Solved the issue, GPIO pin is working when a device is connected to that. Earlier I was checking output on out4 using a multimeter and it was showing almost 0V. Any idea how to detect this pwm signal on out4 using a multimeter or scope?

Hi Sir @dc42 , I've Duet 3 6HC V1.0 I want to use FAN out pins(out4, out5, ou6) as a GPIO out pin. Tried configuring the pins using

; configuration
M950 P0 C"out4"
M950 P1 C"out5"
M950 P2 C"out6"

; console
M42 P0 S1          ;  turn on pin out4 
M42 P1 S1          ; turn on pin out5
M42 P2 S1          ; turn on pin out6

But there is no output.
Tried Inverting pin. Nothing works.

How can I use this pins as a digital output pins?

Thank you.

Hi @dc42 , Hope you doing well.
I want to power on duet3-3hc Expansion board on 5v, like main-board.
I planned to connect This commponents to here, on 5V_EXT and 5V_INT pin. For 5V_EXT from one of the IO_X(5V_EXT) header pin and for 5V_INT test pin_23(TP23) of duet 3 expansion board.

1. Will it cause any issue After I power on 12/24V main power supply?

Thanks.

Yes, Sure. LaserManual.pdf This is the manual I have.

1. Yes, I need PWM value of 0.001.
2. Yes. That is on the same pin as main PWM.
3. Yes. 1kHz also a good frequency to operate but want to operate on high frequency while firing the laser.

yes. Machine stores the last location and starts to print from same location.

Hi All, I want to test mini differential IR sensor with my Duet 3 hardware based 3d printer. IR-sensor github I found repository for this but could not find the schematics. Where and How Can I get schematics? any link to it.

Thanks.

@dc42 @T3P3Tony Sorry For the late reply. So, the connection I'm planning to use is given below.

;Gcode using to set output on pin
M950 F2 C"out5" Q1000							  ; create fan 2 on pin out8 for tickle pulse of frequency 1khz		|out8
M106 P2 S1 H-1

I'm don't have much knowledge of hardware. Can you help me with it? And what more connection can I do.

Hi @Phaedrux , Where can I get the kicad schematic file of Mini Height sensor board. I can see .png files of schematics and board on Github Here.

Yes I got that. Checked and corrected it. But still getting the random frequency. May be It's DMM issue. I'll check the signal on CRO. Thanks for the help.
