@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

@jay_s_uk im not sure i understand what you said

As ive wrote above, i am using m452 ("M452 C"out9" R255 F500")

so, in order to activate the laser, i should send the gcode :
M452 C"out9" R255 F500
t2 g1 s255

and yet, i measure 0v from out9 to ground

@jay_s_uk im using firmware version 3.3

hello everyone, im trying to setup laser module
this is my setup:
; Laser module settings
M563 P2 S"V" X3
G10 P2 Y0 V0 Z0 S0 R0 ; set tool 2 axis offsets
G10 P2 V0 Y0 R0 S0 ; set initial tool 2 active and standby temperatures to 0C
M106 P2 S0
M452 C"out9" R255 F500

im using diy idex printer which "U" corresponding to the laser tool head

the laser is not connected yet. im using voltmeter to measure the out9 pins

followed by the instructions manual, im sending the gcode:
g1 s255
or
t2 g1 s255

both of the gcodes doesnt change the PWM voltage at the out9 pin(out9 and ground)

any ideas?

@jay_s_uk so you think i should map
heater 1 output out1+out2
heater 2 output the same? out1+out2

@jay_s_uk i think you didnt read everything

"if i send m303 t0 s220 it only uses one heater"

hi, im using 2 heaters for my hotend
ive defined them, and i can get them to heat up, im using one thermisitor
heaters setup:

M308 S1 P"temp1" Y"PT1000"
M950 H1 C"out1" T1
M950 H2 C"out2" T1

tool setup:
M563 P0 S"X" D0 H1:2 F0:2

now, i want to tune pid both of the heaters, but i can only tune one of them

when i send m303 h1:2 s220 i get error for some reason it try to tune heater 0(BED)

if i send m303 t0 s220 it only uses one heater

any ideas?

@Phaedrux yes

@dc42 thanks

@jay_s_uk the problem is not offsets, its the way duet define toolheads
it defines them as new axis instead of new extruders/tool heads

@o_lampe hi, i fixed the heaters, and the fan was connected reveres polarity

now, i have different problem after everything heats up perfectly

usually if i want to use tool head number 1 i just add t0 to the gcode, and then everything normally, same with t1

but in this reprap firmware, seems like in order to move 2nd print head i need to send u100
i mean, the second tool head is a whole new axis.
what slicer know how to deal with it?
