We purchased this machine a couple years ago. It is an early 80's model with a mx1 control. The servo and spindle drives work just fine so we are planning on re-using everything that we can.
Going with mesa (of course)
We lucked out an all the axis encoders are 5v differential (some had 12v)
The setup is going to be
Code:
computer -> Ethernet -> 7i80 -> 7i48
V
V -> 24 port opto22 board
V
V -> 7i44 -> 7i73
V
V -> 7i69 -> 2x 24 port opto22 boards
That will give me
-6 axis of analog out/differential encoders
-72 i/o
-panel interface MPG's and i/o
-expandable
Currently We just started and only have worked on getting a basic spindle encoder installed. It doesn't have one and we would like to be able to rigid tap.
We are using gear teeth sensors to do the quadature+index (they are not mounted yet)
This is a 69 tooth gear.
This will be slow going as I will only be able to work on it a few hours a week.
