I have had some problems with the smooth operation of the rec drive. Any easy way to put some lubricant into the worm and wheel. I did put some oil behind the black covers of the worm bearings. It did help, but I think it's not enough. Thanks for the information.
Hello. Maybe it is an offset problem. With Android phone I didn't have any problems. With Win 10 laptop, for some reason, there is sometimes a several offset error in the initial position. Go to information, choose coordinates and check initial values. I solved the problem by first selecting az, then disconnecting and selecting eq mode. The offset error was reset! Have no idea why it arises, but in this way you can reset the error. Found by accident. Cheers.
