Jack There are folk doing it but it is a bit different than the catchup you suggest. The reason a stepper falls behind is because it's being worked to hard. You can't work a stepper harder in order to catch up. What we do is reduce the speed on other steppers until the slowest one catches up to the rest of 'em.
I don't believe that there is a config that is setup for this. That would be a great contribution.
