Hi Folks,
My mounts Dec gears have a discernible amount of backlash as a result of the motor being a fraction of a mm too far from the worm gear. I have previously reset the motor position to move it as close as its mounting bracket holes allow, but to perfect it I would have to file the motor brackets to allow it to physically sit closer to the gear wheel.
PHD2 backlash assistant says there is some 1662 ms or ~ 10 arc seconds play in the gear (see attached shot).
The SkyX Professional Edition with a 360 star model shows a discernible North South running streak in my pointing result - making me wonder again if this is a clear sign of backlash at play (see attached picture).
So my question (if I don't want to physically re-machine my DEC motor's bracket - which I will do as a last resort) - can this discernible backlash be accounted for best by setting backlash compensation in my mounts hand controller - or do I try and do this in The SkyX and PHD2 and/or other programs?
The Skysensor2000-PC that controls my Vixen Atlux has a backlash compensation setting between 0 - 999 from memory. It is currently set to about 40. Is my best course of parameter changes to:
- Set the hand controllers DEC backlash compensation to zero and try to adjust for all the backlash in TSX and PHD2 and other programs?
- Raising the hand controller DEC backlash until PHD2 and TSX Tpoint shows improved pointing and guiding?
- Biting the bullet and re-drilling the motors brackets until the motor can be correctly position?
If it is initially try approach 1 - is there a preferred way to instruct TSX to allow for DEC backlash and the same for PHD2 (although its wizard seems to detect it - not sure if it account for this determined backlash)?
Many thanks all!
