cannot connect to duet 2 Wi-Fi or board

[droftarts]

@Phaedrux @Blunt2007 the dual driver expansion only works on the Duet 2 Maestro, you have a Duet 2 WiFi.

The last config.g I saw of yours has the drives mapped as:

M584 X0 Y1 Z2 E3 ; set drive mapping

That means you are using 4 drivers. Unless you changed it to put, say, one of the Z axes motors on driver 4 (marked E2), there should still be a spare driver on the board, spare heater output and temperature sensor input. So you may not need additional expansion.

See this page for external drivers: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external

Sorry for the bad info. I should probably hold off posting when on the cold meds.

[Blunt2007]

@droftarts for my dual extruder can you check the wiring on this for the drivers I got two question marks . Can you help me with the wiring upper left of the picture in my writing lower right is the motherboard Hope you can help me to get my drivers up and running 2209 and the pin has been cut for you UART

[droftarts]

@Blunt2007 Sorry, I can't advise on how to wire this combination of boards. However, see this thread https://forum.duet3d.com/topic/34500/using-expansion-mini-2-on-duet-2-ethernet for someone who has done the same thing.

@droftarts okay thanks still working on it meanwhile I'm trying to get the 3D printer working turn on board and tried heating up bed and got this fail statement what's causing this can you help still having problems trying to connect to it with Wi-Fi and it won't connect try using USB not working still having the same problems over and over
With the Wi-Fi

[oliof]

@Blunt2007 for the bed heater error, you need to PID tune the bed to get rid of this error. Run M303 H0 S70 and save the PID tune values; see https://docs.duet3d.com/User_manual/Reference/Gcodes#m307-set-or-report-heating-process-parameters

Okay, let's get this board exchanged under warranty. 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.

@droftarts I got my new board and tried connecting with USB and it would not connect but when I push the reset button it connected but I but I'm not able to connect by Wi-Fi so I upload it (runonce.g) to the system file and I was able to connect to Wi-Fi and it comes up with my duet is it possible that I have the bog rate set wrong I have it set at 9600 can you tell me what you guys set the bug rate to by the factory maybe that's why I cannot connect by USB

[droftarts]

@Blunt2007 Glad you got a new board, sorry you're still having problems.

Are you using YAT to try and connect, or something else? 9600 baud rate should be fine, it's what I use, see second step here https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-3-connect-to-duet
9600 baud (bits per second), 8 data bits, Parity none, Stop bits 1.

Is the WiFi working better this time? Does it stays connected, and reconnects, if you turn the Duet off and on?

Ian

[Blunt2007]

@droftarts All my settings are correct and I still cannot connect USB to pontephase or yat. So far I'm able to to connect to the Wi-Fi hopefully sometime soon I'm going to upload a new profile to the new board I'll let you know if I lose Wi-Fi or not

[Phaedrux]

Do you have another computer to try with?

[Blunt2007]

@Phaedrux Yes I tried it with another computer and I still couldn't connect by USB using yat or pronter face

[droftarts]

@Blunt2007 One more thing to try; do you have a USB hub, either powered or not powered? If so, try connecting through that.

At least the WiFi is working on this one!

Ian

[Blunt2007]

@droftarts I do not have a hub and I uploaded a profile to the board and it's disconnecting from Wi-Fi and then reconnecting and then disconnecting and then reconnecting and disconnecting where before I loaded the profile it wasn't doing that it was staying on Wi-Fi. And not everything is correct such as my fan for my hot end is not coming on and the printer is moving real real real real real slow do and when I load a model into the printer now when that has worked before that is even going even slower. On the tuning videos that I've been watching they use USB to type in code to be able to change our parameters by g-code My USB is not working with the printer what do you suggest

[droftarts]

@Blunt2007 Okay, I think your problems are:

• WiFi disconnecting and reconnecting all the time
• Fan not coming on
• Printer moving slow
• Entering Gcode commands
• Still can't connect via USB

WiFi disconnecting and reconnecting all the time

I'm going to need to see a full M122 output, as the Network/WiFi diagnostics are at the end. It could be one of a number of reasons, like poor WiFi signal, congested WiFi channel, aerial not connected, router band switching... there's lots of reasons. If you are not having to set the SSID and password each time with M587, then it is probably solvable.

When you can connect via DWC, click on the 'Console' menu option, and type M122 where it says 'Send code...' in the middle of the screen. You should get a response in the area below. Copy and paste that into your reply.

Also see this troubleshooting section: https://docs.duet3d.com/en/User_manual/Troubleshooting/WiFi_troubleshooting

Fan not coming on

This could be configuration, or wiring. Did it work before? Is it the hot end cooling fan or the part cooling fan? Post your config.g. Do this by going to the the System menu in DWC, right-clicking on config.g and either 'Edit' or 'Download' File. If you edit, copy and paste the contents of config.g into your reply. If you download it, you can drag and drop the file into your reply.

To check the wiring, you could plug it into the 'always on' fan header (see the wiring diagram here). If it works, great. If it doesn't work, check the fan fuse, which is the 1A blade fuse on the board.

Printer moving slow

If you've posted your config.g (see above), we can see what speeds you are using; these may just be too low. Slicing software has a bad habit of changing your settings. Open the Gcode file (in a text editor) and check the first 50 lines, and see if it sets any Gcodes for speed and acceleration. Look for any line that starts with Gcodes M201, M203, M566 or M204. If you find them, post that section of the Gcode, along with what slicer software you are using.

Entering Gcode commands

I'd fix the other problems first, particularly the 'moving slow' one. When you want to send commands, you can send them in DWC from the 'Console', like how you sent M122 for the WiFi problem. It does that same thing as sending them over USB.

Still can't connect via USB

I really don't know why this isn't connecting. Have you tried other USB leads? Many USB leads are just for charging, and don't have the wires inside for carrying data, so you may have to try a few. Look for cables that are a bit fatter, they may have 4 wires rather than 2. Otherwise, there's very little difference between them, just try all the USB cables you have!

This generally looks fine. -32dBm is a good, strong signal. Does your Duet have an external aerial?

A possible problem is that it is set to channel 0; I think this is reporting incorrectly (there is no channel 0, only 1 to 12) as you are on a slightly older version of the WiFi firmware, 1.26.

As you are using the latest RRF version 3.5.0-rc.2, you could update the WiFi version. From https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.0-rc.2 upload the "DuetWiFiServer.bin" file. You will need to input your SSID and password again, using the "runonce.g" script.

Also make sure you are using the same version of DWC as firmware. Check by looking at the Setting > General and Machine-specific tabs. If it is not the same, upload the "DuetWebControl-SD.zip" file from the firmware release.

Then send M122 again, and see what channel you are connected on. If you don't have an external aerial that plug in, the following might be the cause of disconnections:

Particularly if using channel 1, change the router WiFi channel. Duets with onboard WiFi antennas may be more susceptible to interference from the Duet itself at this frequency. Try channel 6 or 11.

@droftarts every time I try loading a m 420 bad leveling it kicks me off. And then I got to restart my browser to access board again and then when I try entering m420 bed leveling it kicks me off again I'm trying to get this on there because the screen is coming up with a m 420 does not exist. I got the fan working that was wires were reversed fan is working now now I'm trying to get my BL touch to work

[oliof]

M420 is not supported in RepRapFirmware. Are you maybe running G29 or G32?
