Quote:if you mesh the worm wheel/gear perfectly (i.e. no backlash) it becomes so stiff that the motor has real difficulty in moving the axis and maintaining tracking.

Quote: [John,I had this same issue, but only in my DEC axis. I was able to get a very good mesh in RA, so there is so little play and you cannot really feel it when the clutches are on and you try to move it a bit and the RA motor moves very quitely and smoothly without straining. In DEC it has been a bear to get it to mesh well enough and not bind the motors so there is no appreciable backlash. I keep meaning to email Ed about this, as I have gone over his video several times and remeasured all of the spacings. Maybe I am being a bit over particular about it, but I do not like the amount of backlash I still feel. The mount seems to work fine, it just is not as well meshed in DEC as it was from the factory. Of course the unlocked axes now spin like well oiled tops! I have no more stricture and it guides well.
