I am looking to upgrade my 2006 Vexta stepper motors (DC 2.65V, 2.1A) w/ servo motors. I am running a 5x8 table w/ 4kw E25 HSD spindle. I cut mostly wood for cabinets and high end furniture.

What is the correct Teknix sevo motor to get (4 needed). What do I need to take into consideration when doing change-out to avoid pitfalls.

My goal is to bring my 2006 shopbot up-to-date so that I can get faster production and higher precision.
