have any of you had and issue with overriding the spindle speed once you have it set at a certain speed? When I try to override the spindle speed the motor instantly revs up to the max around the 3000 rpm range. any ideas?

thanks
 
Chad,

You need to do an M5 before changing any S parameters followed by an M3. Also, Mach 3 is loaded with quirks when it comes to that spindle speed interface. I don't even try to Mach 3 to control the spindle and just give it M and S commands through the CLI.
