Basically, I'm wondering what's required in order to have a PWM output that is adjusted on the fly based on how fast the tool is moving.
Something similar to this was done many years ago by Art and he used the axis step signal – the faster the axis travels the higher the step frequency and visa versa. This is fine for just one linear direction of movement but the math may become complicated for the blended moves associated with arcs etc. but something to think about perhaps.
