Thanks for the pictures.

Does your machine have a blown controller? I wouldn't throw too much money
at a turn key PC upgrade. It is simply not that different. Especially with
your skills and knowledge. Either BDI-EMC (Free, Linux, Can be a little
choosy about install, especially graphics cards) or Mach2 ($200 -WIN
NT/2000/XP - supposedly the same motion core, limitied to 45Khz), or
TurboCNC ($20 - Dos - Up to 100Khz+, doesn't support constant velocity
conturing or tool radius compensation).

Is your mill a servo or stepper system. If the drivers blow on a stepper
system, buy Gecko G210's. For Servos, Gecko G320's, but you need quadrature
encoders where some older hardware is fitted with Tacho's.

I am mainly gathering motion controller info for future use.
It is servo system with pulse encoders I think. I am not sure about
the encoders as I am still gathering info on the Kasuga. The servo amps
have been replaced with new Servo Dynamics units. The Speecon spindle motor
amp/controller is also new. The main problem with the Bandit controller is it is
limited to 1000 steps. I'll know more after I make a few three D parts using
DMC.

Paul,

It sounds like you and I may have the exact same type of CNC mill. 
I just bought a Kasuga V2 mill with a Bandit I controller and
Quickdraw toolchanger. I am in the process of designing a new 
controller for it. My controller will be very similar to the one
ms-tech offers. I have requested a quote from ms-tech for a package 
to retrofit the Kasuga. I am just curious about the price. I
expect it will be far more than I would be willing to pay for 
a retrofit. My Bandit has a problem in the X axis. I am in the process
of repairing it just so I have something to play with while 
I work on my own controller. Did your mill come with any schematics for
the Bandit? I got a manual, but it is missing some of the 
schematics for my particular configuration of the Bandit.

BTW, if your mill is like mine, it has resolvers AND tachometers 
for the position sensing. The Bandit reads the resolvers. The tachs
are just used for feedback to the amplifiers (they get a velocity 
command as opposed to a power command).

No schematics. I am trying to find some.

I too sent them a request for quote. I am going over there next week
to get a demo.

Do you have a wiring diagram on the Speecon 3 phase 3 HP spindle motor controller?

ms-tech has some resolver to digital converters I think.

Where are you Harrison?

BTW I just bought two connector used for the RS232 link from Digikey
