Good luck! I am about 2 months into my 2.4 R2 build. My kids are younger and life is busy, so I'm lucky to get an hour or two every few days to chip away at it. I have everything but my panels on and wiring is done, so I should be powering it up soon.
The build is pretty straightforward. The only real gotcha that I ran into was missing the occasional printed part and not paying enough attention when grabbing 16T and 20T pullies. My generic cable chains were too short, but other than that all the parts fit exactly as intended.
