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
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
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
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
maximum is reached, enter the SET mode by pressing SET
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
LED2 is blinking fast. Now the limits are ignored. Travel with
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
new limit.

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.
