Does the card comes with a CD that includes MACH3 plugin + user manual?
If not,
Ask the seller for it.
Some card are NOT compatible with MACH3 but made for UDBCNC,
TB6560 is just the name of the Toshiba Driver IC used in many CNC driver boards. I have the parallel port version which can be eaisily used with MACH3
The USB version needs a MACH3 plugin or it will not work.
