firmware 3.3, and havent changed anything yet(you can see in the post the way i defined the heaters)

@jay_s_uk but wait, if ill try to enable the laser full power, s255, i should read 5v with any voltmeter, shouldnt I?

@jay_s_uk i want to use 2 heaters, i have one thermisitor, im trying to PID tune using both

@jay_s_uk im not sure i understand what you mean sir
