Presets: It is possible to recall stored presets. Select the desired telescope from the
drop-down list. Then the right-hand column shows the configuration data of this
telescope. Click on the
"Use preset" button to load the data to the left-hand column,
where you can modify them if necessary. Use the "Save Preset" button to save the
contents of the list, then select "Save to device" to load the data into the FMC .
Click on the "New" button to create a new list.
Write the name of the new telescope, and then click "OK" to save it. Then press the
"Save Preset" button, and it will be filed to the list of configuration data.
Path to the file to store the data:
"c:\Users\xx\AppData\Roaming\Lacerta MotorFocus\ settings.json"
Save this file to another location or make sure that it is not deleted during an Ascom
driver update.
Values that can be set on the Ascom Setup panel:
Backlash:
Its value should be 0 if the compensation is to be used from a PC
program. If we still want the FMC to perform backlash compensation, enter
the desired value here. The FMC performs backlash compensation using
the uncounted step method: for every change of direction, it takes the step
specified here in addition, so that the steps are not added to the display of
the Position!
Current Holding:
The value of the holding current is in milliamperes. In the case of the FMC,
this value can be increased to 1000mA, but in practice, we should not use
a holding current higher than necessary, in order to avoid undue heating of
the controller. 160-200mA is sufficient in almost all cases.
CurrentMoving:
The value of the moving current is in milliamperes. In the case of FMC,
this value can be increased to 1000mA.
PositionMax:
The value of the maximum available position. It can be a maximum of
250,000, which means a 250m path with 0.001mm steps, which is
