You did tighten the DEC knob? If you did the altitude gears (a worm gear) is not engaing properly. You can either return it to Meade for repairs or attempt them yourself.I would also check that you have fresh batteries and that the UP button on the hand controller is not broken.

I have an ETX 80 and the motor runs but does not raise the tube, it lowers it and it slews left/right. Any ideas as to the problem. Many thanks in advance!!!


Is the clutch knob tight? If it is then something is broken inside the DEC clutch, causing it to slip.Meade can repair these -- call customer service:http://www.meade.com/support/index.html

Azimuth motor gearing problem


Sounds like it could be that the worm gear is not meshing Look here for guidelines in the internals

Azimuth motor gearing problem


I also purchased a used Meade ETX-70, only to find it had the same problem with the rotation axis motor running but no movement. After removing the bottom cover, I found the motor w/worm gear would not contact the main rotation gear. I solved the problem but purchasing a small 3/8x3/4x.032 spring that I had to custom fit to hold the motor w/worm gear against the rotation gear. Take caution not to have the spring apply to much pressure or it will cause to much drag. To gain access, remove the bottom round cover(it will just pop off). Then use a small .05 allen wrench to remove the set screw in the horizonal chrome lock. The chrome lock fits over a 1/2" bolt. By removing this bolt you will remove the washer/bearing assembly. After removing this, you will see a nylon nut, use a 11/16 socket to remove. Becareful, it is a fine thread and you don't want to cross thread it! After you remove this, you will be able to remove the bottom housing, which will expose the motor and gear. You should be able to see what I am referring and where to place the spring. If you can make it this far, then you should be able to install the spring. I used a little small dab of Gorilla glue to hold it in place, since the spring will have enough constant tension to keep it from moving. I'm not sure if this was a design flaw, but I got no help from the Techs at Meade, only that they would upgrade to a ETX-80 for $149.99 plus shipping. Hope this helps.......

I have a Meade ETX-70. When turned on, the handset says there is a Motor Unit Fault: Motor failure detected due to moving handset between scopes, low battery level, obstructed or overloaded scope. I've replaced the batteries with fresh ones, with no luck. I do not understand what they mean by "moving handset between scopes". (Note: twice the motor unit engaged and the telescope rotated on base while warning was scrolling across handset,


This is usually caused by low battery power-- as the hand controller reported. DO NOT USE rechargeable batteries they do not have enough volts. Use alkaline batteries only.This can also be caused by a broken gear or a failed internal motor. You can return these to Meade for repair.Here is the contact number:http://www.meade.com/support/index.html

MEADE ETX 125 Motors have stopped


The ETX125 is notorious for bad motor control. Weasner's Mighty ETX web site has links to repair centers that are more reasonable than Meade. They also have a QA section to assist with diagnostics.

First time using the mead etx 60at. I turned it on and set the date / time / enter. Then set it at north and horizontal,enter. It asked if i wanted the easy alignment, I said yes. I said searching. Then it said the name of astar and said it was slewing but the telescope isn't moving.


Did you lock down BOTH clutches? You should have Calibrated motors and trained drives before you actually tried to do a goto.Read this manual completely:http://www.meade.com/manuals/TelescopeManuals/ETXtelescopes/ETX-60-70AT%20manual.pdf

I have an issue on my meade ET90 AT. I have a motor failure message after the telescope try to find a star. Now when I turn on I received a message from the autostar to press 0 or mode in both case it start the test motor and appear the message Motor fault. I change the batteries but it doesn't change the result. When I turn on and I received the message "0 or press mode" if I try to push the arrows button the telescope move right and left but no up and down. I called the meade customer service and after 30 seconds they told me to bring the telescope to their repair center. Thanks


Try this.1. Do a RESET on the hand controller.2. Reenter your Site, Date, and Time.3. Calibrate MotorsNow see if that fixed it. If not it will need to be returned to Meade because a gear or circuit is broken inside the scope.
