@KenW I do have that macro, and earlier today I accidentally hit the button for that on the PanelDue when I meant to hit Filament Load. That explains it. I'll get rid of that file. Thanks again for the quick help, Ken!

@KenW Sure enough - that file was missing (although all the other files seem to be there). I had intended to check the config files into revision control (like I do for my other printers), but I forgot to do this one. Fortunately, I still had a copy of all the config files on my laptop. I think that copy of the file is slightly out of date, but at least the printer is booting now.

Any idea why that file would disappear? In any case - thanks for the help!

With the help of a friend, I recently built a new printer. It's been working great for several months, but today I was removing a print from the BuildTak plate when all of a sudden one of the fans went to 100% (hotend I think). Then I noticed that the PanelDue was in a "Connecting" state. I went through the troubleshooting steps listed on the website. The LEDs are all looking good (red and green are lit, and status is flashing). So I turned the printer off and connected using YAT via USB. At that point I was able to talk to the Duet, but if I power up the printer again, I get the same non-working state. I don't know where to look next. Any suggestions?

Here's the firmware info:

RepRapFirmware for Duet 3 Mini 5+ version 3.4.6 (2023-07-21 14:09:13) running on Duet 3 Mini5plus WiFi (standalone mode)

I just upgraded to 1.21 and the issue appears to be resolved now.

I have that on my list, but it will likely be a few days before I can get to it. I'll let you know what happens.

I'm also seeing this and have been struggling with it for quite a while. It would be nice to know if this is an acknowledged / reproduced issue. I'm running 1.20 versions of all firmware.

To add a data point to this thread, I'm a fairly new Duet user. I've seen layer issues myself several times. Right now, I'm about halfway through the first layer of a pretty large bed area print, and DWC is reporting I'm on layer 9 of 86. It should be layer 1 of 90.

Thanks for the suggestion. I looked, and found that there were two T commands right before my starting script (I'm using Simplify3D), and one immediately after, but no more (see below). This is very odd.

The firmware is version 1.19., and I'm using just an E3D Titan Aero. This is on a Hypercube Evolution that I just finished building. I've done a few prints successfully, so this definitely surprised me.

I was about 10.5 hours into a print. I came into to check on it and all looked good but on closer inspection I found that it was not extruding. Then I noticed that the hot end temperature was back to ambient (I forgot to look to see if it was showing as active). I was puzzled, so I looked at the G-Code Console, and found this (with the message at the top continuing until I cancelled the print). Any idea what happened?
