Duet 3 Mainboard 6HC - initial production run.

@calvinx I'd say mainly personal preference. I run Arch Linux on all of my machines. I like the concept of a rolling release and having the latest version of all packages. On RPi 3B(+) there is even an aarch64 image which let's the ARM A53 use its full potential (unfortunately there is no upstream kernel support for RPi 4B yet so this still has to wait).

Tony, there is a bit of a conflict in the documentation https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview.

The picture of the boards has a graphic with the words "6x stepper drivers rated to 4A peak". But under "Features" the words say "Six high-current advanced TMC5160 stepper drivers: SPI controlled will all the latest Trinamic features. Maximum motor current 6.3A peak per phase (4.45A RMS)."

As DC ran the thermal tests on an expansion board at 6.3A, I'm assuming the "4A" in the graphic is incorrect.

The Freescale iMX6 platform is well supported in Linux. I wrote some of the device tree and driver stuff for it.

Not criticizing the choice of C#, just curious. I haven't done any C# development in about 10 years so I'll have to see what .NET dev tools are like for Linux these days. Hopefully there's an Eclipse plugin.

You may want to take a look at Mono for .NET. Microsoft has been putting a lot of effort into bridging the Linux gap in the last few years.

Yeah, I've used Mono for running .NET assemblies for quite a while. The Microsoft .NET Core for Linux is also working fine. I just can't stand Visual Studio. Actually, the Acute plugin for Eclipse is at least workable for editing C# and I just built the DSF for both arm and x86_64 so maybe it won't be that bad. I might not even need to modify it for the Wandboard, just set the device paths in the config.json file. We'll see.

@gtj0 There is also MonoDevelop as an IDE. And the apps are actually based on .NET Core and as such do not need Mono (if anyone needs more recent packages of .NET Core on Arch Linux I have them in my Dropbox ).

EDIT: one of these days I need to look into finding a good Language Server for C# and then I can develop in neovim.

I think a connector/plug pack should be included as a mimimum, if not included in the duet 3 anyone who has experienced what is included after purchasing earlier iterations of the duet ecosystem is going to feel mighty cheated to have to go source connectors and plugs themselves after shelling out for the duet 3 and an sbc

Don't forget that .NET supports other languages apart from C#, in particular F#.

Then there is J# and VisualBasic... Wasn't there also a Q#? Way too many Sharpies. If I have the choice I'll stay with my beloved Go, though.

EDIT: it seems neither J# nor Q# (actually for quantum computing) are supported by .NET.

MonoDevelop doesn't support .NET Core projects using .csproj project files. It complains about the project file not having a ProjectGuid.

BTW, I have a Wandboard loaded with Fedora 30 and SPI support running the DSF. No changes to the DSF needed but then I don't have a Duet3 board to test with

Thanks Ian - its fixed now

@calvinx Thats the plan - just see if we can get them sorted in time for this initial batch.

Dumb question: what voltage do the 5A OUT1-3 receive, the ones intended for "extruder heaters or similar?" Is it just VIN?

Still showing 4A here https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview

It does so for me. Which versions of MonoDevelop and .NET Core do you use? I have MonoDevelop 7.8.3 and .NET Core 2.2.401 (with 2.2.6 Runtime).

Thanks for the clarification.

Whats the plan to cater for those that purchased the initial batch if you cant amass connectors and plugs in time ?

@t3p3tony Tony how is the pr-orders going for the first batch I need to order one but won't be able to till the end of this week?

.NET Core is the same but MonoDevelop is 5.10.0 which is what's packaged for Fedora. Upgrading to 7.8 fixed it. Thanks Manuel!

Also curious. I'll order one, just to support you guys, if there are enough left to stand a good chance of the order going through in this first batch.
