Yes I did, it took a while, I'm not trying to be modest (god knows) but I actually amazed myself as it's accurate to .0001. The only reason I was surprised is that I didn't spend $5000 on bearings. I spent about $3000 total for the whole machine, or best guess as it took me about 1 year to get the parts and then get motivated to build it. I had to figure out all the electronics and machine all the parts. Luckily I already had a machine shop so I had the tools.
