Mach3 spindle control of Boxford 260 VMC - CNCzone.com-The Largest Machinist Community on the net!

Hi Guys,

I've successully replaced much of the guts of my Boxford 260 VMC with a PC motherboard and 3 new stepper controllers from Motion Products and am now left with how to control the spindle. I'm hoping I can use the original spindle controller but that's as far as I've got.

This is the original Boxford controller:

Anybody recognise it or have any idea how I might go about interfacing with Mach3?

Cheers
Chris

the thin black wire is the analogue input. about 8v dc (normally 10v)
using the step pulse only and a d to a converter the spindle speed can be controlled
the green/yellow wires are ground

hope this helps
