Still getting the same issue. This is the message I get as soon as I connect via usb:
RepRapFirmware for Duet 2 WiFi/Ethernet Version 2.03beta3 dated 2019-03-25b6
No SD card present
WiFi is disabled.
RepRapFirmware for Duet 2 WiFi/Ethernet is up and running.

My printer sat idle for a little while and now it will not connect to the network. When I connect via USB I get a "no SD card present" message. The SD card works when i connect it directly to the computer however.

@deckingman:

Works for me. Maybe it got fixed between your post and mine?

Weird…I still get a 404 when I try the link.

I just want to report that the github link on this wiki page is broken. https://duet3d.com/wiki/Updating_main_firmware

I did a bit of research and came across this https://forums.ni.com/t5/LabVIEW/How-to-monitor-a-UPS-by-serial-port/m-p/3318648/highlight/true#M972416

At least for the cyberpower brand units mentioned, they send just send simple on/off signals on the control lines for low battery and AC power loss so we could presumably trigger something to happen in each event.

The way I see it, if you just want to stop a print when power goes out M911 works. The benefit of a ups would be the ability to print despite the power going out (especially useful if you only lose power for a couple of seconds/minutes at a time). The most useful situation I can think of would be as follows:
1. Power goes out, printer keeps printing from ups power.
2. Power comes back, printing continues. Otherwise:
3. Power stays out, ups reports battery situation to duet.
4. Duet pauses print and shuts down printer before ups battery runs down.

There seems to be a black spot on my E0 driver:

But I don’t see any damage on my Y driver.

What would damage to the driver look like? Input voltage is only 12v.

Help! My duet just flashed an over temperature shutdown on drivers 3 message. I restarted it and now it won't extrude. When I hit "extrude" in DWC the motor makes a squeaking noise but then nothing happens. Did I break it? I was printing earlier today and the only thing I've changed is to set up mesh compensation.

Update: I left it alone for a while and came back to discover that I can't move my Y axis either. When I try to home Y it makes a grinding noise and then stops.

Just a quick update, I think I solved the issues. I discovered that I had the wrong thermister B value for my hotend. I fixed it and ran a PID tune and now I'm still getting alot of underextrusion but it doesn't stop and start like before.

@whosrdaddy:

Does it extrude when you command extrusion from DWC?
If yes then the next question would be, which slicer are you using?
If it is Cura, you must use absolute extrusion mode (Duet uses relative extrusion mode by default)

I can extrude from DWC and it seems to work fine. Using cura with relative extrusion mode.

I got my XYZ set up and working but I am having issues with my extruder. It will extrude perfectly for a few mm and then it will stop for a few mm (XY movement still occurs but no extrusion) and then start extruding again for a few mm over and over. I thought maybe it was a torque issue (non geared mk10 extruder) so I tried increasing current and reducing microstepping but issue persists. Does anyone have any other ideas as to what might be wrong? I have an e3d gold hotend.
