It might be overkill for your application but might give you some

We just got an acroloc which has a general numerics control. It is
using siemens drives.

The servo drive uses what looks like 3 of similar circuit boards.

wondering if anyone has any info on these drives..
servos..
I meant - the spindle drive looks like it uses 3 similar cards. (hooked
togather with ribbon cable..) It is the 3 cards in the center of the rack.

I think the table rotation is between the x and y axis...
So - a square against the tee slots and then use the y axis?
I could see some sort of fixture that sits on the table/aligned with the
tee slots and has 4 bored holes that you probe and then do the math?

I think mach has a place to tell what the 'radius' is of the rotary axis
so the feed rate is calculated based on that. (but they cannot do kins
and such) Inverse time really is the only way to go - that is what the
big boys use.
