Hello - I've been pulling my hair out trying to get Mach3 control of my Chinese 2.2kw spindle with modbus through a Hitachi WJ200. Unlike many of the threads I've read on the subject, I've gotten past the point where my rs485 converter is talking to the Hitachi. I can open the serial port and read registers from the WJ200, I just can't get Mach3 to control the spindle. I believe I've got some dumb error on the Mach setup screens or the brain config. Attached are screenshots of all the applicable (I think) settings. If you see anything obviously wrong, please let me know.
Thanks,
Kent
