Hi Chris, thanks for the reply. I think you are already ahead of me one step.. I am confused as to where you see stepgen.2.maxaccel ties to the .ini? The only stepgen.2 I see is the the loop written into thc300.hal for the commanded position and feedback loop. Can you share where you are seeing the maxaccel tied in? What you say makes a lot of sense to me, i just haven't been able to find that part yet!! I have read the entire HAL integrators manual cover to cover, and most of the rest of this config makes sense, but it's very complex and hard to follow!
So to answer your question, I guess the lightbulb just turned back on in my head that you have to reference in your hal config anything you want to follow back in the .ini for the limits to take place. Since I haven't been able to find that reference, I assumed (incorrectly) that an axis would never exceed the .ini setting as a hard and fast rule.
