Modbus / New to cnc and software controls, need some help
« on: September 18, 2012, 07:40:05 PM »
Hello to everyone and thanks for all the work you've done
Im totally new to cnc and the hardware and software but I have managed to get enough together to build my first rough draft machine and get modbus working with a arduino and mach 3 but have yet to connect my controllers up to the arduino due to having no clue what pins to use with Shillings modbus sketch I found posted on here.
can anyone help out with which pins I use for these connections?
