my 6040 has been gathering dust a while as i had no pc with a parelell port. Eventually i got one of those unc300eth gizmos which was easy enouth to hook in. i reconfigured mach3 to talk to it but for some reason i can not get the spindle to fire up unless i do a major config changes then it fires up until i hot the reset button. the pin goes high when i press the spindle button. I hear a relay clicking and the rpm on the software spins up only to spin back down again. the spindle never moves, unlessi do a major config change. plug it from port 2 to three etc
not sure what's going on. all the steppers work fine.

Wny ideas please?
