General Mach Discussion / Re: Using Mach 3 Pulsing Engine

Thank each of you for your ideas.

There's another method, and that's to make a rectangular pocket, and along with stirling's suggestion to set the pulse rate.

Along the way, I also wrote an application to mess with the port bits, using C++ Builder.

...but the Servo Frequency Generator is the best.

There is an option in Mach3 to do that. It does a back and forth motion to be able to tuned a servo.

(;-) TP

Where would I find the option in Mach3 to do the back and forth motion?

I suppose the question is why and for what purpose do you want to use it ?

Tweakie.

I would like to use it if it's possible, to make a pin pulser at some rate, for the purpose of setting my Geckodrive 320 gain and damping pots, while using an oscilloscope.

The instructions (Mariss wrote them, I believe) show to set a pulse count of around 40 steps/second, and also control the direction pin at the same time, while adjusting the pots, to obtain a properly damped control.

If the pulsing engine is capable of doing that, and the software interface is known, then I can write the program to enable the pulse for each of my 3 axis step and direction pins.

Alternatively, if some of you could point me to a similar tool that allows pulse rate on a particular pin, while controlling another pin high/low, that would suffice.
