I had similar problems for a while.

My guide camera is the Orion SSAG. There is a setting box that comes up in Maxim - one reduces noise and the other smooths guiding. I keep the smooth guiding setting off till I have calibrated. This does mean that the SNR can be a bit lower so subs may need to be longer depending on your set-up. With both on, I found that the stars would move on screen but Maxim couldn't pick it up.

Aim for SNR of at least 30 - I shoot for 40+. It seems to work fine for me now (touch wood)
