MATERIAL DRIVE CONTROLLER
Each individual material bay has a material drive controller. The material drive controller feeds filament from a
material bay to the head. The material drive controller is located on the back side of the material bay and
contains a small 12 VDC motor which drives filament up to the head. The material drive controller is a non-
serviceable item and is instead replaced along with the replacement of a material bay.
The material drive controller contains a mechanical filament present switch which detects the presence of
material within the material drive during the load and unload process. This switch also detects errors. If the
material drive controller detects that filament has broken within the material bay or the end of filament is
reached, the printer will pause to allow for recovery.
