Yes, all the 3D printing was done with PLA. I think the reason for the appearance is I used different cameras for the images as well as the flash was in some cases not needed.
During the assembly and printing phases, I didn’t have any real challenges. I guess if I had to name something it would be the lack of accurate instructions with hardware counts and identifying which size screw/bolt went where. Personally, this was not much of an issue for me, but I can certainly see it being an issue.
I was finally able to get some time to work through getting it powered up and the calibration run.
