Apologies, i have not bought it yet! Just what i planned to use. Your build looks like its progressing well, i was looking to pay nearly £700 for the ballscrews but my guy in China is doing them & the supports, mounts etc for $217 delivered!

Where do you get your fixings / bolts from? I commonly use ACCU Group, hundred of sizes, heads types and relatively cheap, annoying sometimes as some sizes / lengths have a minimum order Quantity, but they do usually turn up next day so its handy.

Thanks
