Software PWM, and proportional cuts

Hi Jerome,
My board doesn't have wire heat control built in (early Hobby CNC), and the usual PIC solution seems a little excessive when we already output square waves from the software to the board. My board didn't have timer either, but that is a simple 555 timer circuit.
Would it be possible to have Jedicut output a PWM signal instead of the existing heat signal (I'm not sure what it is at the moment)? That way, all we need to do is connect an inexpensive power transistor between the supply and bow, and feed the PWM from Jedicut to the transistor input. No need for heat aquisition as it is set from inside the software already.
I have manual heat control at the moment, but it would be much better for to use your dynamic programming I think.
I am just starting to use Jedicut, but so far I like it a lot!
Regards,
Simeon.
