The last two weekends during the two star alignment the Autostar has consistantly missed both stars by at least 10 degrees RA, usually more, and the alignment always fails after slewing back to the alignment star and pressing ENTER.
This just started two weeks ago and I've been slewing the scope around manually. Have you heard of this happening all-of-a-sudden like, or have you experienced it yourself?
I just got off the phone with Meade (William) who thinks the encoder wheel may have failed on the RA. I explained that I've already been over the mechanicals of the mount and performed a drive training and calibration. When that failed, I did a hard reset and started over. Same problem.
Meade is sending UPS to my house to pick up the mount and the tripod for warranty replacement.
I gotta hand it to Meade, their mounts do have problems, but their customer service is first-rate.

It does sound like an encoder problem. I had one DEC motor assembly that would always overshoot dramatically. Couldn't find anything wrong with it and the encoder looked fine. It was so bad that drive training didn't work properly with it. Meade sent a new motor and all is well.
With a newbie, that's a common complaint and an easy fix - 15 degrees in RA is a one hour time or time zone (or DST)error. Since you did a reset you obviously re-entered everything, so you would have caught that.
I don't know whether Meade is ever going to make any money on these; their efforts to support 'em must be costing them a mint. They ARE supporting 'em, though, and quite well.

I thought about the time difference, but I didn't want it to be a half-a$$ed set-up by moving the clock back an hour on it or changing the DST to "NO".
I'm really glad they are taking care of this for me. For the longest time, I suspected that the mount was not new-in-the-box, but I can't prove that. The azimuth adjustment scews in the mount are loose and there were paint touch ups on the mount casing. In addition, the worm gear mount block center screw was stripped.
Hopefully they are not going to send a re-furbed mount to replace the one I have now.
