That really doesn't matter. I am using an arduino to control it. Currently I use the serial port to select the tool number (1 though 8 ). If I could use a serial port that would be great, cause then I would be done. How the system works is:
1. Tool changer receives tool number
2. the locking pin is retracted
3. the turret turns to position
4. the locking pin is engaged
I can use any sort of input from Mach 3. Serial, I can clock the number in, I can accept the address of the tool (using 3 lines). The output from Mach 3 really doesn't matter.
I understand it's written in VB. What I need to know is where do I put the file when done, what setup does the file need, What is the list of command that mach3 will accept that are no part of the basic VB library, can it use the standard VB library. I'm just not sure where to look for it.
