Yes, it is functional, BUT, the cncsaw screen is a stand alone control, meaning when you start up mach you goto view and load the CNCsaw screen, it is your CNC controller.
Mach has to be loaded for it to function cause it will load the Gcode into the run window.
I have Enclosed a "Zipped" copy of UPDATED CNC saw and "CNCsaw Brain" in this post, please download the screen set, and place it into the Mach3 main directory, and put the brian in the brian folder.
Also I added a "Brian" to it that will monitor your inputs for Clamp not closed which turns on an LED and puts the system into feed hold, since it would be unsafe to operate without the piece clamped and not work as well. You will need to Set up OEMTRIGGER1 to the ports and pins you want to use for the "Is not clamped" prox swtich.
OEMTRIGGER2 is set in the brian to to monitor for Blade Brakage, it turns on an LED, and Estops the system. You will need to set it up port and pin as well.
OUTPUT2 is the activate (close) your roller clamp, you will need to pick port an pin.
M8 is your flood coolent, you can tick off output1 for your flood, and set up outputs1 port and pin.
