Anybody using a Duet board with a Klipper SBC?
-
Thanks Luke, one more question if you don't mind, I am using the Duet2 Wifi stall detection for my CoreXY x/y homing. Will this still work with Klipper?
As a side note: I wonder what kind of support Duet3 provide for customers that use their boards with Klipper rather than RRF. I guess that kind of support will come from the Klipper side.

Not sure. Haven't implemented it on the D2. Check out the klipper discord and other for more info.
Not sure on the other q

Also, when using a Duet board with Klipper, is there an option for a user friendly touch LCD? (PanelDue or another).
I think we've seen Nero3D use PanelDue on stream, but can't say for sure it was with klipper but I do believe it is supported. However I'm partial to PITFT50 and CTP40 screens for the Pi - both were around $30 but have gone up a bit.
(Currently using OctoDash, pending the move to klipper but PITFT50 and CTP40 work great, and can VNC to the same interface, supports thumbnails. Love it, hoping klipper can match it)
Also yes, I'm hoping to settle for converting ender 3 to corexz instead of dreaming about building a switchwire. Then again, who knows, maybe I'll fall in a got of gold..

I WAS running my RailCore with Duet2 ETH+Duex5 with Klipper firmware on a SBC. (Ethernet port on Duet2 was flakey)
Most of it is pretty easy to configure, Issue I had default power setting for the heated bed is 1, so my heated mat has come partially away from the plate.
Been struggling for a while with Klipper, quality was lacking, even though I had gone through all of tuning etc, my parts looked poor compared to running with RRF.I found the implementation of the BLTouch hit and miss with klipper/Duet
The nail in the coffin for me is when I needed to be able to do a 4 point probe which allows for aligning the X rails on the RailCore. Minimum probe points in Klipper is 9.
I asked is the bed_mesh routine could be changed to allow for a 4 point and was told it was a new feature, ask in Klipper discord. etc etc
In a nutshell was told to jog on.Have now come back to RRF.
So now I have just bought a Duet3 Mini and a toolboard which I will use to upgrade the RailCore and then use the Duet2 and Duex on a Beta printer I am building.
The Voron V0 and 2.4 300 will stay running SKR's and Klipper.
With Klipper you no longer have to run Octoprint, some people have worked hard and there is A really nice console using Moonraker backend with MainSail or other front ends.The RailCore is not a cheap printer to build and it deserves to have Duet boards fitted.
That is why the CroXY and Annex builds specify Duet boards.For clarification, this is my opinion and experience, YMMV.

Interesting - not sure what issues there were with your heated bed. Haven't had any weirdness like that.
as for the aligning of the x axises, not sure what you're going for, but there are several routines for adjustment, what were you looking to do? is there a baked-in RRF gcode for it?
as for annex specifying duet boards, recent BOM's switched from SKR -> Fystek S6 https://docs.google.com/spreadsheets/d/1oXqvtk06rsHcD06igabW3sL7RkIG_uLstGmKU9D9Gv8/edit#gid=1410625863
CROXY specifies Duet Boards.
I hope to have definitive comparisons to help out with these discussions and raise the bar for everyone!

Here is a good Klipper introduction video by the Voron guy. One of his Klipper based printers is based on a Duet2 and has a functioning Panel Due (Around 15:45 time mark).

you can add [?|&]t=945 to the url to jump to the timecode in seconds or "use the copy video url at current time" option form the context menu in youtube https://youtu.be/iNHta6zljoM?t=945

@Luke-sLaboratory any chance you can send me your config file ? Duet 3 mini should be close enought to duet 6hc.. Im still trying to find the stepper address for the 6hc board.

Just wanted to add that besides input shaper RRF has more on it's road map:
https://forum.duet3d.com/topic/20602/reprapfirmware-road-map-q1-2021?_=1615749405350
"RRF 3.4: the focus of this will be the motion system. We will be looking at input shaping, S-curve acceleration, better cornering algorithms, and other mechanisms to improve print quality. "

Hopefully that release will significantly benefit my Duet2 Wifi, no extenders, no SBC printer. The recent releases seem to be 'for other people'.
BTW, looking more into the Klipper, its two tiers architecture of an SBC tied to heterogenous 'dumb' I/O slaves seems to be simpler, more open, and more promising than the Duet's 3 tier approach of a SBC, a proprietary smart controller and proprietary slave controllers (extenders, tool boards, etc). I like it more and more, but don't have yet real life experience with it.

I tested klipper on duet WiFi and deux5 this weekend. I run true bed leveling with it quite fine and the input shaper does magic. The UI is not great compared to duet but I might stay with it because of the magic the input shaper does. Wish I could add a photo here easy and I’ll show the huge difference.
Managed to crash my Z axis during setup so I got some Z banding now but I can’t blame klipper for a user error

copy n' paste and drag n' drop should work for pictures, there is also the upload image icon on the toolbar (second last)

I hear this Is a criticism often levelled at Klipper. By no means an endorsement, but I did find this recently: https://github.com/Stephan3/dwc2-for-klipper-socket

@gaweyo It was a bit easier from a pc than from my phone
I have some issues in the Z axis after a crash during config but it still shows great improvement of ringing in the lower print with input shaper enabled. Upper print is without input shaper. Both are done with 1500mms accleration increasing each 5mm up to 7000mm/s accleration and the print speed is 100mm/s.

Improvement is very significant. Does the printer sound quiet or more graceful at high speeds?
-
@minim take a look at fluidd - it's excellent.
-
@zapta yeah it does actually. I don’t think I will switch back even if I hate SBC
