Re: RA guiding awful after upgrade


 

A tiny amount of wiggle in each axis is normal.

Without any "lash" (aka wiggle, slop, choose your word) in one position (location on the worm) there is risk that the gears will bind on another.
The center of the worm teeth pattern is never exactly (we're talking thousands here) at the center of rotation of the axis. Want that? Spend a lot
more money.

Most people overdo trying to get backlash out of their mounts. Usually a fool's errand, caused by their desire
for perfection without spending tens of thousands on a mount.
?
When I adjust mounts I always to try to be able to just feel the wiggle but not see it or hear it (at high speed).
The human hand is a very sensitive instrument as is the ear.

I seriously doubt that is your "problem". And if you are satisfied with the imaging performance that is all that really matters.
More than one person has created problems for themselves while chasing perfection.
?
The fact that the "problem" appears only on one side of that mount (so it seems) points to something with weight/balance, or cabling.

I run my G11 off of WiFi using OnStep normally. I occasionally use USB but then it goes directly from the PC to the mount controller and that isn't very often.
So usually I just have one USB 3.0 running to the camera which has a built in hub. The guider and (when used) focuser connect to that so there is only one wire
from the PC to the mount and one power line to the camera cooler/hub. The mount and the PC each have their own power source.
That way I don't have a lot of wires running around to trip over between the PC (on a small table) and the mount. And minimal wires to drag the OTA..

Just the advice of an old, old, dog.
