Hi
I have a Dugong drive and a Keling KL34-180-90 servo with a US digital 250 line encoder. I've tuned a few servo systems before but I can't seem to get it tuned at all. Not even on the bench! I can't seem to get any kind of smooth motion out of it. By the time I get enough AP so that there is power and enough AD to stop oscillations the moment is really jerky. I spent 4 hours yesterday trying different tunes and changing out encoders trying to get this figured.
The Dugong drives are currently running my router and I was just going to upgrade the X axis so it had more oomph so it's not a defective drive. I also have 2 of the servos and they both perform the same.
Does anyone have some starting tune numbers they can share?
Thanks
Derek
