Hi,

I have a MAG instruction linking a Virtual Master with a physical slave servo with a ratio of 3. Following the command pos.

Just wondering if the position will sync or if it's just a speed / distance relationship that is maintained.

I find that over time these two slowly get further away from each other. 3 revs of the slave should equal one of the virtual. But they don't track perfectly.

With the lock position does that get the servo physically back in a synchronous position with the master or not ??

For this application it needs the ratio but also has to start and stop in the exact same position as the master.
