I have a need for a refresher course on the proper usage of the new

the accuracy of my machines that use it has gone to the dogs, hunting

rip them out and put stepper/servos on this go704 at around $250/axis.
I would suggest that the first thing to do would be to step back to 2.8 and
see if the issues you see disappear.
Unless you actively engage auto-tune mode the component should behave the
same as it always did.
Have you changed the PID settings at all since your machine was working
properly?
yes, considerably. The previous settings were more like WAG's that
worked. But see my other later post, I wasn't following ALL the
instructions. My bad IOW.
Take care & stay well Andy.
Cheers, Gene Heskett.
