Ok the optical train looks ok to me.
But is this your only train? Maybe you can try to add a secondary train for your guiding setup without a mount in the mount field. And put your imaging setup in this primary train.

I had a primary train just for my imaging setup and the train in the screenshot as secondary.
For troubleshooting I have created a new profile and added only the train with the guiding equipment to avoid other sources of errors.

Ok i understand.
Then unfortunately I can't help. I hope someone sees an error in your log.
My error was the same with a wrong train configuration.

Hi Alex,
if I understand your log right then is your mount pointing at Polaris. That's definitely not a good position for guide calibrating.

Take a position somewhere close to the celestial equator, ideally close to its intersection the meridian (not too close to avoid a meridian flip)

Hi Wolfgang,

you are right, had a little miss alignment. Have fixed that.
Please see the new log.

OK, with that position calibration should work, but obviously It doesn't. It seems when EKOS tries to reverse the RA motion after three successful steps, moving back has only effect in one direction.

The first three steps RA increase the x-axis and decrease the y-axis positions:

But when it reverses the direction, the y-axis position still decreases:

Hm, now we need somebody with an EQ-mod mount...

Hi Wolfgang,

is your suggestion to compare my logs with a log from an other EQ mount ? I could ask someone with an EQ6-R mount to generate logs and send them to me. What do you think ?

Right, we need somebody with EQ mount knowledge to take a closer look at the low level INDI commands.

Meanwhile, you could also give PHD2 a try. Maybe PHD2 works with your INDI setup.

Hello,
I have also some issue with V3.6.3.
The setup: iOptron GEM28, finder 9*50 with a Player One M-Ceres.

The calibration fails with the internal guider or PHD2, made on the equator, with guiding by the mount. I try with ST4 connection, no issue !
I would prefer to guide by impulse to the mount instead by ST4.

Hi Guys,

have tried guiding with PHD2 and result is the same behavior. The calibration fails and I los the guidingstar.

Have also tried it several times with ST4 but no change.

I have an HEQ5 Pro mount and saw similar if I skipped accurate polar alignment. Did you do that as part of setup?

I also run the box in your guide setup at 32, not 128. Just big enough to cover the guide star.

I'd change your guide train to secondary. My trains are set up as below:
