Re: APCC 1.8.3.1: strange behaviour when parking at Park1 position


Yves Laroche
 

Hi Ray,

This morning, the mount behaved the same as other night.

APCC was the only software connected, no ASCOM driver.  I parked the mount to Park1 position and the mount slewed at the opposite direction.  I decided to let the slew completed.  The mount parked at Park5 position.  I unparked the mount from that position (Last Parked Position) and park the mount to Park1.  The mount slewed back to Park1 as it should.

There is a logic software problem in this version.  Never see hat kind of behaviour before.

I'm using CP4 controller.

Regards,
Yves

Yves,

I'm saying  if the mount was slewing someplace other than Park 1 then there's not much that could cause that besides a communication error. Park 1 is always the same coordinates (hour angle and dec) so APCC is out of the picture once the commands have been sent unless, like I said, there was a multipart slew bringing the mount out of a cw up position (and only relevant if you have a GTOCP3 since the CP4/5 does that by itself).
