What switches in the configuration of mach3 control the on and off of the router?  My router runs exactly opposite so that before I start a routine I have to go in each time and change the gcode.  Otherwise, the router shuts off when it is supposed to start . ........any help would be appreciated...Thanks

Hi, Notselrach

It's probably the "Active Low" setting for your M3 CW Output pin setting, You should just need to change it's "State" I think.
