Can no longer connect to my Duet 2

plasticfactory

My daily use printer will suddenly and simply not connect to DWC. I follow all the basic connection steps, am tethered by USB, but to no avail. Quite literally nothing has changed between now and the print I finished this morning. It's a Duet 2 running 3.0 firmware, e3d Toolchanger hardware.

Where should I begin troubleshooting?

plasticfactory

It miraculously started working again, like nothing had ever happened.

And now it won't connect again.

droftarts

@plasticfactory Does it connect on USB okay? If so send M122 and post response. I’d probably start by removing SD card, backup all files, and try a new SD card.

WiFi or Ethernet?

plasticfactory

Back to it randomly not working. It's wifi. It connects via USB fine. This is an intermittent problem I have had for a long time (not just with this machine) and it's beginning to turn me off to Duet, which is unfortunate for a number of reasons. The "random" nature of it all is very frustrating.
EDIT: I suppose I will try a new SD card... Will report back someday.

plasticfactory

Printer is working fine again, no changes. Still going to try the SD replacement to see if it removes this persistent problem.

Phaedrux

Can you provide the results of M122 when it's having issues?

plasticfactory

@phaedrux Will do. Happened again today (new SD). I just waited about 30 minutes, and things were good. Next time it happens I will try this and report back.

A lot of bug fixes and improvements since 3.0. I suggest you update the firmware, etc.

If you still have access to DWC. Upload these zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 to verify the firmware has been applied.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip

That will get your firmware and DWC up to date. The reason for doing 3.0 again is to ensure all required files are present first.

You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x

You may need to make some slight changes to the config.g going past 3.0. You can check your config.g for syntax errors by sending M98 P"config.g"

plasticfactory

@phaedrux Thanks, I got everything updated and haven't had any issues so far. I do have a couple of questions (and please tell me if a new thread is preferred),

where can I view a visual representation of the height map with this current DWC version?
During a print I can only make modifications to whatever extruders are inactive. For example, I am currently printing with Tool 3 (Extruder 2), and can only make adjustments to E0 and E1. Not sure if that's just how it works now or if I have something configured wrong.

It now exists as a plugin that you can enable. Check the General > Plugins tab.

Can you be more specific? What are you trying to adjust? How?

plasticfactory

@phaedrux I mean simply increasing/decreasing extrusion rate, using these sliders:

Phaedrux

Can you share your config.g?
Also confirm that your firmware has been updated to 3.2.2 and that the DWC version matches as well.

@phaedrux Firmware has been updated to 3.2.2 with matching DWC control.

Thanks for the help.

dc42

@plasticfactory I have the same thing on my tool changer. We will investigate.

dc42

@plasticfactory you needs to click on the Change Visibility link just above the extruders, then you will find that you can enable the slider for your third extruder.

plasticfactory

@dc42 Thank you, that did it.

Unfortunately the connectivity issues popped back up even after updating. Anything else I can try?

Phaedrux

Can you connect via USB terminal when it's unable to connect and gather a M122 report? If you then send M552 S1 what does it say?

plasticfactory

@phaedrux Just so I totally understand, even if I can connect long enough via wifi to run M122, should I still run it while connected through USB? It basically drops connection over and over, but usually between 1-2 minutes of it working fine.
