Ok. I have tested all night, and found the following:

The backlash calibration procedure:

It is a great idea, however it is kind of cumbersome to use. If you use large step sizes in KSTARS for focus, it is difficult to detect the position at which backlash has ended. Plus atmospheric changes cause small changes in HFR readings to be reliable as a backlash detection method.

I use the graph created when doing an autofocus on K-Stars to look for the position you would expect to see the reverse function go to position and try and come up with a number that makes it stay within the predicted path.

I would recommend using a textbox to allow the user to fill in the backlash value.

The INDI driver moves the focuser to the target position plus the backlash offset. So the final Absolute position is target position +(-) backlash offset. This is not ideal.

I believe this is a limitation of the Esatto not having a proper backlash function.

To work around this the driver should re-sync the absolute position with the backlash offset, and then the driver should go to the target as expected. This scenario should work well.

Oh the temps are now properly setup. Motor temp is actually the motor temp and the outside temp should work fine.

Well you can download his forked distribution and then compile it on your Raspberry Pi.

Otherwise you would have to wait until it is added to the repository and you can do an APT update command.

Do you have experience with Linux?

I am not a Linux programmer, but I can follow directions and type commends. That's it.

Ok, so I finished testing the new driver and it is now applied to the GITHUB for INDI.

So, a couple of questions:

1 - Is your setup using a Raspberry Pi or Ubuntu remotely to control you setup?

2 - Do you have SSH installed and tuned on?

3 - Do you have access to root and it's password?

If you have these you can build / install from GITHUB. It sounds scary, but it's not at all. I can help you get it installed if you need help.

Let me know.
