@oliof Interesting - for whatever reason I had the Duet3 mini as "fewer channels than Duet2" in my head. Thanks for clearing this up.

Update to 3.3 killed Wifi - file (re)location issue?
I have updated my (genuine) Duet 2 Wifi from firmware version 3.2 to 3.3 by uploading the file Duet2and3Firmware-3.3.zip using DWC and confirming the dialog prompt. After the update, I could hear the printer re-starting and going through its homing cycle, but the web interface did not come back. M115 issued through a PanelDue showed the firmware version correctly as 3.3, so the update appeared to have succeeded. M552 showed "WiFi module is being started", even after more than 10 minutes of run time. The Wifi module LED was showing a permanent blue. Cycling the Wifi module state with M552 S-1 followed by M552 S1 did not help.
M587 should show the network list, but it didn't. Instead, I got the message "Failed to retrieve network list: another SPI transfer is pending". I have recently connected an accelerometer to my printer and connected it as described in the documentation, but I have not yet configured the firmware to use it. However, physically disconnecting the accelerometer did not resolve the issue either.
I then tried to reapply the Wifi firmware update using M997 S1, which gave me the error message "Error: M997: file 0:/firmware/DuetWifiServer.bin not found". Examining the SD card folder structure on my PC, I could see all of the firmware files still located in /sys/. Apparently, the file relocations mentioned in the release notes have not been performed automatically - the folder was not even created.
I then moved the firmware over to the new folder manually and reapplied the Wifi firmware update using M997 S1. This finally resolved the problem.
I don't know whether there is some bug in the update procedure or just a fluke - but maybe this will help somebody who ran into the same issue.

RE: waste / nozzle priming bucket - material for lip?
@chanders Hmmmm... Makes me want to check whether I could fit the lower half of a soda can into my printer...

RE: Delta X/Y - um - "undulations"?
Got it. I recently moved the printer to a new place - from one flat and level surface to another - and I didn't bother to re-level it. That came to bite me now - one of the corners (the front right) was considerably lower than the other ones, introducing a twist into the entire frame that was really hard to spot. Re-leveled the feet, now everything is back to normal (pun intended).

Babystepping --> Config: Sanity check
Hi all,
I've found out I need to consistently set an offset of 0.05 mm through babystepping to avoid some first layer issues. In my config, I have
G31 P100 X0 Y0 Z-0.1
In order to make that change permanent, I would need to change the value to Z-0.05 - correct?
(Side question - I'm using a smart effector, is this change likely to cause any issues?)
Thanks

RE: Duet 2 Hangprinter, 5-bar Scara, Polar, Rotary Delta kinematics
@dc42 said in Duet 2 Hangprinter, 5-bar Scara, Polar, Rotary Delta kinematics:
Duet 2 is on the way to becoming a legacy platform
Maybe it's just me, but that's a dangerous statement, unless you're also planning to drop the price of the Duet3 series components significantly. Don't get me wrong, I'm happy with my two Duet2s (Duets 2?) - but from what I can see, Duet has always been at the upper end of the price range anyway. The Duet3 ecosystem is very expensive to buy into. I can only speak for myself, but I would not have invested that much money (and won't for the forseeable future).

RE: Large Format CoreXY?
@deckingman said in Large Format CoreXY?:
I started out with printed mounts but despite the fact that they were thick and printed in PET-G, the combination of heat from the motors and belt tension would cause them to distort after big multi hour prints.
I concur and am able to add further evidence...

@dc42 Thanks for the clarification!

RE: LEDs with 5V fans?
@fcwilt The conversion is done, there is no point in arguing about the fans any more (which I believe should have been made clear by my post). 12V fans would have been possible, but I would have had to add another voltage converter for all fans to my system.

LEDs with 5V fans?
I have converted my printer to an All-Noctua model to combat noise. Since I haven't been able to source small 12V fans, let alone 24V, I've had to convert my hotend fans to 5V, which is mostly working as intended. The only slight problem is that the illumination LEDs no longer work. I assume that the in-series resistors are too high in value even with the 12V jumper on, right? I'm thinking of replacing one of the resistors - would that be an "official mod", and which value should I use?

RE: Duet 2 wifi - Reprap 3 MPU fan thermal control
@jay_s_uk said in Duet 2 wifi - Reprap 3 MPU fan thermal control:
@nobody1982 the drivers only report 3 temperatures. cool (0 degrees), hot (100 degrees) and very hot (130 degrees). Nothing can be done.
@dc42 May I suggest adding this bit of information to the M308 Gcode dictionary page? I was about to post a bug report when I accidentally found out about this limitation...

Failed to collect data from accelerometer
I'm trying to collect data from an accelerometer I connected via SPI to my Duet 2 Wifi. I've registered the accelerometer as described in the documentation, and as far as I can tell, it is recognized. However, when I try to capture some data using the procedure described in the documentation, I get unusable results. Some CSV files only contain
Sample,X,Y,Z Failed to collect data from accelerometer
Others contain a few (max. 124 so far) samples, then the same error message. It appears that it's usually the first measurement taken after powering on the printer that contains some samples, the ones taken after that are completely blank.
I've already checked the physical connections and don't believe there's an issue with them. What would be the next steps to troubleshoot this?

RE: How long dos it take to update to RRF 3.3 form 3.0?
@tkdirp You might have run into the same issue I encountered this morning: https://forum.duet3d.com/topic/23779/update-to-3-3-killed-wifi-file-re-location-issue
