Hi JohnB,
Great to see the problem solved.
Although I’m a little late in coming into this post I would like to add more information for others who may encounter some problems.
The ‘Pegasus Focuser Driver’ is their Native Driver and the driver that should be set up first, not to critical, but may solves problems down the track of confusion.
SOFTWARE:
Connect power USB etc.
Start up the Pegasus Native driver.
Select settings.
CONNECTIVITY :
Name: What ever you like.
Device: The connection to you computer.
Preset Steps: Leave as is unless you have a need to change them.
Temp Sensor C/F: What ever suits.
MOTOR SETTINGS:
Max Speed (Presets)
Pegasus Motor (Accurate) The motor turns at a very slow pace taking longer to move in or out.
Pegasus Motor (Faster) The motor turns at a faster pace less time taken for same distance less accurate.
Custom You have the choice of setting the MAX speed for your focuser movement.
Value: Set Value of your choice. I have custom set mine to "250".
Set: This information is programmed into the Controller Hub EEprom Memory.
This will become your default speed.
New Position: (Reset Motor Position)
This is the most important Option to set the "0" position of your focuser. Use the motor control knob on the hub and move the focuser in as far as it will go or to a position that you feel is safe to prevent damaged if using a Rack & Pinion Focuser. You do not want to drive hard to either end of the focuser as this can cause damage. The Crayford does not suffer from the same problem as the focuser will slip. However, it would be wise to give it some free play as well.
Example : Use the motor control knob on the hub moving the focuser inwards until it is about 10mm from the end this would be number “1” position on my focuser. My telescope Esprit120 has a Rack & Pinion Focuser so care needs to be taken when setting up. Type in “0” then select ‘Set’. This information will be programmed into the Controller Hub EEprom Memory.
Reverse Direction :
Depending on how your Pegasus Focuser has been attached to your telescope will determine whether a forward movement moves your focuser inwards or outwards. Select this option if your focuser is moving in the wrong direction to what you would be expecting.
Limit Position: ON/OFF
Turn on the ‘limit Position’. The purpose is to prevent the focuser from going past the Min and Max position set. Therefore, will not go less “0” or will not go past the Max set.
Min :
You would normally set this to "0".
Max:
This would be set to the Max amount you want your focuser to come out. In my case I have a Maximum of "28500", so I have set mine to "27000". Giving me a safety margin of "1500" steps before the focuser would hit the end of travel.
Backlash Compensation: - Steps: " ".
This value can be left at ‘0’ unless you feel you are experiencing backlash. I have measured that there is about 90 to 100 steps of backlash combined in my Pegasus focuser and focuser Rack, so I have set mine to 90.
Rotary Encoder: - Enable Knob: ON
This is personal preference whether you have this on or not. It just means if you wish to alter the focus manually at the Focus Hub then this option needs to be ‘ON’. Other wise it will have no effect.
ASCOM DRIVER
Other then the Focuser ‘Reset Motor Position’ “0” all other settings need to be entered into your Ascom Driver.
The reason you got a figure of”934465” was due to the value set in the ’Start from Position’ “65534”.
The option, ‘Start from Position’, can be a bit confusing in the Ascom driver, it allows you to set a new focuser position value. If the focuser is at position “0” and you enter “25000” this would then be the new value for that position. Leave it ‘un-selected’ and “0” as the value.
