The position of the mount on KStars does not move from the celestial north pole

The position of the mount on KStars does not move from the celestial north pole was created by tkakura

I am having an issue where the position of the mount on KStars does not move from the celestial north pole when I let it slew in EQmod.
I am assuming that perhaps there is some error in my settings, but I have no idea what it is and am stumped.
Can anyone give me some advice?

Environment
INDI, INDI 3rd party drivers: Version 2.0.1 on StellarMate OS 64bit
Mount: Star Adventurer Gti
KStars 3.6.4 on Windows 11

Reproduction procedure
1. Start KStars.
2. Create EQmod and CCD Simulator Profiles and connect them.
3. In KStars, mount is on the north pole of the sky.
4. Unpark the mount.
5. Right click the mouse on Polaris and execute Goto from the menu.
6.Star Adventurer GTi moves in the direction that seems to be Polaris, then performs Iterative Goto 5 times and turns in the wrong direction.
7. On the other hand, the position of the mount on KStars does not move from the celestial north pole.

When the same thing is done with Telescope Simulator instead of EQmod, the mount on KStars moves to Polaris and the Interative Goto is not executed.
The time on Raspi, the observation time on KStars, and the observation location are set correctly.

disabled debug log, it is part of attached file log_20-50-49.txt.
Target star is Polaris.

Attached is a video that reproduces this issue.

This issue is reproduced in Star Adventurer GTi
It is not reproduced with AZ-GTi and the mount position on KStars has been correctly moved to Polaris.

It appears that the Star Adventurer GTi is faulty.
The SynScan Pro app also does not work properly in the DEC direction, and the indicator does not reflect the angle of the DEC.

Hi tkakura,
I 've had similar Problems with my StarAdventurer on KStars.
In my case the problem could be resolved by this process (copied from Stellarmate FAQ):
- If the mount is not already unparked, unpark it (click the green flag in the toolbar).
- Go to Ekos Mount tab, and click on Purge all configuration. This will clear all settings related to the mount. ekos purge mount config
- Disconnect and Stop Ekos.
- Power off the mount.
- For equatorial mounts, if the mount is not pointed at the celestial pole with the weights down, adjust it manually until you reach this position. For Alt-Azimuth mounts, make sure the mount is in its home position.
- Power on the mount.
- Start the Ekos equipment profile again.

Now, depending on the mount type, it should have the correct startup position:

EQMod: Mount should point toward the celestial pole and a new default parking position is recorded
Other: Mount should point toward the last alignment star that you used in the handset when performing the initial 2 or 3 star alignment process.

Hope that helps
Stefan

My SA-GTi had a defective DEC motor. It was repaired today and will be picked up tomorrow.

My SA-GTi malfunction was successfully repaired and it now GOTOs correctly.
