I have the standard OK3 focuser that came with my N10 astrograph. I am finding that the Homefind routine only works sometimes. I have used the focus control in Autoslew and also ACC. Both software routines do the same thing. I press the Homefind button and the focuser slews all the way inwards and then keeps running. The position indication number in whichever software I am using keeps changing but the focuser is no longer moving. It appears to have reached its inwards limit.
Occasionally it does work and reverses out 2mm and resets the display to that value as expected.
I am concerned that the motor continuing to run while the focuser is not moving may damage the mechanism.
Surely the focuser has limit switches at the end of its travel?? If so it looks like they only work sometimes or else the focuser stops moving before it reaches the inwards limit.
The only thing I can think of to try is to increase the shaft pressure with the adjusting screw but I am not willing to do that yet in case I am missing something else.
