Your screenshot is not very useful because the groups.io resized it down far enough that it's hard to read.
Anyway, you have 76 second periodic error just like me, and also everybody else.
PEC will not fix it.
There are a few possible ways to address it:
0) Send it back to Losmandy.? Get it back in an unspecified amount of time.
1) Reset the bearing blocks, as per Losmandy's Youtube video.? Maybe the block will realign and this error will be reduced.
2) Shim the block to change alignment (too much trial and error)
3) Michael Herman Belleville washer fix.? (This was the solution that finally worked for me)
As for DEC backlash, I have a very long post about how to adjust it

?alan137,
I have read your post and my backlash is similar to what yours is showing as very good worm mesh in the picture. Maybe I'm just being a little too picky on that.
Tracking on the DEC is pretty actually pretty good on my mount. Maybe the PHD2 backlash estimate is not quite accurate like some people say on these mounts.
I recently change the TVC from 0 to 10 and that seems to help.
I see the solution for you was the Bellevue washer fix, I take it you had a large 76 second error.
Was it just the washer, or did you switch out different bearings also.
What did that fix take it down to, is it noticeable in guiding or in the PHD2 log viewer?
I'm pretty sure I have the worms meshed satisfactory, it's just that 76 second thing.
Here is a picture,? I hope it shows, of the significant errors from PECPrep.
Thanks for the advice, all help welcomed!
