I have all the pendant functions working now except I have no idea how to get velocity mode.

However, I have another question besides that one that I have not figured out and it is time to quit on this for tonight.

If I do get velocity mode working or add a step that moves more than the now max .001, like say .01, it could que up a bit of moving if you spin the wheel fast. This means it could still be moving even after you stopped spinning the wheel.

What I want to know is how I can make it stop moving if the enable button is let go, but it still has not finished moving the commanded distance? It seems like it would be safer if something bad happened and you let go of the switch but it was still trying to make the queued up moves.

However, I have not thought of anything that releasing the button would not cause other moves not to work also because the state of the switch will be off normally when the pendant is not being used. So, telling it to stop anything moving when the button is released also might keep anything from ever moving. If that makes sense.

So, any ideas? Here is my code on the pendant so far. Some stuff is commented out because I ended up not needing it for now. I will clean it up when I am done. I don't know what shuttle mode is and I cannot find what it is so far. I was hoping it was another name for velocity mode, but it does not seem to do anything. I read one post about it in mach3 forums and it said something about moving through g code faster or slower...would be nice to know what it is.

I don't know what mc.mcMpgSetEnable is either, so I was trying to see if that disabled and enabled the MPG. It does not seem to, but I cannot find anything about that. You will see those commented out also and put back to setting the axis to -1.
