Analogue interface card

Hello Forum,

Its been a while since I posted a question here. This si not because I know all the answers but rather because I didn know how to overcome the barriers to recovering the pass word ( original user name Zig present Zig5 should give You some clue as to what I know ).

Anyways.. I would like to connect galvanometric motor to linuxCNC. The movement is purelu analogue with analogue positional sensor .

Any advice if there are any interface cards which would provide analogue set point signal and accept analogue feedback voltage.

Presently I use mesa 5I20 and 7I33 to provide analogue set point and encoder inputs. So some kind of a solution along those general principles with fully analogue capability will be considered..
