FocusLynx QuickSync Installation Instructions - Revision 2

If f the motor begins to stall you may hear a buzzing or chattering sound. First, try the
FocusLynx FT Hi-
Torque
selection. In cases where there is exceptional friction in the pinion assembly you may need to
loosen the internal tensioning nut slightly. Alternatively, you may try selecting the
FeatherTouch Motor
Hi-Torque
setting which operates the stepper motor at an even slower rate. This setting is similar to the
unipolar motor settings for the original Micro-Touch and Feather Touch Motor assemblies shown below,
but will also work well with the bi-polar motor used in the QuickSync FT assembly. Contact Optec
support (
) if your focus motor cannot be adjusted without slippage or stalling.
Sync the Zero position
With FocusLynx Commander running and connected to the QuickSync motor, manually set the focuser
to the beginning of travel (all the way IN). Re-engage the motor and enter “0” in the box next to the
Sync button. Press
Sync
and wait a few seconds. Test the OUT and IN buttons to ensure proper
operation. If the focuser moves in the wrong direction you will need to check the Reverse box in setup.
NOTE
: Effective with version 2.0 of FocusLynx Commander software and firmware, long travel focusers
like the FTF3545 and the FTM Micro Pinion Retro-Fits can move throughout the entire travel range
without the need to reset the zero point. Refer to the FocusLynx Commander Help documentation for
additional details for configuring the step size, step range, and “Sync” technique for best results.
