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.

Hi @dc42 ,
I'm trying to interface my CO2 laser with duet 3. It has +5V TTL laser power control pin which is used to control the power for which I'm going to use LASER/VFD (v1.0 boards only) which is available on the board. But this CO2 laser need input of 5VDC PWM pulse of 1khz on Laser enable pin, I'm trying to produce on FAN pin out5. I used

M106 P2 S0.5 F1000   ; Turn On FAN 2 S0.5 for 50% duty cycle with frequency of 1Khz 

for 1khz of frequency on fan 2 but getting some random frequency value from 100Hz to 50000Hz on pin out5 with respect to ground. Looking for suggestion is it good idea to to use FAN pin for PWM tickle pulse and how can I measure it using DMM ?

Can you share output of M122 command and try cold extrude using M302 P1 it'll enable extrude button. Check if extruder motor making any noise.

@dc42 I was trying to add project in vscode. It was taking too much time create Makefile so left it in half. Thank you for the help Sir.

That worked but now getting other linker errors. Multiple definition in networking.

one of them is given below.

Hi @dc42 I'm trying to compile reprap firmware 3 for my duet3 board.
I've donwloaded branches and using build configuration as given below.

RepRapFirmware: v3-dev   - Duet3_V06
CoreNG: dev  - SAME70
FreeRTOS: master  - SAME70
RRFLibraries: dev  - SAME70_RTOS
DuetWiFiSocketServer: master
CANlib : master   - SAME70

but getting error as shown in screenshot.

I've not made any changes in code.

Hi @dc42,
I'm trying to use Nema 23 motor with duet 3 expansion board 3HC. Both the main board and expansion board are connected to a power supply of 30V, 16A supply.
Case1: Nema 23 motor connected to expansion board: motor not moving, but vibrates a bit
Case2: Nema 17 motor connected to expansion board, same configuration as before: motor working perfectly
Case3: Nema 23 motor connected to main board: motor working perfectly

Can you suggest something so that I can use a Nema 23 with expansion board?
