Leo,
Yes my board will interface with the BOSS 3. You can PM me your email address and I will send you some more information, or you can email me at
ashburn@icx.net.
The BOSS 3-5 actually rapids at 60 IPM, 1000 pulses per inch or 0.001" resolution. The BOSS 6 rapids at 30 IPM with 2000 pulses per inch or 0.0005" resolution. The difference being 1:1 motor to ballscrew ratio on the BOSS 3-5 and 2:1 ratio on the BOSS 6.
I just aquired a Mazak V5 with a Fanuc 5 controller for $750. Here's the hitch, the mother board is bad. A reconditioned board is $9000 and a new one is $13,000. Needless to say it will get retrofitted with Mach 3. Besides I prefer a CRT to the LED digit gas pump display, similar to the BOSS 3-5.
