Newbie- UHU servo controller questions

[cnc2]

Hi every body on the forum !

I'm about to build a 3 or 4 axis milling machine & i want to drive it with servos using the UHU controller board & my questions are:

1) What is the latest version of UHU board & where to get the files to make it by my self ?

2) Which step/dir parallel interface are you using ? is this one suitable for UHUs http://pminmo.com/4axisopto/4axisDIYopto.htm i'm not sure 'cause the board function is stated "4 Axis fast OptoIso interface" & it's current limiting is stated "DB25 to IDC with High Speed Opto Isolators" & there is no user's manual, does it include all what is needed for a milling machine (limit switches,spindle ...etc) ?

3) What do you think about the Ametek 38vdc servos from surpluscenter ?(if you are using them please let me know about the performance they are reaching & their rear shaft diameter) or if you know a better performance to price ratio let me know ?

4) What encoders are the best & cheapest (or salvaged) for UHU & what is limiting the resolution to 1000 line on uhu ?

Thanks !
