I have tried all the settings from 256 to 2048 but it just makes it worse if I set it up (from 256). The tuning info on the Gecko page (http://www.geckodrive.com/ark-4/support.html?pid=33&id=112) says to use 1/2 the encoder line count. We are using CUI AMT-102 encoders which are set to 2048ppr. So I tried 1024 but I am not sure it makes much difference. > > The encoder resolution will affect the error gain.

I have played with this a bit, and didn't think it helped, but will try it again and try tuning on a lower gain setting. It is currently set for default (medium gain). > > The description in the "Current Limit" section of > the manual incorrectly references switch 10 where > it should reference switch 7.
