John,

The Unknown Error is now gone. I'm running v319 of Robert's firmware which is the latest.

Sorry, yes I mean Quadratic! I switched to Parabola and it seems to work fine every time. I did try Hyperbolic for a couple of cycles and it also seems to be working well for me. When on Quadratic sometimes it chooses the final sample position as the solution even though the value calculated on the chart is very different. As you see in the screen shot above. I really don't think this would be anything to do with backlash settings.

The next time I power it up I can send a screenshot but I can confirm that both in and out are disabled and all values are zero. The image in the manual is using the Windows test application. These can also be set in the INDI driver which is also set to disabled.

Thanks
Ken
