E3D Titan Aero mount --- Using a Titan Aero adds width to the X assembly and reduces X travel compared to standard design; the amount depends on motor and fan used. With 20.7mm motor and 7mm fan I am limited to 295mm of travel in X with approx 1.5mm clearance either side. My frame extrusions and shafts are based on 300x300x300mm in configuration spreadsheet. That gives an idea of how much X travel to add for anyone planning to use this extruder. Some examples: 20.7mm motor, 10mm (stock) fan - add 3 + 5 = 8mm minimum (I would round that up to 10mm) 25mm motor, 10mm fan - add 3 + 4.3 + 5 = 12.3mm (or round up to 15mm) E3D_TA_X_Carriage There are two additional bosses on back side of carriage for threaded inserts; these are used to mount fan duct. If you don't need a part cooler, you don't need this modified X carriage. E3D_TA_Mount E3D_TA_Mount_IR I will be using Mini Differential IR sensor (https://miscsolutions.wordpress.com/mini-height-sensor-board/) as Z-probe. E3D_TA_Mount_IR includes mounting holes for this. Version 1.1 (E3D_TA_Mount_IR_1.1) adds cable support and removes X max optical end stop. E3D_TA_Fan_Duct_Mount Uses two more threaded inserts to mount fan duct. E3D_TA_Fan_Duct I printed this in three parts then superglued them together. For now I have omitted the top fan screw because it can contact back of frame. Indicator mount --- https://www.youtube.com/watch?v=DO9Y43uxi5g The mount and clamp work with 8mm diameter stem as found on Banggood digital indicator shown in pictures. Indicator_Mount_1.1 adds support for back of indicator to stop it moving when pressing zero button. Might only fit this model of indicator. Indicator_Mount_Y is for checking motion in Y direction (against front frame). X_Indicator_Stop --- The indicator mount can be rotated 90° (thanks to square hole pattern SCOTT_3D uses for dowel pins) in order to test and calibrate movement in X direction. This end stop mounts (temporarily) on XY_Stepper_Mount; I used M3x12mm screws. As you lose the X end stops when removing extruder mount, G92 X10 can be used once X carriage is jogged into start position, hopefully preventing crashes. Step-down module mount -- For mounting e_goto 24 to 12V converters from SCOTT_3D's BOM (https://www.aliexpress.com/item/DC-DC-24V-18V-to-12V-3A-Step-Down-Module-MINI-Buck-Converter-Power-Supply-Circuit/32778770850.html?spm=2114.13010608.0.0.G2tjiK or https://www.aliexpress.com/item/DC-DC-Step-Down-Power-Supply-Buck-Converter-3A-12V/32812313333.html). 28mm hole spacing for M4 screws. (Inspired by https://www.thingiverse.com/thing:875468). Spool_Holder_Clamp_Top/Bottom -- I'm using this with a length of M8 threaded rod and these https://www.thingiverse.com/thing:2532403 spool holders. Tension_O_Matic -- The screws on X carriage are good for fine-tuning belt tension, as well as squaring the X/Y axes, but this tool should help with overall tension. Currently for 8mm X-shafts, 45mm X-shaft spacing and 11mm belt spacing. 10mm shaft version (untried, untested) here https://www.dropbox.com/s/xpcaoxigcuwk47n/Tension_O_Matic_10mm_1.1.zip?dl=0.
