Timeout on slew

#1

Post by yomamma »

I was imaging low in the south and did a meridian flip and the slew took over 2 minutes and it timed out.
I have a CEM120 and I have had to slow down the slew rate so the stepper motors do not grind because of the torque applied at the start of the slew.
I have wrapped the move mount command in an ignore error clause. Will that fix the problem if the slew takes too long? I also put a wait 60 seconds after to make sure the slew finishes before the sequenmce preoceeds.
Thanks

Hi Don,

yes, the ignore errors should handle it along with the delay - when the timeout happens, the sequencer just gives up waiting - it doesn't tell the mount to stop moving or anything like that.

The timeout of 120s is a value I came up with along the lines of 'surely it can't take longer than 2 minutes to get to the target'. Well, apparently it can, so I will increase the timeout to 180s for the next update :)

cheers,

Robin
