FocusLynx QuickSync TEC Installation Instructions - Revision 1
Page 8 of 10
FocusLynx Software Setup
Your QuickSync TEC motor is now installed. Consult the FocusLynx Quick Start Guide to install the
FocusLynx Commander software. Once installed, you will need to configure the FocusLynx Commander
for your new QuickSync TEC motor. Configuration within FocusLynx Commander will also configure the
ASCOM driver so that the same settings will apply when using auto-focusing software such as Maxim D/L
or FocusMax.
FocusLynx Commander Focuser Type selection
Select the FocusLynx FT Hi-Speed Focuser Type option first. If you find the pinion assembly is slipping
try the FocusLynx Hi-Torque setting. With stepper motors, speed and torque typically work inversely.
That is, higher speeds will usually result in lower torque. If you find your pinion assembly continually
slips contact Optec support (support@optecinc.com).
If 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 designed for
the unipolar motors in 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 TEC assembly. Contact Optec support
(
[email protected]om) if your focus motor cannot be adjusted without slippage or stalling. Sync the QuickSync position
With FocusLynx Commander running and connected to the QuickSync motor, manually set the focuser
near the center of travel. Re-engage the motor and enter 32,767 in the box next to the Sync button.
Press Sync and wait a few seconds. Test the In and Out movements to ensure proper operation.
NOTE: For some very long travel focusers like the TEC Large Focuser, Feathertouch FTF3545 and all the
FTM Micro Pinion Retro-Fits, you may need to manually re-focus and Sync again to utilize the full focuser
travel range. Each step corresponds to approximately 1 micron for the TEC and FTF focusers (much less
with the FTM) so the 16-bit resolution of FocusLynx will allow up to about 65mm of travel. In nearly all
cases, you will find that you will only need a few hundred steps to maintain focus once it has been
achieved.
