Large Format Dowell to Duet conversion
-
@phaedrux I thank you
I will check / change all that. Yes they are just simple end stops. Only two wires coming from them.
The thing I really cant work out is how to wire the on-off switch relay board as per the question marks that come off the wires coming out to the left of that relay board in my âschematicâ above. It needs a 5V in and a signal input from the duet. Please advise!
Sorry about all the questions just the best I have made before is some resonant LED circuits and a PC.
Many thanks

I'm not super savvy when it comes to relays etc but I think what you want is an external 5v supply for the relay to power it, and then the signal would be coming from the duet using the PS_on function M80/M81 see here: https://duet3d.dozuki.com/Wiki/Power_Wiring
Where does the current printer get the 5v for the relay from?

Nothing like diving into the deep end.

undefinedHi dear @Phaedrux and @dc42
Thanks so much for your help! I've covered your last point re the power relay in item 1. I then have a couple more questions before I power this thing up and try and get some configurations tested if you could help with those too please:
- Regarding the signal cables and 5v cables to the power relay. To answer your question: The 5v and signal cables were connected to the old motherboard. In the article you linked me to it says:
'If you are using an external relay to control mains power to the PSU, you can wire either the +5v or +3.3v (depending on what your relay requires) outputs from the duet in to the positive terminal of the relay, and wire the ground terminal of the relay to the PS_ON output on the duet. If you are using a mechanical relay and it does not include a flyback diode of some sort, you will need to wire one in parallel with the relay signal.'
Please note the 5v pin next to the PS_ON is an input and as it is has a diode in series with it will not output 5v. If you need 5v to power a relay of some sort you need to use the expansion connector pin 1 or the 5v pin on the vfan jumper.'
I can't seem to find 'vfan' jumper on the Duet 3. Please advise?
- I have connected the other wires to the ports listed in this diagram:
- undefined Green Machine Wiring Table
Do you think the Noctua good in the PWM lazer three pin connector?
Do you think the thermocouple is okay with the cable running alongside the extrudor motor cable to the gantry? Both bed and nozzle thermocouples are in the daughterboard of the expansionboard.
- Is there any-way to make a firmware config using the online configurator that has more than one z axis or do I need to edit the code in Visual Code Studio after I make a config file just adding those extra motors to the list?
4a Is there any way to use the Duet Web Control (DWC) to monitor the print live over webcam?
4b Using Cura as a slicer, is it possible to delete a part during printing to move onto the next one as with Octoprint or is it best for me to use Octoprint for the webcam monitoring and part deleting? If so I will either flash the configs straight to the mobo and run octoprint to print through the usb or set the raspberry Pi up with dual boot: The Duet Rasperian image for setting up configs and then the Octoprint image for printing that way.
- The only other thing is working out how to connect the screen at the front but it's not a duet screen so I am not going to worry about this till after I have the printer working again.
Many many thanks
Charles

Hi gents, so sorry so many questions but here are some more re firmware config:
- Heaters:
Sensors:
I have the daughterboard plugged into the expansion board for the k-type thermocouple for my bed and nozzle. Which of the options should I choose? I canât tell from the list.
- Z probe config
I have my 3D touch plugged into the IO2 port of the expansion board but the config options for the âz probeâ and BL touch
It wants: PWM Control Channelâ for BL touch. Should I use this as the only assigned option for the 3D Touch?
-
@charles-fraser in the IO Mapping page:
EDIT: I see that the daughter board is plugged into the EXP3HC. the config tool doesn't support that directly, so you will need to edit the config.g file. In the M308 commands, change spi.cs1 to 1:spi.cs0 and change spi.cs2 to 1:spi.cs1.

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.
@charles-fraser said in Large Format Dowell to Duet conversion:

Do you mean the 5v or 12v connection? Either may work. At 5v it would spin slower.

Provided it's shielded it should be ok.
@charles-fraser said in Large Format Dowell to Duet conversion:
4a Is there any way to use the Duet Web Control (DWC) to monitor the print live over webcam?
Yes, it has a window where the feed from a webcam can be displayed. Personally, I use a Pi zero W with camera module running MotionOS to display a live stream.

4b Using Cura as a slicer, is it possible to delete a part during printing to move onto the next one
Yes, as long as the objects are labeled in the gcode the DWC gcode viewer plugin can be used to cancel objects.
@charles-fraser said in Large Format Dowell to Duet conversion:
is it best for me to use Octoprint
No, using octoprint isn't really recommended at all because that would mean using octoprint to stream the gcode over USB which has a number of limitations.
If you're using the Pi with the Duet as you have connected in your photos, you would be using DuetPi anyway.

@charles-fraser said in Large Format Dowell to Duet conversion:

The only direct connect screen compatible with the Duet is the PanelDue. The Pi itself can use HDMI touchpanels and display the Duet interface there.
@charles-fraser said in Large Format Dowell to Duet conversion:

Take a look at these limitations. https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations
If possible, try to connect the probe to the same board that has the Z motors, though it is still usable otherwise.
The config tool is a bit limited when it comes to more advanced configurations, so you may have to do some manual setup editing the config directly. The BLTouch needs a servo control pin (out), and a trigger pin (in), along with power and ground.
Here's an example of it being wired up. (ignore the fact that it says io_3 and io_4 at the same time.)

Other options exist. RepPanel, RRFDisplay as seen elsesewhere on this forum; the BTT TFT support for RepRapFirmware improves roughly on a week-by-week basis. These are all open source. The closed source FlyMAKER screen also is available.
Personally, I do not regret buying the PanelDue. I'd prefer an 12864 controller on Duet3, but haven't put the RRFDisplay to use yet myself.

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?
Iâve 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 canât work out what it means. What does it mean?
-
ENDSTOPS: How to setup z end stop. Itâs a 3D Touch with a little switch wired into it? I canât turn on the âEndstop type > switchâ in the config menu. â¨â¨â¨â¨3.1 Is âlow endâ when itâs at the furthest point from the extruder or closest?
3.1 Is âlow endâ when itâs 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 âTemp 0â 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 âconfigâ and âbedâ 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 canât 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

p.s: I tried it with 4000mA per nema 23 and now when I press âhomeâ 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
