Hi David,

I've done this now and the V2 ASCOM driver is now reading Astro-Physics V2 Driver: v.5.30.10, 1200GTO
GTOCP3, Firmware: V2

However, the slewing behaviour is still the same: in the driver, a move rate of 12x gives a sensible result, but 1x
and slower are much faster than 12x.

Some of the changes in 5.30.xx involved changes to the move rate commands for the GTOCP4 and don't apply to the GTOCP3, which is now many years out of production. So, please try 5.21.xx as I suggested. You can install this version directly over 5.30.xx. Here is the direct link:

Thanks for the reply Ray.

Since you mentioned the firmware it occurred to me that maybe I should install the version V2 ROM that I bought
some time ago but had not got round to fitting.

This problem didn't start with the latest version of the ASCOM driver. It started randomly. This makes me think it is
more likely to be a hardware issue.
