I am wondering if there is a good software for driving a stepper motor by an equation of variables provided by other motor positions.
I want to make a bevel head for a plasma cutter that will have a fixed angle of bevel but allow the head to "caster" (the 4th axis) to follow the tangency of the curve created by the x and y steeper motors.
I think this can be done by counting the steps of other motors and creating logic using another programmable controller but i am looking for a software first. I have Mach software which does do equations but its basically to scale what you are inputting.
Research "tangential knife control" Mach is supposed to do it, I'm not sure how well it works.
