The problem with closed loop (that I'm discovering first-hand) is that each axis is independent. The encoder does notice the missed step and compensate for it, but at the expense of time. As you might…

Here is the concept of oneshot PWM by Felix:
"normaly MWC workes with 488Hz periodic PWM witch mans one PWM cycle takes ~ 2.2ms and the value that need's to be send can just be updated after each cy…
