This upgrade allows Da Vinci 1 users to adapt a genuine E3D V6 hotend and MK8 extruder into their Da Vinci 1 3D printer. UPDATE 3/22/15: Due to limited space, issues have arisen with the Teflon tube and fitting that inserts into the top of the hot end. For details, refer to the instructions. I now offer fully machined hardened X-axis shafts. UPDATE 3/22/15: I've modified the carriage to accept a retaining bracket for the hot end and also added a retaining bracket for the hot end. UPDATE 3/21/15 8:50pm pst: I've replaced the carriage file with one that features a better cooling duct. Instructions: Hotend Teflon tube fitting clearance issue: A possible solution is to remove or cut off the tubing fitting flush with the top of the hotend and insert the Teflon tubing directly into the hotend. The required Teflon tubing has a 4mm OD, and it should stick out of the top of the hotend just enough to be inside the 6mm threads of the MK8. The ID of the threads in the 6mm hole (about 5mm) is close enough to the OD of the Teflon tube (4mm) to keep the tube centered. If the tube is loose in the threads of the MK8, you can wrap a piece of tape around it for a better fit. Print on the right side for better print results. Depending on how accurate your printer prints holes, the bearing holes may need to be drilled or reamed to fit 15mm bearings or 16mm bearings. The bearing holes are drawn at exactly 15mm. Permanently glue the belt grip into the carriage with acetone. Linear roller bearings require old rods for brass bearings to be replaced by hardened rods or the roller bearings will destroy the old rods.
