I am having some slew freezes going on with my AP900 mount, SGP and APCC.
Seems to happen more so during either the meridian flip or when recommencing from a recovery due to cloud etc.
The scope will start to slew, the large “Emergency Stop” square comes up, bu then the mount will stop and SGP will simply hang in “Slewing to target” mode.
If I then press the emergency stop button and then get it to restart this seems to go back to slewing but only sometimes.
Really odd!
Have the latest version of SGP and the AP V2 driver installed.
Just wondering if any other AP users have experienced this.?
That version is not even close to the latest version. You should update to the latest version because I believe there is a fix for the issue you are reporting. The latest version is 1.8.3.1.
With the latest versions installed, I have now run into a new problem. Mid way through a sequence SGP tried to unsuccessfully do a meridian flip and pretty much stops the scope. The scope scope does not go into recovery mode.
When I get things going again, and it’s time to do a meridian flip, it fails to do this. I have to ask SGP to centre to the object and then it does it.
If you can please have a look at this. It may be something on APCC and the way it’s talking to SGP - I did ask APCC to do a positive meridian delay to flip earlier.
APCC doesn’t know anything about a “recovery mode”. That sounds like an SGPro feature. If the scope failed to go into that mode then maybe you have something misconfigured in SGPro.
There have been changes to the functionality of the Meridian Limits since the version you were using. You should review APCC’s help and make sure you have configured the Meridian limits options correctly in APCC.
BTW, I can’t access your link. It says I have no access.
I found a reference to a failed meridan flip but it looks like something SGPro decided, not the ASCOM driver or APCC:

Just one more thing - I did not have Enable Meridian Tracking Limits checked in APCC. For tonight’s session I have checked this - screen shot attached - does that look right to you?
No, that’s not the way you should configure APCC. You do not want APCC to automatically flip the scope, which is what you have configured.
You might as well uncheck "Enable Meridian Tracking limits as you don’t have any defined. The mount will then flip the first time SGPro issues a slew after the meridian has been reached.
