[SOLVED] eqmod does not remember scope position.

Ok, that explains why encoder positions are lost when you restart the indiserver. Is'nt there a jumper on your board to disable this behavior ? If I understand it is used for firmware loading purpose. Otherwise you would have to park/unpark on every connection, not only when you power off your mount.

I'll come up with a script to do that, I have an idea. Will post the script once finished.
It would be nice to have an option called something like "read encoder position".

There is no switch for that, the firmware upgrade is one via a software.
If I can't come up with a suitable script, I will have to make sure that the mount is parked after each use and hope for the best that the Odroid doesn't reboot half through a session....

I've found the following post:
www.indilib.org/forum/general/522-parkda...or-indi-sx.html#2569




Is there a way to pass such values to the Eqmod on start, as in reading a file if possible, similar to ParkData.xml ? Or set it by command line with indi_setprop?
Or maybe, after each completed slew, the RA/DEC is written to a file which can be read on restart of the Eqmod, that would a cool feature to have.
You could choose to reload the previous location on restart if needed (in my case, after a power cut).


EDIT:
edited to avoid confusion, this is an example to show the lines "Setting default Init steps"

This is not my post, I took it as an example to show the following lines only:
[b]2014-12-31T16:19:10: Init() : Setting default Init steps -- RAInit=8388608 DEInit = 8388608
2014-12-31T16:19:10: Init() : Motors already initialized[/b]

I've been testing a few new firmwares for the AstroEQ but it still doesn't work.

Could someone guide me on how to re-inject the "default Init steps -- RAInit=8388608 DEInit = 8388608" back into Eqmod (Ekos) please?
8388608 is an example, I believe they are the default values.

You just have to create a ~/.indi/ParkData.xml file like this one:
<parkdata>
    <device name="EQMod Mount">
        <parkstatus>
true
        </parkstatus>
        <parkposition>
            <raencoder>
8388608
            </raencoder>
            <deencoder>
10644608
            </deencoder>
        </parkposition>
    </device>
</parkdata>
Use your saved encoder values in your case. Those values will be used on startup to set the encoder values.

Another solution would be to modify the /usr/share/indi/indi_eqmod_sk.xml file and set the CURRENTSTEPPERS property as read/write instead of read-only: that way you may directly modify it by hand.

I attach a small simple script to monitor the ra/de stepper values (add -h option to the indi_getprop command for remote host). There is also a -m option in indi_getprop to monitior values but I did not test yet.

Thank you so much, I will try it this evening.

In the worse case scenario, if that doesn't work or become too much of a pain the back side.... I might get myself a HEQ5 syntrek mount with a "HitecAstro EQDIR adapter for EQMOD" to replace my EQ3-2 / AstroEQ setup.

I have enabled this option in /usr/share/indi/indi_eqmod_sk.xml
<defNumberVector device="EQMod Mount" name="CURRENTSTEPPERS" label="Stepper Position" group="Motor Status" state="Idle" perm="[b]rw[/b]">
<defNumber name="RAStepsCurrent" label="RA Steps" format="%.0f" min="0.0" max="16777215.0" step="1.0">
1.0
</defNumber>
<defNumber name="DEStepsCurrent" label="DE Steps" format="%.0f" min="0.0" max="16777215.0" step="1.0">
1.0
</defNumber>
</defNumberVector>

Now you do have a new box in the Motor Status tab, you can enter the values there, but the RA/DEC Steps are not changing.

That above actually does work, the CURRENTSTEPPERS are set to the value from ~/.indi/ParkData.xml .
That gives me a work around which is a great step forward.
Off to write another bash script now.


Thanks for the help, I will let you know how I get on.

so far SO good, your script has helped me a LOT!!!!!

I have made the following modification to it:
#echo "$0: rastep=$rastep destep=$destep"
cat << EOF > /root/.indi/ParkData.xml
<parkdata>
    <device name="EQMod Mount">
        <parkstatus>
true
        </parkstatus>
        <parkposition>
            <raencoder>
$rastep
            </raencoder>
            <deencoder>
$destep
            </deencoder>
        </parkposition>
    </device>
</parkdata>
EOF


It will write the ParkData file automatically.
It's still a work in progress, it's in the right direction.
