hi phil,
my motor/spindle is from zentoolworks.com, sorry i dont know how to provide a link
i realise that mach3 has 2 ways of spindle control, seeing as my driver board has a spindle relay just wanted to know how it can be used and what other hardware i would need, i.e motor control board. dc varible speed controller
i was hoping there would be one board i could connect to my driver board spindle relay and my spindle
