The extruder top cover V2 features enhanced functionalities of the extruder cover V1. The modernized version of the cover provides even more protection to the extruder cable. Thanks to the fastener included in the upper part of the cover, the extruder cable is tightly secured, right next to its connector where severe deformation can occur during the printing process. Also, the extruder top cover V2 makes material feeding easier through the redesigned hole for the material guide.
We highly recommend replacing the cover V1 with the cover V2. First, you need to 3D print the model available: here and follow these steps to upgrade the extruder top cover from V1 to V2.
