Subject: thanks Sent: Tuesday, December 6, 2005 19:10:25 From: Eddie Walker (email@example.com) Hi Mike, thanks for your help. I calibrated the motors and trained both drives and there was a dramatic improvement. Now when I slew conterclockwise and let go of button its stops, and when I slew clockwise and stop then it goes counter clockwise about one tooth and then slews normaly. I probably need to do a more precise drive train. I did a goto to mars and with a 3x barlow and 10mm eyepeice, it stayed almost in center of eyepeice for about 25 mins. Again thanks for your help.

Subject: right ascension drive problems lxd55 Sent: Friday, December 2, 2005 19:12:33 From: Eddie Walker (firstname.lastname@example.org) Hi I have encounterd a problem with the right ascension drive wanting to slew to the west. If I slew to the east it will stop and right away move back to the west, and contine but very slow to the west.When I first power up I can slew and everthings fine until I enter time and date and alignment. I called meade today about a new right ascension unit. I downloaded the latest autostar version, even reset the handbox, tried a different cable. Nothing seems to work. Any suggestion would be appreciated. Thanks EddieMike here: Have you done a CALIBRATE MOTORS and TRAIN DRIVES? These cure most such problems, assuming it is not a mechanical problem. And I always recommend doing them after any Autostar ROM update.
Hi Mike, thanks for your suggestions. I tried them but no sucess. Ive got an extra motor that came with the mount, I may try to install it and see if it helps. I havent changed any ratios or anything I dont think that could be a problem. I guess I will order the ra unit from meade tomorrow, dont no what else to do. Thanks EddieMike here: Does the problem only appear in some orientations and not others? If so, maybe it is a counterweight issue.
Hi Mike, thats ok I know you are busy. I changed the motors yesterday and it didnt help. While I had the r.a. unit off, I hooked it up, went through autostar to the align section and it started to slew about a quarter inch, by looking at the gears, then slows back down to what I assume is a normal speed. This is what it does when it is installed on the mount. I adjusted the worm gear but that made no difference. Looks like to me its something in the control panel electronics. I changed handbox cables and it made no difference. Sorry to ramble on. EddieMike here: After you installed the new motor did you do a CALIBRATE MOTORS and TRAIN DRIVES? Remember, you have to TRAIN DRIVES on BOTH axes.
