Usage
2.3.1
Setup
Assume the motor unit was mounted to the
SteelTrack Diamond
focuser and connected to the
SteelDrive
controller. One or two temperature sensors were connected.
Zeroing
The first thing is setting a correct zero position.
•
If the homing sensor is used (the magnet is attached to the focuser), power on the device by
plugging in the attached power supply.
–
If the automatic homing was activated in the SteelGO software, Enter the
SET
mode by
pressing
SET
once (
LED2
is lit). Now hold
IN
for 3s. The focuser will then move
inwards until the homing sensor is activated, set its position to zero and subsequently enter
the
NORMAL
mode again (
LED1
and
LED2
are off).
–
If the automatic homing was no yet activated, but the sensor magnet is attached to the
focuser, use the
to move the focuser inwards until the home sensor is activated. The
focuser will then stop and set the correct zero position.
•
If the homing sensor is not used (no magnet attached to the focuser), manually move the focuser
to its most inward position. Subsequently power on the device. enter the
SET
mode by pressing
the
SET
once (
LED2
is lit). Now hold
IN
for 3s. The device will set its internal position
to zero and
NORMAL
mode is entered (
LED2
is off).
Set maximum travel limit
Depending on the whole telescope setup, the desired maximum travel limit may vary. In order to
configure a save travel range, move the focuser outward by pressing
OUT
. Once the desired
maximum is reached, enter the
SET
mode by pressing
SET
once (
LED2
is lit). Now hold
OUT
for 3s. The maximum travel limit is saved and
NORMAL
mode is entered again (
LED1
and
LED2
are off).
If the limit is to be extended above the current limit, the
NO LIMITS
mode needs to be used (with
care!). Enter the
SET
mode by pressing the
once (
LED2
is lit). The hold
again for 3s until
LED2
is blinking fast. Now the limits are ignored. Travel with
and
to the desired new limit.
Then hold
again until
LED2
stops blinking (we are back in NORMAL mode,
LED1
and
LED2
are
off). Press
again once to enter
SET
mode (
LED2
is lit), then hold
for 3s in order to save the
new limit.
2.3.2
Focusing
The intended workflow for focusing is:
•
Find the approximate focus position by traveling fast in
NORMAL
mode.
•
Use the
JOG
mode to limit the range of the best focus to the size of one jogging distance (can
be configured, default approx. 0.05 mm).
•
Use the
SINGLE STEP
mode to find the best focus position.
