Re: Mach1 Unable to Find Home Position Suddenly

Ray Gralak

Hi Mikko,

I'm glad the problem is solved but I don't think that re-installing the driver had anything to do with that. The driver has fixed Hour angle/Declination positions for the park positions which would not have changed by reinstalling the driver.

BTW, when you say "Home Position", did you mean "Park Position"? With APCC you can define a home position but the AP V2 ASCOM driver doesn't have a "find home" feature.

Just an update. I "played" with the mount today and more I slew it, the further it missed the home position. Then I
uninstalled and reinstalled the driver and the problem disappeared. I slew it half a dozen times and every time it
returned home correctly. Go figure...
