Duet 3 Mainboard 6HC - initial production run.

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.

@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.

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

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.

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.

The "Hardware overview" of the Duet 3 says "Ethernet for future expansion", I am guessing that this is a typo and the board has an ethernet connection not using WiFi?

deckingman

@fotomas The RPi has an RJ45 Ethernet which is what will be used for the web server etc. So my guess (and it is just a guess) would be that it's not typo but is indeed an additional Ethernet connector.

A Former User

@deckingman
You are correct the pi 3B+ also has wifi

@fotomas

I think you would benefit from reading and analyze and digest the documentation in greater detail, as guessing is the mother of all F******s

The ethernet port has been covered earlier in this very thread..

The Ethernet connector is there for 2 reasons:

For possible support of EtherCat in future.
We have a small number of OEMs who use Duet 2 in print farms, where one PC uploads GCode files to multiple Duets. They will need to replicate this with Duet 3. So there will be the possibility of running the Duet 3 in standalone mode with a local SD card and no RPi. Then the Ethernet port will be used to upload files, send commands and get status, just like the Duet 2. But we haven't yet decided whether to fit the SD card socket as standard to the initial production run.

gtj0

@dc42 If you decide to not populate them, will the Duet3's be field upgradable if we decide we'd like that functionality? I.E. Is it just a matter of adding the magnetics/jack and the sd card holder?

T3P3Tony

@deckingman yes 4A but RMS now. David has tested over 4A RMS but I will keep the claim to 4 for now until we have done more testing
