Required components: MK8 extruder and E3D Hotend are necessary. A 2-pz., 4x4, 5-volt fan is required. The original four bushings or four 15mm linear bearings for hardened barrels are needed. Thanks to jeeplvr for their excellent work. http://www.thingiverse.com/thing:734876 Instructions WARNING: Warping effects can be critical in these types of pieces, and any bending can cause carriage jams due to misalignment of the bearings. Print all parts on PLA to prevent warping effects. Printing recommendations: Two shell thicknesses are recommended. A 0.3mm layer thickness is suggested. A 6mm adhesion brim type is recommended. Everywhere support type (only for main body STL file) is necessary. Twenty percent infill is advised. Three millimeter top and bottom thicknesses are required. To use the original bushings, use the bushing holders. 1. Insert bearings into bearing guides. 2. Glue bearing guides to main body with epoxy before glue dries. Mount carriage on shafts and verify smooth operation. The idea is for pieces to dry with carriage mounted on bars, ensuring correct alignment. 3. Let dry for ten minutes. 4. Continue assembly of other parts. 5. Add EEPROM value -4.000 to Z home position to compensate for change in hotend height. 6. Calibrate bed. That's all. Print various materials without jams.
