Yes that is correct. If the SD card is in the Duet it would try to work in standalone mode. It must be removed to work with the SBC.

@PDBeal as @Phaedrux suggested is the best Pi4 or above is better, depends what you wanna do with it, I use a Pi3b+ for my 6HC but just for dwc and updating, my 6XD has a Pi3a, there is a post on the forum of people using a Pi zero 2, spoiled for choice lol

@Phaedrux Very cool... thanks I have not seen that. 😞 I cross reference from the g-code dictionary in the M593 section to the howto may be nice to have. 😉

Cheers, Chriss

@Phaedrux said in Homing using additional Z max stop switch with a Duet2 WiFi:

I have a set of macros I use to measure the exact distance from the probe determined Z0 position to the zmax endstop position.

Your macros have sent me to read the RRF documentation. I understood what they do and will definitely use them, although perhaps changing the commands G1 Sx to G1 Hx:
" S parameter sets laser power with range of 0-255 when M452 Laser mode set, otherwise ignored. "

I also understood how homing can be implemented to achieve my goal, thanks a lot.

@developerOI if you have swapped out the Duex5 and that one works then please contact warranty@duet3d.com

I see you bought this directly from Duet3D.

I have re-checked the board and it seems working correctly. It must have been some mistake of the service department. Sorry for bothering, the case can be closed for now.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@p8blr the link I posted suggests a 2K2 pulldown resistor and a 10K to 15K resistor to the output of the sensor.

@dc42 Thanks a lot David, I should definitely forget it 😉

@new_to_me901 Then I cross my fingers your machine will run again soon 🙂

@OwenD
That is what I did, thanks.
Now I am tuning the value of the S parameter in this line of the config.g file:
M915 X Y S30 R2
At S30 no stall events reported yet, but they were reported at values smaller than 10 (false positives).

@Classified just a heads up, this is a 1.45A fan and Duet supports no more than 0.8A on the 12V rail. So you must use an external 12V power supply (or buck converter) on this.

As this is a 4 wire fan, you could connect just PWM control to the Duet board while running VIN and GND to a buck converter that is fed by your main PSU. Connecting the fan monitoring wire reporting RPM is optional..

@gtrider

Trank YouTube this helped and the extruder works Fine 🙂

@Arminas you could use a Duet 3 Mini but it would be overkill. If you don't need an Ethernet connection then a 5V Arduino connected to a mosfet and flyback diode to drive the solenoid would be simpler and cost less.

@polbebe do any other components get hot apart from U4? It's possible that some other component powered from the 3.3V internal rail has failed and is overloading the regulator. Check the main microcontroller in particular.

@dc42 Hello, when I tell DWC to heat up the hotend, the heater turns on and two seconds after that it shows the fail

@RockB

Looking at the pin-out of M23CL, I see two pairs of CAN_L and CAN_H (one each for incoming and outgoing I think). I can daisy chain the outgoing pair to the incoming pair of another motor.

Yes, that's correct.

Should the motors be wired in-between the other boards on the CAN bus or be used as the last device on the bus? Is there a termination resistor built in?

The 23CL is supplied without CAN termination, so is easiest to use between other boards. If a 23CL needs to be the last device on the bus, there is a solder jumper on the PCB inside the motor to enable termination, but you would have to take the rear cover off the motor to access it. We recommend using external termination if the 23CL is the last device on the CAN bus. Connect a 120 ohm resistor between the pins on the 'outgoing' wire pair, between CAN_H and CAN_L.

The documentation says "Multiple M23CLs can be connected to the bus, either via an M8 Y splitter or a distribution board/box". Is this available as a product? Any wiring diagrams would be appreciated

M8 cables are pretty widely available. Generally, you can use 4-wire M8 cables. What kind you need will depend largely on your application.

T splitters (not Y splitters, they tend to have the wrong connections) with 4 positions on all connectors such as https://www.te.com/usa-en/product-T4082102004-000.html (widely available from Mouser/Digikey/RS/Farnell etc) should work. Plugging in with the middle connector of the T will obstruct the 23CL power connector, so either use the other female connector of the T, or have a short jumper cable between the T and the 23CL.

For 'distribution board/box', you can use the Duet 3 Tool Distribution board, and wire each 23CL in the same way as a Toolboard 1LC. Bus termination can then be done on the Tool Distribution board.

I'll add the above to the 23CL documentation.

@Gordon-Lin
did you get it up and running with the micro switch in the splitter?
