Hi,
From what you describe it sounds like you need to make the setup accoring to the Tatanis setup document:

(The endpoints need to be set up to go from 0 to +100 instead of -100 to +100)
You can also find some general information in the manual:

There are also many videos on Youtube that shows how the calibration procedure should look. For example:

Also, there was an automaitc Windows 10 update that broke the USB input on some machines. Don't know if it applies to you but I thought I might mention it just in case.SB drivers. You can find more information here:

If you can describe more clearly what the dots are doing during calibration (and later on the trim settings screen) I might be able to help.
