It won't do DSP, so it'll just do cutting. I plan to use linux/emc2. Maybe later I'll upgrade to DSP. The second cutter will be larger and with DSP and probably higher wattage.
Right now I just have the frame assembled as I wait for the 2.x parts kit. Everything else has been purchased - I hope. I think some of the pre-assembly insertion nut counts are off in the diagram, but I won't know for sure until I'm done.

If you do the same, remember to buy square m3 t-slot nuts (HNTT5-3), since the carrier chain spacing is too small for the cheaper rectangular nuts (HNKK5-3).

I'm hoping this will show up as a collapsible comment. If not, would someone explain how to do that? It's a little weird that depending on how you arrive at a build log (forum vs links at the top of the home page), it will show or hide others' comments. I used the "comment" button to encapsulate the entire entry.
StigOE, thanks for pointing that out. I suppose I didn't notice because 1) the chain end isn't near to the holes in the skin in the assembly and 2) I usually hide all the skins when I'm looking at the machine in Solidworks.
