I am running EMC2 on a D&M 4 cnc vertical mill. I have bypassed the onboard control card and I am connecting step and direction directly from my computer parallel port to the drive cards for each axis. I am presently turning the spindle on and off manually. Everything seems to work great but I don't have CNC control of the spindle.
Question??? Could anyone share with me the schematic or the block diagram of the main control card so that I can figure out how to connect spindle commands to the machine from my computer??? If anyone has the docs for this machine I will gladly pay for the expense of copying or scanning. I have reverse engineered the individual axis driver cards and will share the schematics of those with anyone who needs them.
Thanks,
Cecil
