I just purchased, received and have setup my first ShopBot Desktop Max with a 6" Rotary Indexer. I have installed everything and read all the documentation but am not sure how to physically zero the A & B axis properly. I have learned that the "B" axis is the rotational axis around the X axis and the A axis is the rotational axis around the Y, (is that correct?). I've read through a multitude of posts but haven't came across one that instructs me on proper zeroing. Does anyone have a link to proper instructions or perhaps can you post this procedure so a newbie to indexing can accomplish this? Thanks for any info and/or assistance in advance.
