First post, "Hello"...

I've seen a lot of different designs and am curious about the 8020 setups that I've been seeing. I downloaded a pic of a table that looked interesting and wanted to ask some questions about it to the forum, hopefully the owner can chime in. (sorry for not remembering the link)

It appears that there are already custom parts that are made to order for building a CNC out of 8020, does anyone have a link to that site(s)?

What kind of performance/accuracy are you getting from the build?

In the pic I attached it appears the builder is using ACME rod but what type of linear bearings? all that I see are UMHW type do they make anything different? are they really that good as opposed to a roller type?

The steppers are mounted on brackets I assume these are manufactured as well?

Why the need for the multiple 8020's banded together - does it flex too much? does it really not make a good CNC setup?

I'm reading as much as possible but there is so much to learn for a neewbie.. hopefully you guys can help me out.

AJM,
