asking again, Duet 3 6hc running Klipper?

Re: Klipper on Duet 3 Mainboard
Like I said I know it's old already and if I would have looked into it first I may have made a different purchase decision but i just purchased the duet 3 6hc main board and I don't know RRF yet and really would love it if, even for just now, it worked with Klipper.

Any good news that I Just haven't been able to find yet?

@pm7399 Duet3 mini support is part of the klipper distribution, and I know people worked on Duet3 6HC support for klipper in the past.

Your best source for the current status on this will be the klipper discord.

If you figured out Klipper, RRF will be a walk in the park.

I'm in the same(ish) boat. Purchased a D3 6hc as part of the RatRig bundle with no warning that it wasn't supported. RatOS and Klipper look like a great combo, and had I known, I too would have made a different choice. Interestingly, they no longer offer it as a kit option...

@phaedrux OMG how I wish that were true for me. I am completely lost in it, as a matter of fact I'/m very close to just sending this board back to amazon and trying something else. I really don't want to but I get frustrated with it then I put it down for a minute (a day to a few days) then when I come back to it the amount of frustration I experience is just worse. Keep in mind there's a lot more documentation for every other duet board EXCEPT the 6hc. I can make the connectors I even can understand where to put the wires on the main board but macros and pins have me puling my hair out, even with that configurator website. it doesn't let me add a second z axis but I read something about using m583 (or something) to add it later but WHERE?!?! and HOW?! I mean I'm not stupid by any means but there's just no real step by step instruction for this (that I have been able to find and believe me I have searched) and I feel llike I've been dropped off in the desert with the most expensive main board out there with no real instruction at all and been told good luck! If you know of any said instruction anual written in plain english I'd love to get ahold of it but right now I'm getting really tired of looking at this 3d printer that I can do nothing with.

@oliof with all due respect I have never found discord to be the best resource on anything.

Now many folks use the configuration tool but I never have. To my way of thinking it just gets in the way of learning the GCode commands needed to configure and use a printer. And I have built 9 printers without using that tool.

Why do you think there is a lack of documentation for the 6HC?

If you are not using the CAN bus, setting up an 6HC is pretty much the same as every other Duet board.

I have a printer using a 6HC/3HC combo so I can help you get up and running without a lot of effort.

I'm not necessarily disagreeing, but in this case it's more or less the only source.

If you bought your Duet on Amazon, most likely it is a clone board. Afaik no genuine reseller sells them on Amazon.

Keep in mind there's a lot more documentation for every other duet board EXCEPT the 6hc.

A lot of documentation exists for the Duet 2, because it’s older. I’ve spent the last year updating the wiki for Duet 3. Follow the ‘how to’ guides on the main documentation wiki:
https://docs.duet3d.com/
Also there’s a Getting started guide https://docs.duet3d.com/User_manual/Overview/Getting_started_Duet_3_MB6HC and the hardware page https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6HC_Hardware_Overview

I can make the connectors I even can understand where to put the wires on the main board but macros and pins have me puling my hair out, even with that configurator website.

To understand and for a description of macros, see the ‘Macros’ section here: https://docs.duet3d.com/en/User_manual/Tuning
Generally the configuration tool will create the macros you need, based on the numbers you input, and at least initially you are unlikely to need other macros.

For pins and pin names, RRF uses the physical pin name to define the pin something connects to, and is the same as the pin name on the wiring diagram. Better than a arbitrarily defined number, surely?

it doesn't let me add a second z axis but I read something about using m583 (or something) to add it later but WHERE?!?! and HOW?!

It’s M584 you need to edit in your config.g. See https://docs.duet3d.com/User_manual/Connecting_hardware/Motors_configuring#using-more-than-one-motor-on-an-axis-with-a-separate-driver-for-each-motor

There is one now. 3DMakerWorld.

@pm7399 any luck? I am in the same situation...Can't find a cfg for it

oliof

@b3lmans It looks like @Luke-sLaboratory worked on a config https://github.com/Klipper3d/klipper/pull/5818 but it wasn't merged due to some missing cleanup work.

@oliof Thanks a lot!

Not sure if anyone is tracking this thread. I recently converted 6hc to klipper and got everything working until it came time to connect the tool distribution board and tool boards. As far as I can tell, that setup is not supported whatsoever.

I also didn't know how, if possible, to connect to the SBC with the ribbon cable.

oliof

@gnydick Klipper's CAN implementation does not hold water to RRF's CAN-FD one. Most klipper people I know use USB to connect their secondary MCUs and toolboards, which seems to be better supported on klipper (see https://os.ratrig.com/blog/no-you-dont-want-to-use-can/ for a rant against CAN on klipper). You won't be able to use the 1LC board since the efforts to port klipper to it died from lack of interest.

gnydick

@oliof yeah, i learned that the hard way. I got my entire machine converted, sans the tool boards, and then came the pain. converted it all back.

oliof

I have just been told that development of klipper for the 1LC toolboards has been resumed. So lets see where that goes. People would still need to add a separate accelerometer since klipper does not support LIS3DH ... (edit https://github.com/Klipper3d/klipper/pull/6009/ -- currently misses any documentation about how to get it flashed etc.)

@Herve_Smith I would prefer a constructive and friendly tone in this forum. Especially since you seem to agree that CAN on Klipper is not a good idea.
