Titan Aero - X Carriage - Anycubic 4Max

youmagine

This is a custom-designed titan aero x-carriage replacement intended to replace the standard Makerbot style carriage on my Anycubic 4Max. It should, however, fit on any Makerbot-style x-carriage with a rod distance of 70mm. The primary concept involves positioning the Titan Aero beneath the carriage and sacrificing some printing height (approximately 70 to 75mm) for a more rigid and titan-ic setup. This new design also significantly simplifies calibration and allows for real-time observation of the first layer before the print is complete. For bearings, I will utilize two LM8LUU units (size) as used in the original 4Max carriage. These can be replaced with copper bushings in the same size for added durability. Initially, I encountered some difficulty pressing in the LM8LUU bearings, but this was largely due to my machine's calibration being off. The bearings fit snugly without clips but may exert some stress on the plastic. Following recalibration and a thorough test of the printer, I will revisit certain aspects of the design to address this issue. For optimal performance, copper bushings can be sourced from here: https://www.aliexpress.com/item/8x15x45-mm-linear-graphite-copper-set-bearing-copper-bushing-oil-self-lubricating-bearing-JDB-for-shaft/32847632821.html. To enhance the Aero's functionality, I will attach a BL-Touch to its right side using this mounting bracket: https://www.aliexpress.com/item/SWMAKER-1pcs-Titan-Aero-BLTouch-Mount-Titan-Aero-Extruder-Prusa-i3-MK2-BLtouch-Mounting-bracket-Aluminum/32888473302.html. For part-cooling, a 30mm fan will be mounted to the left side of the Aero. Although I am uncertain if this fan is sufficient for PLA, it should suffice for other materials such as PETG, ABS, and Flexibles. If you've had any experience with this setup, please share your findings. The belt-lock design was inspired by @VVilhelnn's creation: https://www.thingiverse.com/thing:1533955 Required components include: - 30mm fan - Titan Aero - Possibly longer M3 screws for mounting the Aero (mine came with two sets - short and long) - Firmware modifications: + Travel limits (mm) after homing, corresponding to endstop positions. define X_MIN_POS -8 //before was -5 define Z_MAX_POS 240 //before was 300 Plus: Changes needed for operating the Titan Aero, dependent on your stepper motor. Future plans include redesigning the y-carriage to regain some lost height.
