Re: following error problem, Thanks.

Thanks Tim,

I follow that.

I've never seen so many system parameters have such an effect on each other.

But I'm beginning to get a feel for it now. Between you, Ray, and John (freqmod tuning) I'm beginning to get a better understamnding of it. It's just confusing to the beginner trying to understand how all these functions work together at once.

Not like DeskNC where you have just 3 settings to worry about. I remember when I was staring at it one day on another system and the lights just suddenly came on. I understood it all. You helped me with that on too.

Maybe one of these days I'll have that experience with tuning EMC.

Thanks again,

Don

As you increase the steps per inch you have to also up the P values.

Subject: following error problem

Hello to all,

I have an earlier version of EMC now somewhat operational with a small stepper setup for experimentation purposes.

Tim and Ray have been very helpful in getting me this far.

I am running linux 2.0.36, june 2000 EMC release, rtlinux_09J. I am using freqmod.

I can run with out errors if I set INPUT_SCALE and OUTPUT_SCALE to a value of 1000. If I set thes values to 4000 to reflect 4000 pulses(steps) per inch for a 1/2-10 acme lead screw I get following errors.

Can someone give me an idea of what other variables I may need to change to get this to work?

Thanks,

Donald Brock
