Hi Manu,
I've had a look and I'm fairly sure that I can get the DigiSpeed-XL produce an RC signal that should work fine. I can add it as a mode selected by the mode jumpers.
I have a question. Normally a pulse of 1.5ms centres the RC servo. 2mS is full CW. 1mS is full CCW.
Do the RC motor controllers use 1mS as off and 2ms full throttle, or 1.5mS is off, 2mS is full throttle, and 1mS is full reverse.
I think some of these will be a problem unless you can write a macro to cycle the RC pwm to reset the speed controller out of failsafe.
They tend to have a safety failsafe which requires the sticks to be moved to various positions until bleeps are heard, only then is the device armed.
Some of these motors and controllers can produce wicked power! A friend of mine competes at world level in f5b, and those brushless aveox motors etc with 30 cells produce several horsepower.
I may speak to a friend who designs his own brushed and brushless controllers. He may be able to come up with something more suitable to the cnc cause.
