Re: Hit RA Safety limit and couldn't move away from it.

The servo imposed limit is written so you should always be able to back out of the limit.

??? //

??? // If the position counter is outside the valid range only allow steps

??? // that will move out of the forbidden zone.

??? //

??? bool direction = GetDirection();

??? if (!checkLimits ||

??????? ((posCount < lowerLimit && direction) ||

???????? (posCount > upperLimit && !direction)) ||

??????? ((posCount >= lowerLimit) && (posCount <= upperLimit))

?????? )

??? {??

I was using the touch screen diamonds, but I seem to remember that I also tried the physical buttons.

I was resetting the worm mesh on my G11 (I¡®d been getting RA stalls) and during testing I hit the RA safety limit.?? My problem is that I couldn¡¯t use the arrow keys on the HC to move the mount after that.? Surely I should be able to move out of the limit?

What am I missing?

Hi David,


I've not had that happen to me. Were you trying to use the touch-screen or the physical buttons? Did you try the ASCOM driver virtual HC buttons? Does it happen every time you hit a safety limit or occasionally?

?

The one thing that could explain it is if the mount somehow reached your hard servo firmware-imposed limit to stop the mount from rotating a full 360 degrees.
