Re: Losmandy OPW Assembly

 

Check for side to side movement of the worm in the block.

Hello Everyone.

I installed the Losmandy one piece work assembly yesterday (fully assembled with the HP worm from Losmandy). The problem I'm having is I cannot get anything except a loose mesh without getting RA lag messages, or hard motor stalls.

I've worked around the worm gear to find the best overall performance, but no matter what I try I have to leave a fair amount of backlash between the two. The backlash is 3mm+ (estimated) at the end of the counter weight shaft.

The SST worms had less backlash....

My questions, for those who have installed the OPW, are:

1) How much backlash do you have?
2) Is there anything I can try to reduce the backlash?
3) Is this "normal" for the OPWB?

Also, the PemPro results show a signifncant reduction in the "76" error, but the overall P.E got worse. Before the installation the P.E. was 11~12 (+/- 6) arcseconds overall, and after is 20 arcseconds (+/-10). Not good.

Any insight?

Thanks.

Joe
