I'm making some tweaks to use it with the Prusa quad MMU. One thing I keep noticing are extra extrusions that are occurring between switch tower and supports (using S3D to slice). \r\n![screenshot from 2017-12-14 12-02-28](https://user-images.githubusercontent.com/28326982/34004845-08bd0d3c-e0c7-11e7-914e-c46c920976f2.png)\r\n\r\nIt seems in this case that it begins the un-retract before moving to position.
