I'm glad everything works for you.
The speed value cannot be higher than 255 and now the driver lets you set maximum 250. So it's rather the problem of high gear reduction ratio for the motor than slow speed. I will increase maximum backlash right away. Checkout the sources in 5 minutes.
Let me add selection of various modes in a future release.

It looks like resetting the PWM did the trick. Nice work!

I had a chance to use it tonight. And hats off to you Kaczorek, the driver works beautifully.
All I have left to do is address a few mechanical details. Even so the autofocus routine did settle on a good focus after about 10 shots.
Thank you very much.

Joystick controls don't appear to be functional. Dialog will report Focuser aborted messages, but does not abort. Messages appear after reaching position. Focus In/Out reports nothing.

I will take a look at joystick controls. Abort focuser function is not implemented so it will not work.

Thanks Kaczorek. Take your time. This is just a report and I'm not even sure I will be using a joystick in this way.

Kaczorek,
I've run into an install problem. Can't obviously see what I've done wrong.
Start point INDI server already installed.
system update & upgrade performed.
wiring pi already installed - checked with $gpio -v returns version 2.32

Then running your compile from source script :
all steps run as expected with no errors until the last line
>make install
This returns:
CMake Error at /home/rob/astroberry-amh/build/libs/AdafruitStepperMotorHAT_CPP/tmp/libAdafruitStepperMotorHAT-gitupdate.cmake:136 (message):
Failed to unstash changes in:
'/home/rob/astroberry-amh/libs/AdafruitStepperMotorHAT_CPP/'.
You will have to resolve the conflicts manually


I can only think i've got a dependancy issue, introduced when I sudo apt upgrade/updated the system?

Also on further checking I note that there is a newer version of wiringpi - which have you?
Maybe i had an ADAfriuit library already installed within the other packages?

Also when I've started up the indi server again with:
indiserver -l /var/log/indi -f /var/run/indi -p 7624 indi_amh_focuser

i get
2017-06-14T22:59:42: startup: indiserver -l /var/log/indi -f /var/run/indi -p 7624 indi_amh_focuser
2017-06-14T22:59:42: open(/var/run/indi): No such file or directory.
2017-06-14T22:59:42: good bye

so it would seem the install failed to complete properly somewhere in the process? Before I reinstall everything from fresh, i wondered if there was anything obvious i'm missing, like a prerequisite?

Everything's OK. You need to remove libs directory from your build directory before every consecutive cmake run. The driver is using submodules and there's no easy way to do this. So you need to rm -rf /home/rob/astroberry-amh/build/libs everytime you recompile the driver.
Also make sure that you run sudo make install instead ust make install. Everything should work just fine when you follow these. If not, just let me know.

I'm a digital bot, I don't need any sleep ;) But seriously, You got me in the middle of imaging session and while it runs I often do some reading.
