Centreing failure at step 3

Hi all,

Last night i couldn't get past a failure to slew at step 3 whilst platesolving. Previously It's all been working reasonably well and solving fine. I haven't made any changes.

here's a link to log file

thanks for any help with identifying the problem which was a showstopper.

I am set up with platesolve2 as main solve and ANSVR as failover. Result was same with both. Solves fine but fails at step 3

Just to add I was using 'Centre Now' to position the scope on the target before starting the sequence. This is my normal process when the unusual event of 'clear sky' happens and usually works fine.

best wishes
Paul
