Tronxy X5S Flexion E3D V6 Retrofit Extruder Mount/Fan Shroud

THERE IS AN UPDATED VERSION OF THIS MOUNT! Follow this link... https://www.thingiverse.com/thing:3000014 This is a mount and fan shroud made to fit the Flexion Extruder with an E3D V6 Retrofit Hot-end using a slim 17HS4023 extruder stepper motor mounted with a direct drive setup to a Tronxy X5S printer using the original hardware, original 40mm blower part cooling fan for the Tronxy X5S, and the snap-on 30mm heatsink fan that comes with the E3D V6 Hot-end. This mount will allow you to utilize the existing gantry system belt attachments designed on the newer version of the Tronxy X5S where the belts are running parallel (unlike older versions of the Tronxy X5S where the belts were not parallel causing binding issues with the gantry system). So far I've printed over 30 hours non-stop successfully with TPU filament. See below for my comments on printing with ABS... Assembly tips: - Disassemble your E3D V6 hot-end completely (even removing the heater and thermistor wires). - Remove the original stepper motor from the printer. - Mount the slim 17HS4023 extruder stepper motor to the printer using the original screws. - Connect the stepper motor wires according to the diagram above. - Install the new mount and fan shroud onto the printer. - Calibrate your extruder to ensure proper alignment. Note: This stepper motor wiring differs from the wiring of the stepper motors that come stock on the Tronxy X5S printer. The "controller board end" of the stepper motor wires are the same, but the "motor end" of the stepper motor wires need to be wired different in the following order reading from left to right while snapped into the stepper motor with the drive gear of the motor facing toward you and the connector pointing up connecting into the "bottom" of the stepper motor. Original Tronxy X5S Stepper Motors: 1.) Red 2.) Empty 3.) Blue 4.) Green 5.) Empty 6.) Black 17HS4023 Slim Stepper Motor: 1.) Red 2.) Empty 3.) Black 4.) Blue 5.) Empty 6.) Green I was able to use the tiny flat head screwdriver that came with my Tronxy X5S to pry up on the white plastic pieces on the bottom side of the connector to remove the wires from the connector, allowing me to snap them back in accordingly. Also, you will have to reverse the E0 stepper motor direction, and I used 102 steps/mm in the Marlin firmware settings for this Stepper Motor/Extruder combo and so far it works beautifully! I came up with this number using the following formula... (Steps Per Revolution) x (Micro Steps) x (Gear Ratio) / (Hob Bolt Diameter) x (Pi) usually found in manufacturer specs (there is no gear) (measured this with micrometer) (200) x (16) x (1) / (10) x (3.142) (3200) / (31.42) = 101.8 which is roughly 102 steps per mm A great tutorial for this can be found at this link... https://e3d-online.dozuki.com/Guide/Titan+Marlin+Configuration/35 UPDATE: As stated above, 102 steps/mm worked great printing with TPU flexible filament. After switching to using ABS filament, I noticed some major over extrusion. After manually recalibrating my extruder, I came up with 90 steps/mm. For anyone who does not already know how to do this, there is a great instructional video by Matter Hackers in the link below... https://www.youtube.com/watch?v=X3A9Ir2SreI Once you upgrade your Marlin firmware to 1.1.8 you can change this in the options directly on the Tronxy Display under "control" then under "motion" in your settings. Here is a link to THE BEST TUTORIAL I HAVE FOUND TO DATE on how to flash firmware onto the Tronxy X5S WITHOUT NEEDING AN ARDUINO UNO. Contrary to popular belief (at least with the new version of the Tronxy X5S) you only need a computer and the USB cable that came with the TRONXY X5S printer. http://www.customize-3d.com/flashing-tronxy-x5s-factory-control-board-usb-cable-only.html
