If the payload is properly balanced, and the behavior
persists, check the spring plungers located inside the
worm-block assembly housing. The worm block covers
are the “smiley-face” shaped plates that are attached to
the gear covers. Once removed, you will see the worm
drive for the axis. There are one or two small spring
plungers that can be adjusted to decrease the pressure
between the worm and gear.
The mount cannot be
homed using the
joystick.
Homing from the joystick takes a bit of practice. The control
system is looking for two button presses, separated by at least
one-tenth of a second. One of the most common causes of
homing failure is when the joystick is moved unintentionally
during the homing procedure. Any joystick motion in either
axis while homing will cause that axis to abort the homing
procedure.
The best practice is to use TheSky6 Professional Edition’s
Telescope > Options > Find Home command to home the
mount.
During cold
temperature operation,
the mount emits an
audible “vibration”
sound while slewing.
A resonance between the worm and gear may occur at colder
operating temperatures, which is the cause of the sound. To
eliminate the vibration, remove the right ascension worm-block
cover and carefully place two to three drops (no more) of 3-in-1
household oil on the worm-gear interface. Also see the section
“XSlew Speed Adjustment (Temperature) GroupX” on page X74X for
additional cold temperature operation suggestions.
Mount cannot locate
the Home Position in
one or both axes.
The Paramount ME contains two optical sensors that are used
to detect the Home Position. If homing fails, check the
following:
The homing sensor cable is plugged in backwards. Have
you altered the internal wiring recently? If so, make sure
you’ve plugged in the cables correctly.
The homing sensor cable is unplugged or unseated from
the MKS 4000 electronics board. If the cable gets
snagged or pulled by other cables (normally this occurs
when customers add cables through the mount), then
homing could fail.
The optical homing sensor is "blocked" (usually from
over greasing) so the mount cannot detect the Home
Position. Has the mount been greased recently? If so,
you’ll need to remove the homing sensor (for the axis
that fails) and clean the sensor.
Check for rodent invasion inside the RA or Dec box.
Mice seem to have a taste for internal Paramount ME
cabling, and have caused significant damage to many
unattended Paramount MEs.
