Focuser Settings
Maximum Position: Value is used by the
Absolute Focuser Type (see below).
Maximum Increment: Maximum number of
“steps” to send to the nSTEP at one time.
Generally used to limits the number of “moves”
an ASCOM autofocus application can execute
during each call to the usb-nSTEP ASCOM
driver.
Step Time On (ms): Sets the duration of a
“step”. Valid range is 1-250 ms.
Focuser Type
Absolute: Select Absolute Focuser Type, rack
focuser all the way in (to 'Home') and then press
Reset Position. The gcusb-nSTEP software will
will set the racked-all-the-way-in position to
00000. Absolute Focuser Type limits focuser
position to between 00000 and Maximum
Position in ASCOM applications.
Relative: Does not enforce limits on focuser
position. Uses Maximum Position value to set
the current position to half the max position
value, when you press Reset Position.
Reverse Direc: Reverse In/Out directions to
reflect peculiarities of focusers and focus motors.
Half Step: Energizes 1 or two coils at a time,
doubling step resolution.
Full Torque: Highest power mode, two coils
always energized.
Coils Off: Turn coils off after stepping to save
power and reduce heating of the stepper motor.
Only use with a gear-head stepper a non-
gearhead stepper may slip lifting heavy loads
