Getting it to track at a set rate may be OK, but how to control motor reversals ( esp in DEC ) would be more effort than its worth.

And just for info re the manufacturing tolerances, i did the numbers on a meade wormwheel a few years back
With a 5" dia wormwheel, one arcsec of error at the point of contact with the worm is approx 0.00031mm.
Puts it into perspective how small the tolerances are

Andrew the EQ6 is a Chinese copy of the EM200 so I imagine fitting encoders to that mount would not be too difficult. The encoders on the EM200 are outside of the case directly attached to the worms (see pic below).
