Many thanks Gina!

Thank you!

The auto-focusing beta is here Anyone that wants to join? Take a look here: http://stargazerslounge.com/topic/222399-beta-testers-needed-episode-2/?hl=%2Bauto%26%238208focusing

I'm giving my best to release a beta version of the APT auto-focusing somewhere in the next week

Aaaah that one I have it in my To-Do list but auto-focusing is on the top

Dave_D, give some more explanation about the idea

Sorry, I didn't struggle with the driver setup yet

The prototype was made with Ardoino Mega kit. We had plans to release a How-To-Do-It documentation, to publish the sketch and the ASCOM driver but none of us found the time Whoever I'll be happy to share all the information and experience you need In the ASCOM documentation there is no word about negative position, but in the same time it doesn't provide possibility to define the minimum position. It expects to be 0... From the client applications like APT is expected to provide safety for the hardware and not attempt to move the focuser to extreme positions because this can cause to hardware damage and the only feedback is the value of the position property...

Dave in our project we store the position in the EEPROM storage, which makes the things much easier Because this memory has limited life, there is a timer that is started when you push the button and after a certain time it checks if you still hold the button, if not it stores the position. With the ASCOM driver it is easier. After the Go To command just write the position One more trick is that after storing a position I read it back to be sure that it is stored correctly and if the memory is corrupted am starting to use a new one With 100k average "write" cycles and 2 bytes for position (0-65535) you can store 2.5 million position changes in just 50+2 bytes The two bytes are to keep the address where position is stored... Park/Unpark feature is very handy and even easier to be implemented
