The mount does not seem to stop. The guiding will correct itself in 2-3 pulses after the 30 second phase and the mount continues to make drive noises. As far as did the mount receive a guide pulse, I don't know how to determine that. I know PHD2 produces a guide log that will tell me if it sent a guide pulse but I don't know of a corresponding log for the mount to tell me the mount received the pulse.

Tim, drive noises during guiding? What does it sound like?
The guiding behavior looks like backlash, possibly a poorly adjusted spring-loaded worm. Do you have any recent PHD2 guide logs? The ones you posted last year show what appears to be a typical backlash problem in DEC axis. Does RA behave well during guiding? Did you try to measure backlash using PHD2? What is the Gemini TVC setting set to?
