I recently switched from an ASCOM/SGP-System to INDI/EKOS on a Stellar-Mate - everything is up to date...
While I'm now able to do my basic astrophotography tasks incl. guiding, etc. the park/unpark sequence results in continuous rotation in both axis until the cables get tangled and a mechanical error occurs.
Allthough I'm aware that there are no hardware decoders in the EQ6-R the parking was no problem under ASCOM.
I synced the mount twice to get its coordinates right (once roughly at polaris and afterwards on M31), but the parking-command just led to the behavior mentioned above.
Does this sound familiar to you and does someone know a remedy?
I have an EQ6-R as well and have no parking problems whatsoever. When you start INDI you get a popup with the properties for all drivers that were started. Open the EQMod tab and go to site management. There, click default and then make sure to save the options. That should fix this for you.
As Wouter said, start with the mount in home parking position, then go to Site Management tab, then for parking position click "Default" then Write. It should save this position as the parking position. Now park, it should park in this position. Try unparking, then slewing to some position, then parking again and see if it returns to the same parking position.
You don't really need clear skies to test this. Start INDI, make sure that the telescope is in the correct park position and click default and then save, as Jasem suggested. Then just pretend to slew to a star or use the mount controls (from the mount tab in Ekos) to move the telescope. Then park the mount and it should go to the park position that you just saved.
After following your instructions parking works as expected.
The important point is, that the button to save the configuration is titled "write data" and is located directly next to the "default"-button - at first I was confused with the Save-option in the config-tab...
So now it's time to sort out the other things as unexpected tracking-speed-increase...
