@o_lampe I like opensource, because it brings so many questions which finally moves things forward.
Everyone likes opportunity...

Believe or not, people in a lab I work can populate similar things without reflow or paste mask. Yes one board takes one day... but the costs can worth for me and others.

Regarding BOM, one piece is not 100% efficient, but there is a lot of space in the original's cost for such inefficiency. Two boards are a lot better and three are 90% efficiency of 10.

I am unsure if it is fair to share my BOM here. This is opensource project (thank you!) but I have respect for authors and they need our support not concurrence. So no clones, no parallel kickstart actions... BOM costs and manufacturing costs are questionable.

I will have BOM costs done in a month or two (I have other priorities). Then I can share some numbers.

Now I hope others could share my passion.

@t3p3tony I can confirm the issue fixed in commit d157c83 (https://github.com/Duet3D/Duet3-Mainboard-6HC).

Just for others, I see warning (see below) when I open the project but the schematic is fine now.

Warning maeeage (ignore it) :
This schematic was made using older symbol libraries which may break the schematic. Some symbols may need to be linked to a different symbol name. Some symbols may need to be “rescued” (copied and renamed) into a new library. The following changes are recommended to update the project.

Thank you t3p3tony, good job!

PS: The kicad version I use is current version for Ubuntu 20.10 .

Hi,
I see problems with the BAT40V symbol.
Is this symbol really defined in kicad symbols - "Diode.lib" ? I do no see it there and in DUET3.lib neither.

Kicad: v5.1.6+dfsg1-1 release
Kicad symbols: 5.1.6-1
Duet3-Mainboard-6HC: commit edeb675
