Hi all,
I currently have emc2 running through the parallell port connecting to a hobbyCNC pro board.
I would like to have more pins available for hardware buttons, therefore I am considering a Mesa 5i20. is there anything I should be aware of when going down this road? how are you guys interfacing your driver board? any easy Mesa-to-parallell(HobbyCNC) cable available? Do I also need an opto coupled BOB for the buttons etc?
Thanks!
Henrik.
