MMU Calibration

MMU/AFC's are divided into three basic classes (type A, B & C) as described here.

Each type have similar but different calibration steps hence the separate guides.

Note

In all cases it is necessary to calibrate the toolhead dimensions. This not only provides highly accurate loading and unloading but also allows for automatic calculations of purge volumes, etc. If you have a toolhead sensor this is very automated! Alternatively the guide will aid in manual calibration or you can review documentation for user submitted values.
