Thanks for the information dmulheimer.

So does S3D allow you to chose relative positioning somewhere?

Watching it print I certainly didn't see anything resembling fast.
S3D does have settings for retract speed and slowing those way down didn't make any difference (listed in my tests). In fact at 100mm /min the x and y axis had to visibly stop and wait for the retract to finish which is why I stopped the test.
And, even if it was missing steps in the extruder, how does that effect the x or y axis?
