Check The Filament Sensor Housing before the installation

Due to changes in the CR-10S posterior to our DDS for CR-10S product launch, Bondtech received feedback from customers informing us the original Filament Sensor Housing would not fit the new printer. For that reason, check the Filament Sensor Housing fitting first, before uninstalling the original extruder. If you have a new CR-10S model and bought a first release DDS for CR-10S, you will have to print a new mount bracket to fit your printer. You can download that new bracket here.

You will need :
