Hi,

I have an old Bridgeport mill that was retrofitted back in the late 80's.  It is using a DOS based controller and I would like to get it running on Mach3.  It is using
 MAE HY-200-3450-700 B8 steppers.  would the 340 be able to run these steppers?

Steve Stallings:
Sorry, but you are going to need a significantly more powerful driver to run that machine.

The PMDX-340 is rated to run motors that require up to 3 amperes. Your motors require
7 amperes.

If the power supply and motor drivers used in your old controller are salvageable, you
may be able to upgrade just the logic portion. This would require a breakout board or
smart interface that could work with Mach3 or Mach4.

apayne:
The controller still works but it is not compatible with new computers.  can you recommend the break out board or smart interface that I could buy form you?

thanks,
Aaron

Steve Stallings:
My most likely recommendation would be a PMDX-424 and Mach4.... BUT....
it would be best to know more about your existing controller before you
buy something. Can you provide information about the drivers and power
system, or some photos that would allow them to be identified?

apayne:
It is a Centriod CNC controller
Model  CNC-B24-MD3
Serial # 1032

here are some pics and it looks to be 1989 vintage.  hope this helps to make sense of it.

Aaron
