Morning,
Sorry if this is the wrong location to post this, but seems like the closest.
I am building a 5.5ft wide by 15 foot vacuum table plotter / fabric cutter. I will be using 2 Nema34 motors for moving the Gantry and 1 Nema34 to more the tool head carriage. Will have 2 airheads that are on air cylinders to activate through a relay switch. The primary tool will also have a Nema23 to rotate the hot knife when cutting curves.

What I need help with is recommendations on Controller Board; can use DB25 or USB, controller 4 stepper motors, and able to send outputs to seperate relay switches. I also am not sure what software to use that will allow me to control the hot knifes rotation on curves.

I have heard of the Mach3 being able to do this software wise, but open to any ideas.

Thank you for any help,
Shane
