Same weird behavior for me. I have restarted imaging yesterday after several month break, and now I can't get my EQ6 mount to work as expected and make point to the desired target.
I get this behavior with the mount connected to a pi2 or a pi3. Same behavior with both kstars 2.7.8 on ubuntu and windows from the client side. On the server side, I get this weird behavior with both a rather old indi version (09/2016) and an updated one.
I tried it with no success.
Then I did a very simple test, which consists in pluging my synscan hand controller onto the EQ6. The hand controller won't initialized anymore, so I think my problems are due to a hardware failure and my EQ6 pcb is dead. I have already ordrered a new one.
