    • RE: Using FAN Pin as a GPIO in Duet 3

      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?

    • Using FAN Pin as a GPIO in Duet 3

      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.

    • How to turn on duet3-3hc using 5v supply?

      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 connec.jpg to duet3-3hc.jpg 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.

    • RE: PWM in Duet3 for CO2 laser
      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.

    • RE: About the pause function

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

    • Mini Differential IR Sensor

      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.

    • RE: Generate Tickle Pulse for CO2 laser using duet3 board.

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

      ;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.

    • RE: Generate Tickle Pulse for CO2 laser using duet3 board.

      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.

    • Generate Tickle Pulse for CO2 laser using duet3 board.

      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 ?

    • RE: Duet 3 Extruder control disabled

      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.

    • Nema 23 with Duet 3 expansion board.

      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?
