M4F3 doesn't communicate since a few weeks

noralinn commented 5 months ago

Persistent issue since a long time. Pulling and reconnecting cable didn't help. Neither did changing the cable. Replace focuser?

Unit.Focuser{3}.classCommand('Pos')

ans =

   NaN

It may even be that the focuser motor is fried, but for what I remember that would be our first time. It may also be that the usb card is faulty, I remember we had a similar problem long time ago on M1. I don't remember if the card resurrected after a few days (static electricity?), or if we permanently hooked focuser and camera to other usb ports.

I'd suggest the following test still:

If the other focuser on the last04w works, connect F3 to that port.
close the matlab session in which you defined the Unit, open a new one
seriallist. It should report something like /dev/ttyACM0
F=inst.CelestronFocuser; F.connect('/dev/ttyACM0') (or whatever serial resource was listed) - what does it say?
if connect succeeded, F.Status, F.Pos, F.Limits - do they work?

Solved by Enrico.

Solution: PhysicalAddress of M3F3 was modified in the config file but didn't correspond to the port where the focuser is actually connected. The corrected config file is also committed on github.

Lesson learned, LABEL CABLES AND SOCKETS.
