Oops, I got the impression that you didn't use pull studs. I just sold some NMTB40 holders on eBay for less than $20 including shipping. Your CAT40 is much more common. I would think that if you shop around on eBay or Craig's List, you could get the same or better deals. > the amps look identical at a glance, im on lunch break so im tryin to > keep it quick. the motors are all directly connected to the amps, > thats why i thought to send the quadrature to both emc and the amp. In most cases like this, you would run wires from the encoders to both the amp(driver) and EMC. The problem is in how EMC would use the information. It could be used for the position display and if needed for motor control feedback. Knowing how your drivers work will determine that. What I would be looking into next would be to trace the connections that go from your driver to your controller to see how many wires there are and see if they are labeled in a useful way. > there are aluminum strips along the ways, i havnt seen any connectors > on them where they would be scales, but it's a possibility.

This doesn't seem to be a project for a beginner. I wonder if you would be better off selling the machine and getting something like a Shizuoka ST-N which can be had for around $1800 and would be an easy conversion. Of course the parts you are making would have to fit the workspace. Shipping is a big problem too. You will get the best price for you machine if you have a shipper and lift prearranged and you can wait for the best offer. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
