I can't seem to find 'vfan' jumper on the Duet 3. Please advise?
There isn't one, actually. But you can find a source for 5v right in the same block as the PSON pin in the ext_5v block along with ground.
Thanks so much for your help again! I am sorry but I have been putting out fires elsewhere recently. I'm spending the next three days getting this online hopefully! I now understand where to plug the Duet 3 into the power relay but there are two more wires coming out of the power relay: the + and - 'signal' wires as illustrated with the green questionmark in this diagram. Do you know where these go please @Phaedrux @dc42 ? Many thanks

I have so many questions and issues. I am sorry I do have learning difficulties. Is there a consultant who I can hire by the hour to help me develop the firmware config, SBC and operation pipeline for this printer / these electronics please?
I’ve invested all I have into this just time is really short now and I need to get this printer working again and this is the way I think I could make best progress towards a repeatable solution.
Please advise. Many thanks

I can set my workshop up with the webcam and zoom on the screen and we could work through the setup remotely. Please advise if there are any Duet engineers who might be interested? Many thanks, Charles

@charles-fraser Under normal circumstances I would be glad to take you up on your offer, however there are just too many things going on in personal life right now. If no one else steps up to take your offer, please feel free to continue asking your questions here. We will get you going eventually.

@phaedrux Thanks, is there anyone who works for the company that you could think of? The business model for most opensource software is to profide the software and charge for support. It would be good to do that here as so much support is going on in the forums. I'll keep it all open I just can't get this SBC to show up anywhere. Thanks, Charles

@charles-fraser I need the schematic of that relay board so that I can work out what it is supposed to do and how to connect it. Can you trace it?

@dc42 Hi there, thanks! Did you see the diagram I posted above? Otherwise can you send me an example of the kind of schematic you need please?
New developments: I have the Rasp-Pi running flashed with the Duet Rasbian image and it recognises the board. I'm working on config files now but have loads of errors for my first config so I am trying to fix those based on the error type.
-
@charles-fraser Your schematic is cropped, can you please provide the complete one? Also, the configtool lets you uncheck "Run in standalone mode without SBC" which you should do with a RPi attached:
Also it will help if you provide your config.g as well.

@chrishamm hi thanks Chris, I provided the full schematic above too. Here it is again. There is an on off button on the front of the printer. I think that goes where indicated. There is just one wire, the signal wire, with + and - I can't work out where that goes. It's not essential to have the on off switch but it would be nice to have one on the front of the machine where I work rather than having to run around the back to the mains where the power board is. Thanks!
-
@charles-fraser Thank you, can you please share your config.g as well?

Hi gents so after a few hours of work today here is my progress. I have the Rasberian Duet image on the Pi and thats working. I'm able to upload config files to the Duet 3 and have just tested my second config file (here are the config and bed files that might be relevant):
The fan on the extruder is spinning albeit with very very low power. I have two fans hooked up in series there but will sort that out using the fan cables from the second extruder that came with the printer that I don't use. Otherwise here are the highlights:
- When I try and move x or y motors it says:
When I try and home it makes noises but nothing happens. Maybe upping the mA power to 4000 will help to make the X & Y Nema 23 motors move.
-
The status light is flashing orange steadily on the main board. I tried searching but can’t work out what it means. What does it mean?
-
ENDSTOPS: How to setup z end stop. It’s a 3D Touch with a little switch wired into it? I can’t turn on the ‘Endstop type > switch’ in the config menu. 3.1 Is ‘low end’ when it’s at the furthest point from the extruder or closest?
3.1 Is ‘low end’ when it’s at the furthest point from the extruder or closest?

I have swapped the Thermocouple for a thermistor for the Nozzle thermistor because the thermocouple is not sheilded and runs down a rubber wire to the board alongside all the motor cables etc. I plugged it into ‘Temp 0’ on the expansion board but I only see PT1000 as an option with temp 0 (what is pt1000 please?).
-
How to set up additional z motors.
Where does the Gcode go that has to be entered into the ‘config’ and ‘bed’ file it does not say?
Is this right?
File config.g:
M584 X0 Y1 Z2:3:4:5 & DRIVER 0 on expansion board, what is the code for that (set as E3 in configurator);
four Z motors connected to driver outputs 2, 3, 4 and 5M671 X-15
215 Y190:-10:190 S0.5 ;
What is the co-ordinate convention here? I can’t work it out at all. This is the location of the four z motors

How to set up the 5v Pam as a fan to cool the boards with the Noctua please?
-
Here is a table with where all the wires are if that helps:
- It would be really great to have a video tutorial series that gives an overview of how the Duet ecosystem is designed and a crash course overview course on how to modify config settings with clear diagrams and high quality images ect. I'd be happy to help. Please direct me if there is an idiot's guide somewhere please. Many thanks
Charles

p.s: I tried it with 4000mA per nema 23 and now when I press ‘home’ x it clicks and clicks and cracks like something is being pushed and about to snap. I Try to press move x in the other direction and that doesnt work because of the same above fault, no home

I think the firmware on some of your boards is out of sync. Can you send send M122 and M122 B1 from the command console and report the results? The firmware should be 3.3 all around. If not, updating them all will be the first step.
-
@phaedrux thanks I’ll try
-
I'm guessing that means B1 is not speaking the same language (firmware) so will try to follow the firmware update instructions
-
How do I find the address of the expansion board please?
'If the expansion board is already communicating with the main board, send M997 B# where # is the address of the expansion board. The expansion board will commence a firmware update and the DIAG LED will go out for a while. When the update is complete, it will flash and re-sync with the main board.'

 @phaedrux
I added the 'Duet3Firmware-EXP3HC.bin' firmware file to the /sys folder (it would be good to have a link to where these files on gitub are on the Getting started with duet page) by opening the zipped config file from the Duet firmware config, then copying the above file into the /sys folder, then zipping it again. When I update the system files on DWC it uploads all the files then gets stuck on the 'please wait while the updates are being installed' loading graphic.
Could this be because now there are two firmware files in the /sys folder? One for the mainboard and now another for the expansion board? I've left it updating for 20 mins which seems way too long and it doesn't come off this screen.
Please advise and please explain every step very clearly explaining how you do something step by step. Often so much knowledge is assumed that it's not clear how to do what you say to do

P.S What on God's sweet Earth does this mean?
A diagram maybe?) I have the correct cable specified
'RJ11 twisted pair cables to connect the expansion board(s). When connecting a version 0.5 Duet 3 main board to an expansion board, the wires must be crossed. When connecting a version 0.6 or later Duet 3 main board to an expansion board, or connecting two expansion boards together, the cable wiring must be straight-through. Only a single twisted pair is required, connected to pins 3 and 4 (the middle 2 pins) of the connector. Pins 2 and 6 on the version 0.6 Duet 3 main board are the connections for the secondary CAN bus, but the firmware does not use this yet.
2-core red/black cable to daisy chain power to the expansion board(s)' -
P.P.S: Why isn't the expansionboard firmware added by the firmware config tool?
I turned it all off after 30 mins of updating and nothing happening. Now I can't get the Pi to connect to the Duet 3 it just gets stuck on that loading screen to connect endlessly.
I'm going to re-install a clean firmware config on an SSD straight to the Duet 3 and then reinstal the Duet Raspian image on the Pi and start again.
Please provide clear instructions on how to get the expansion board firmware into the /sys folder because uncompressing, copy pasting and then recompressing does not work! Thanks
Charles
