waiting in the mail for this to arrive
was hoping to get this working with linuxcnc with a simple modbus usb adapter
preliminary research might be one of these.
New CNC MACH3 6 Axis LPT Port MPG USB Card Motion Controller Adapter 200KHz
Item price C $57.69
was recognised by mach3 in virtualbox on windows 7 after putting the nc200 driver in the plugins folder.
was not usable / recognized on linux.
