For my AVX with the QHY5/SSAG autoguider I cannot get autoguiding with pulse guiding working.  This is for Kstars 3.5.2. 

What I see is as follows:  RA forward n steps, RA reverse follows with n steps in the same direction as RA forward, then keeps going in the same direction with steps twice as large.  It continues until it fails. 

I tried this on numerous nights (thinking I was doing something wrong) with various step sizes and both smart and multistar autoguiding so it is very reproducible. Fortunately after I connected the ST4 cable and selected guiding via the QHY5, everything works fine.
