Hello, I am hoping someone can help me with Modbus and the K6100A router .

I am running a Fuling DZB300 Inverter with a 3KW spindle.

I have recently converted the machine to run with Mach 3 and I would like to control the spindle via Modbus.

Everything is running correctly with Mach 3 - which has taken some time, but it has been interesting and it is a great education to the ins and outs of controlling CNC equipment.

The parallel port breakout board is a CNC4PC C11 board.

My next step is controlling the spindle with Modbus.

Do I need to purchase a Peter Homann MODIO board and a serial card for my PC.

If so is there info anywhere that can help me with the Mach 3 setup of the Modbus setup to control the inverter.

I have searched all the forums etc, but can't seem to get the exact info I am after.

Thankyou for any assistance.
