…greater than nominal speed - as seen with fast extrude/retract moves.

Looks simple, and your explanation is great. I will test this next week and merge it if I do not find any problems. This seems to be vital for dual-extrusion, as retraction was causing a lot of headache for us their. |

It mostly affects fast retraction moves, but could affect any axis with the right combination of speeds and accelerations.
