Hi guys,

I am trying to use Sequence Pro Generator with a Shoestring FCUSB adaptor and JMI motorised focuser.

The primary issue was that SGP would only work with absolute focusers. Now that I have ticked Absolute Focuser in the driver I have downloaded from Shoestring, I am struggling to get the focuser to work.

I am only able to get the focuser to move in one direction, unless I get it to go to a certain position by setting the absolute go to value. The default value that comes up is 50003

With absolute focusers, can someone advise me as to how I set the focus point or how I can zero the focuser as such? SGP does have a zero focuser set position, but essentially the software seem to simply extend the focuser out and then keeps going unless I get it to stop rather than recognise that it has reached the end of the focus tube.

If anyone else has used a similar set up and can advise the setting I should be using and process with Sequence Pro Generator to start doing V curves that would be great!

Thanks in advance,

John K.
