Jan and group another questions ?

There is a link, post or document where it is explained, symptoms in a cnc router table for backslash. Detection of backslash, correction of backslash.

Basically the question is How I know if my router table has backslash. How I know how much, what tool or procedure is used in order to measure backslash.


Thanks in advance
