Guiding stops with Error 120 and Aborts Sequence

Hi, I could do with some help to work out what is causing an error I am seeing in my Sequences. It does not happen every night, but when it does it causes the Sequence to Abort. For example last night this occurred 2 hours into the Sequence, I changed nothing - just restarted the Sequence and it continued until dawn without an issue.

The error shows in the Monitor window as: A guide command is already in progress. Error = 120

A log extract is below and the shutdown starts after this Error 120 is recorded three times:

I have attached a screenshot but can get more logs if needed.

For guiding I am using TSX 64-bit with an ASI174MM Guide Cam. The Calibration message below is expected as I’m already happily calibrated and saw no reason to change it as all was working well.

Any thoughts?

Many Thanks, Mark

Mark this is an error from TSX.
Guide camera is busy with another command error is reported.
You can intercept the error in DragScript and restart the sequence.
Be sure to not save image by default in TSX settings.
Voyager retry to calibrate guide to exit empass but you ask to not calibrate in sequence.

Brilliant, thank you Leonardo. I’ll check my setting and hopefully get a chance to test out tonight. I did suspect it was TSX causing the issue.

It’s only happened about 3 times in 11 hours of imaging of M101.

Thanks again for the super fast support you provide.

Kind Regards, Mark
