But it depends on if it's a general solution that is setup for synchronization, or a specific solution like Constant speed that never does any synchronization between encoders.
Here's my reasoning... As far as the register specs for the DC Motor controller goes, the control of the left and right motor "appear" totally independant.

Each motor (two per controller) has a duplicate set of control registers with open/closed loop settings, target positions and speed/power. So it's perfectly legal to run one motor in open loop constant power mode, and the other in closed loop, constant speed, run to position mode. No hope of synching here.

Plus the spec doesn't say anything about degraded speed in Run to position mode. The speed parameter is still 0-1000 degrees per second.

I guess my fiinal piece of logic is that if was going to do synching, why not ALSO do it in Constant Speed mode (even without a target end point). Seems like if it can do 100% in this mode, why not Run To Position?
