Help, cannot connect via USB
-
Hello, I am new to this and trying to install a Duet 3 Mini+ Ethernet to my Ender 3. I have been following the documentation and started with getting connection then updating the firmware with the USB. I wired up the board and ran through the configuration tool formatted my SD card erasing all the data on it originally. When I started the commissioning step tried to connect to the DWC but couldn't. I then tried to check the IP address and connect my Duet 3 to my computer it does not show up at all in device manager and its not shown in any COM ports in YAT.
Did I mess something up with my configuration? I have attached my config.g file
Did deleting the files on the SD card to begin with ruin something?
Do I need to have the board completely disconnected from the printer for this to work (I unplugged the power supply when I connected the USB).I feel like there is something simple I am missing here but I have gone through my firmware files and the documents again and I don't see anything out of place.

@Jman3 It sounds more like there is a wiring fault, and that there is a short circuit causing the board to not power up. See the following page for troubleshooting steps: https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond
Follow that guide and report back with what works, and what does not.
Make sure you have wired the power supply the correct way around; reversing the polarity at the terminals of the Duet can cause a board failure. Then check the rest of your wiring, and that the board is not short circuiting on any metal behind it, where it is mounted.
Your config.g looks okay. Do you have the rest of the folder structure, eg the config.g (and other .g system files) should be in the /sys folder, and you should have folders /www (the DWC files go in this), /gcodes, /macros etc. /sys and /www need the correct files in them to configure the machine and to be able to connect via the network, the other folders will be empty. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#sd-card-structure for details.

@droftarts Thanks for the reply!
So I have gone through that troubleshooting page. All the status lights on my board indicate that it is working fine. When I plug in the USB I unplug the power supply, should I have the power supply on while I have the USB plugged in? Also the second step of the troubleshooting page "Connect to a PC via USB and look for the port" I thought would apply to me but I can't get my device to show up in the device manager for either of my computers. And for the last step my USB cable is fine and non of the other ports on my computer show the Duet 3, I used this same setup when I initially updated the firmware and it worked as expected. Only after I wired everything up and configured the SD card do I have this issue.
Here is a figure showing the other folders with content in my SD card. the other folders you mentioned are blank per the SD card structure.
-
@Jman3 with the mini 5+ plugged in, rapidly double tap the reset button. does it show up (as a folder) then?
If so, just drag and drop the uf2 firmware file onto the folder/drive that (hopefully) appears -
@jay_s_uk Should it be plugged into the usb and the psu or only via usb? I'm a little worried to reset my board at this point. does that only remove the uf2 and I just have to add it back?
-
@Jman3 the duet 3 mini is pretty hard to break in terms of firmware updates etc. putting it into reset mode won't damage anything and if you don't drag a new firmware file onto it then nothing gets overwritten (but i think in this case that doesn't matter anyway). Its a lot easier than dealing with BOSSA on the duet 2 and duet 3 boards.
You can do it with either just USB power or USB + PSU. Just be aware of ground loops https://docs.duet3d.com/en/User_manual/Overview/USB_ground_loops although i personally have never had an issue (wiring is pretty good in the UK) -
@jay_s_uk Okay thanks, I'll give this a shot today after work.

@Jman3 The third step on the page says:
Connect your Duet to a PC using the USB cable. Do not apply VIN power to the Duet at this point.
So no, it's best not to turn on mains power. The logic of the board will be powered by USB.
It sounds like you may be using a cable that only supplies power, not data, ie it's just a charging cable. Is it the same cable you earlier tested the Duet with?
The SD card layout looks correct, though you're not actually looking at the SD card, you're looking at a copy of the SD card contents in your 'Documents' folder. Would be better to see the actual card contents to confirm it is correct.

Okay good, I'm glad I followed that step about the PSU. Good call on the cable it looks like I had the wrong cable. I must have switched it out since last time and didn't realized the new cable wasn't transmitting data. I should have thought of that, thank you so much!
This might be a dumb question but how would I access the actual card contents rather than just looking at what's in the folder?

@Jman3 said in Help, cannot connect via USB:

You need to take the SD card out of the Duet, and connect it to your PC somehow. This is usually done with a USB adapter, or laptops often have SD card ports. You can also get a micro SD to SD card adapter. Then the SD card will show up on your PC like any other removable drive.
I assumed you had done this when you said:
I wired up the board and ran through the configuration tool formatted my SD card erasing all the data on it originally.
The screenshots you showed don't show the contents of the SD card, they show what is in the Document folder of your PC; it is highlighted on the left hand side, and the path at the top says 'Duet 3 Conf ... > sys' which is part of the filepath to the files on your computer. Have you copied these files to the SD card? Unless you uploaded them to the SD card when you could access DWC, there's no other way of getting them there.

Oh I think I understand, those were the files I put on the SD card originally I just saved a backup on my desktop. The files I showed are the same thing that is on my SD Card, I had copied them over after the configuration. Sorry for the confusion.
-
I did want to ask another question related to this, let me know if this should be its own thread.
After getting my configured SD card and I try to run my first check (Step 3 in https://docs.duet3d.com/en/How_to_guides/Commissioning).
M98 P"config.g"
I send it in the console I don't get anything back that I expect like what is shown in step 3. I also don't see any of my tools or anything in my dashboard.
I also have screenshots of my SYS and Firmware folders, they seem to line up with what I expect from the SD Card Document (https://docs.duet3d.com/User_manual/RepRapFirmware/SD_card)
Does this look right and why doesn't my DWC show any information from my printer?
-
@Jman3 in DuetWebConsole, in the sys folder file list, double click on config.g. This should open the config.g that is on the SD card. Copy the text from there and paste it into your reply. Bonus points for putting it in ‘code’ tags (
</>in the toolbar above where you write your reply)!That way I can see what’s in your config.g

So it looks like the original config.g that was on the sd card didn't get replaced for some reason and I replaced it with my config.g and everything seems to show up on the DWC now but my stepper motors make a loud teapot whistle noise whenever they are activated.
My situation sounds very similar to this thread but non of the solutions discussed there seem to apply to my printer. (https://forum.duet3d.com/topic/29080/duet-3-mini-5-screeching-noise-when-moving-stepper-motors/2)
Any ideas on why my motors have this issue? The motors seem to move in the correct direction and distance they just make this terrible noise that makes me think something is wrong.

@Jman3 Probably nothing wrong, it's just the motor driver is in SpreadCycle rather than StealthChop mode. Some motors whine when in SpreadCycle. You can read about these modes here https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_tuning
For a quick fix, put the drivers permanently in StealthChop mode. Change the M569 commands in your config.g to:
; Drives M569 P0.0 S0 D3 V0 ; physical drive 0.0 goes backwards M569 P0.1 S0 D3 V0 ; physical drive 0.1 goes backwards M569 P0.2 S1 D3 V0 ; physical drive 0.2 goes forwards M569 P0.4 S0 D3 V0 ; physical drive 0.4 goes backwardsThen read the above link to work out if that is what you want!

@droftarts Thank you so much for the help! I'm printing and things are working well!
