I got it working and was able to move this at signals actually see what's happening.

I don't see that crazy movements describe seeing in Hal Scope., but what I do see applies sharper the line that off the screen that fat then a second later actress back in the screen in a large arc goes back to normal.

LMAO I think I was half asleep when I wrote this.

Sorry for that garbled mess..

So what I was trying to say is I was able to get everything situated in Hal Scope and see the signals but when comanding the short jogs as you described I was not seeing the signals jump all over out of control. Instead what I would see is the signal would spike up vertically in a straight line off the screen the about a second later it would drift back in the screen and in line with the other line in a giant sweeping arc.

I did play some "I" and that did make a change and eliminate the giant spike, but then the signal never came back in line and seemed to just chase itself producing a endless sine wave.

A couple of suggestions:
1. Don't use any I or D only P and FF1
2. Make sure you remove all the PID maxerror lines in the hal file

PCW,

I will check into the maxerror lines.

I should have mentioned that I started with P and some ff1 but I wasn't getting any visible change as I think the error was so large. I got nervous to be making large changes. Is there a safe range to work in or is it all just case by case.

If you dont have the maxerror lines removed, you will no be able to tune

You can either calculate FF1 (10/velocity@10V) or scale the analog output
in velocity in which case FF1 = 1.0

An initial P value of 1 is probably OK
