MACH3 SPINDLE CONTROL - CONTROL BOARD HELP

Hi All,

I wanted to post this issue that I am having with setting up Mach3 to control spindle speed, I have watched and read a lot of instructional information on Youtube and Google search but still with no luck.

A brief over view of what i have done is tick a few boxes and put a couple of numbers in the spindle motor outputs and spindle setup - but was not confident in what I was doing and didnt want to choose the wrong pin port number and cause and issue's

I noticed with one setup that there was a slight humming sound coming from the machine when the RPM SPINDLE CW F5 was turned on and the SRO% was moved upwards - so I pretty much stopped trying to do it and to look further into this.

I thought best place is here as I have seen and read some pretty amazing and knowledgeable things.

See below images with Pins And Ports for the Control Board and Mach3 etc
