Subject: Re: LXD 75 Sent: Thursday, March 6, 2008 10:25:19 From: Dan Dolaptchieff (starwindmarine@gmail.com) Hi Clay, you got it right. I reset it each time. I switched the RA and DEC boards and the hi speed slew problem moved to the DEC side from RA side. I switched the 497 out and WALA the dec works fine in regular sidereal now .I dont have to go Tracking custom -999 any more. The Dec now has the problem of wanting to slew forever when looking for a alignment star. It also slews at max rate no mater what rate i set the 497 at. the Ra slews at the corect speed. the status display shows real time change now when slewing. the ra motor moves in small jerks when tracking in Sidereal is that normal? looks like the movement might coincide with the width of a encoder notch. The dec will not let me find a star or goto. I assume i need to replace that board then the mount should work perfect? Once again I appreciate all the help you have given me. I wouldnt have been able to get this far without your expert help. My wife imports some nice freshwater pearls w/ silver studs. I would like to send each of you a set for your lady. Nothing fancy. Please tell me your colour preference (white-black) and your address. Thanks much again. Hope to be sending you some pics of the jewel box this weekend Aloha Dan On Wed, Mar 5, 2008 at 9:01 PM, P.

When you are loading firmware, are you RESETTING the Autostar when you do? The problem you are having is not firmware related, so loading that is not going to help. RESET the Autostar under SETUP and let me know if that clears things up. What POWER SOURCE are you using? I suspect either your power source is bad or you have a bad DEC driver PCB circuit.
