[QUOTE="a33, post: 1125367, member: 332642"] Well, I looked into this one. The good thing of this one is: - it starts with the zero-alignment, in steps 1 and 2, before the arc-tracking east/west in steps 3 and 4. I think that is the right order. - it doesn't copy the wrong procedure for steps 1 and 2, that is in the STAB HH100 manual; and is alas copied at several other internet pages. I've never seen a rectification by STAB. (BTW. If you have to do adjustments like these on a USALS setup, it might be that the USALS-zero is not at zero anymore. So following this above adjustment, you'd have to check if the dish should also be adjusted (rotated) on the motor axis a bit.) [B]The bad thing is:[/B] - in step 3 and 4: Usually after adjusting the motor axis elevation, you have to adjust the dish declination in the opposite direction, to get at the proper height again to reach the arc when at due south/north. So I would place an extra arrow in the picture. [B]- but even worse: I would do exactly the opposite of steps 3 and 4![/B] When you aim beneath the arc in west and east but OK at zero (step 3), the dish's declination is too great! So the [B]dish[/B] must go a bit upward, and the [B]motor axis[/B] should go a bit more downward. - so here, the STAB manual (which describes the opposite measure) is correct (as far as my knowledge goes...). BTW: The picture in this post is not bad (in Dutch): [URL="https://www.sat4all.com/forums/topic/354535-afstellen-diseqc-motor/?do=findComment&comment=2396047"]Afstellen Diseqc-motor[/URL] Though I'd start with steps C and D, and do A and B after that...... There are in fact many motor setup manuals. It is not easy, when you compare these manuals, to find that they sometimes contradict each other, and to have to determine which one is right. However, most motor manuals do have their own merit(s). I'm not sure which one would be my favorite. So in the meantime you'll have to cope with many manuals, and separate informative posts about modified motor angles, motor fine-alignment procedures, actuator triangle ratios, finding due south procedures, etc, etc... Certainly from reading all that, you'll gradually understand motor setups better and better.... Greetz, A33 [/QUOTE]
