I have a joystick connected and went thru the procedure described in the tutorial.
Everything goes well, i can see motion on the all the motion tabs. i have button 5 defined as park and button 6 as unpark and even that is done. I can see that in de status of the mount.
But what is not working is that how long i move the joystick there is totally no movement of the mount.
'Joystick' has to be running as an Auxiliary INDI-Driver. And furthermore it may have to be enabled as an option in your mount driver as well. That is certainly the case with the EQMod driver.
