Ive reported this earlier, but had no response. The AOX very randomly doesn't start correctly on first power up. When the fault occurs, I can exercise the AOX in CCDOPS and movement is reported, however no noise comes from the AOX. In this state, if I try to calibrate in say CCDSOFT, the AOX doesnt move the star and fails the movement calibration routine. Ive now seen this with the Maxim trial version 6.12, whilst evaluating ACP. The way to fix this is to cycle the power to the camera. For a manual user, this may not be such a problem, cycling the cameras power to wake up the AOX, but, in a remote circumstance, and under a automated session, this will see the session's data being affected as the auto-guiding routine continues with only bumps to the mount. No error gets reported that the AOX isn't moving. I now turn on-off-on the cameras power at the beginning which seems to solve the issue. What can be the problem?
