OK, this is a bit amusing since I just purchased a workbee, have a duet wifi spare and a bunch of time. While waiting on it to show up here i'm spending some time creating a post processor for Bobcad/cam that'll work with the duet. Shouldn't be too terrible to make it work right.

Good news, went through the erase and upload technique and am now on current code. Apparently for some reason things got locked up and wouldn't do the upgrade with that alpha version of code. All good now. I did go through the levels of updates one at a time just to verify that the system is working as expected. Went to 1.19.2, then to 1.20 and finally to 1.21RC4 all without any further trouble.

just an addition to this but it was completely worth the bit of pain working through this, the new code is substantially more user friendly and several items i'd been fussing with are resolved now.

I uploaded the lap4e.bin to replace the version that was on it although the file size was the same (hard to tell since it's just listed in KB rather than in bytes).

Went through the upload to 1.19.2 again and same result.

Here are the versions on it now:

Firmware Name: RepRapFirmware for Duet Ethernet
Firmware Electronics: Duet Ethernet 1.0
Firmware Version: 1.19alpha3 (2017-05-09)
Web Interface Version: 1.19.3

The sys directory has these contents:

When I send the M997 I get a dialog box on the paneldue saying Updating main firmware. there is a red X in the top right corner of that box that can be selected but it never goes away or seems to attempts a reboot to the new firmware. If I press the red X, the dialog goes away but the firmware is obviously locked up since issuing any other commands on the paneldue doesn't yield any output.

As far as the instructions go, I'm assuming that since this is the ethernet version that the filename DuetWifiFirmware.bin should be replaced with DuetEthernetFirmware.bin. Other than that I followed this procedure and have tried method 1 and 2.

I am trying to upgrade this (I think it's the version that was shipped to me when I bought it) and went in via the web UI following the procedure. It all looks to go as expected, uploads the file, asks if I want to upgrade firmware and then a progress bar which looks to complete. I then disconnects the web interface and I can't get back into it until I reboot at which point discover it's not burned the new firmware to the board. I also have a paneldue on this and get the firmware updating message which never seems to go away until reboot.

I've also tried the M997 S0 from both the web interface and the paneldue with the same results.

Basically it doesn't seem to be programming the board even though I can see the file in the sys directory.

I've tried the 1.19.2 and 1.20 version with similar results.

Any hints on a way forward would be appreciated.

I machined mine at 55 and about the only thing I noted is having to be a bit more careful about anything mounted to the vertical tower and staying clear of the mounts (how. Do I know this,..it wasn't pretty). Larger seems like a good notion though.

Think a larger size would be useful if this got extended to two hot ends in the future.

Quite interested in this as well. Wound up machining a similar setup out of AL but without the electronics. Works rather nicely with the rod ends absolutely parallel.

So, first off I'm extremely pleased with the Duet Ethernet's speed. The thing is amazing in how fast it loads code and generally operates.

The problem I ran into is most likely some wiring issue. Was running a print that was into it around 4 hours and suddenly the duet ethernet and paneldue shut down as if someone killed the power but I've got a light wired into the same PSU and it didn't even flicker. After a few minutes it came back up.

My PSU is an ATX PSU with the 12v going to a small bus terminal strip which has the lights (small LED strip) also wired to it. I'm only running the hotend through the Duet and it's drawing around 120W as measured at the outlet (the PSU is 400W). The PSU was cool to the touch so it's not overheating. Just looking for where to troubleshoot this to find the issue if anyone has a suggestion.

I've got kind of the same issue, the SD card in PanelDue doesn't mount on startup and when I do mount it via the web interface, it gets stuck in "mounting". I can get around it by clicking refresh in my browser but I can't find any combination of buttons to view the flash card until I fresh the page. Once done it actually works fine but considering that this card is intended to be removed and inserted fairly often (or at least that's what I plan on using it for as uploading a big gcode file via the web interface is just a tad slow), it's a fair bit of hastle.
