(11-07-2021) Added the STEP-File of the Anet ET5 X-Carriage ----------------------------------------------------------------------------------------------------------- While looking for a visually appealing shroud design for my new E3D hotend, I came across Ammar Faridi's profile (ammaryasir) with many great shroud designs. I decided to modify his 'AYF Compact shroud for E3D V6' to fit my Anet ET5 Pro printer with my new E3D Lite 6 Hotend and my Touch-Mi ABL probe. The design should also be suitable for Anet ET4 printers. Contrary to the original design, the housing consists of a single body. The Hotend holder and the housing are separated parts. The Hotend holder is fastened to the X carriage of the printer and the housing with the fans is simply pushed down on from the top. This means that only the Hotend mount has to be printed from thermostable material. The housing, for example, can be made of easy-to-print PLA. The original fans can be re-used. The following instructions have been prepared to the best of the author's knowledge and belief. The realization is at your own risk. No responsibility is assumed for damage or injury. The modification of the hotend requires a printer flashed with Marlin firmware (recommended: Marlin 2.0) Please note that the E3D hotend in this design is placed higher than the original hotend. It may be necessary to adjust the bed to a higher position so that the nozzle can reach it. Required tools: M2 thread cutter M3 thread cutter Standard tools 1x M3x4 ISO 7380 pan-head screw (Probe Mount) 2x M3x8 ISO 7380 pan-head screw (Hotend Mount) 2x M3x12 ISO 7380 pan-head screw (Hotend Bracket) 1x M3x8 ISO 7380 pan-head screw + M3 hex nut (for Standard Probe) 1x M3x12 ISO 7380 pan-head screw + M3 t-slot nut (for Touch-Mi Probe) Assembly: The assembly of the individual parts can be taken from the enclosed exploded-view drawing. For the assembly, it is recommended to remove the X carriage beforehand. Take this opportunity to check whether the eccentric V-slot wheel of your printer has been mounted correctly. In my case, a washer was missing, so that the entire eccentric wheel was not sitting straight on the carriage (see also attached picture). -Cut the M3 threads for the hotend bracket into the hotend mount and attach the hotend mount components and the ready-assembled E3D hotend to the X carriage. -Move the X carriage back on the X axis. -Cut the M2 and M3 threads into the shroud body and attach the axial and radial fan with the original screws. -Slide the shroud housing onto the hotend holder from above. Make sure that the cables of the hotend and the cables of the sensor and the fans are in the designated channels and are not squeezed. -After all cables are reconnected, secure the harness to the strain relief with a cable tie. Firmware: In addition to the changes in the Marlin printer firmware for the E3D Hotend (see E3D Installation Guide), the new probe and bed center position must also be defined in Marlin: New Probe position. In configuration.h set nozzle offset to: " #define NOZZLE_TO_PROBE_OFFSET { -44, +4.8, 0 } " The z-value can be determined and set with the Marlin Z probe wizard (printer configuration menu). New bed center position. In configuration.h set Y min position to 0: " #define Y_MIN_POS 0 " In configuration.h activate manual Y home position by removing the //: " #define MANUAL_X_HOME_POS 0 " In configuration.h set the manual Y home position to -26: " #define MANUAL_Y_HOME_POS -26 " Touch-Mi Probe: In my design I use the Touch-Mi ABL probe from Hotends.fr, which I highly recommend for the Anet ET5 printer.
