Tevo Tarantula Pro Z Axis Linear Rail upgrade

thingiverse

This upgrade is designed for the Tevo Tarantula Pro, stiffening its Z-axis and reducing deflection caused by a bent leadscrew. It was created to print quickly without necessitating a complete redesign of the TTP. This upgrade is compatible with MGN9H Carriage blocks on a 9mm Rail. You can purchase these on Amazon at https://www.amazon.com/ReliaBot-Linear-Carriage-Printer-Machine/dp/B07ZJNML2Y/ref=sr_1_1_sspa?dchild=1&keywords=MGN9H&qid=1584725712&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzNkI2SkNPTU5EUDNYJmVuY3J5cHRlZElkPUEwNjQ5NjA2MlFaQ1NTS0s0SkpTQSZlbmNyeXB0ZWRBZElkPUEwMzExMDU1MTFLRldGNVFKRko0WiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= It is recommended to have at least two carriage blocks on the motor side. With only one carriage block on each side, the X-axis could be unstable when printed with PLA material. Machining from aluminum would make for a stiff attachment. The printed carriage mounts are interchangeable so if you only want one on each side, that is possible. Screw your M5 screws tightly with nylon lock nuts. The Z-axis motor mount is necessary to account for the extra 14mm added by the leadscrew. This is also a great fix for the TTP's terrible issue with leadscrew alignment. I recommend printing this face down without supports. Once printed, hook everything up, drop a leadscrew into the flange and line the motor up. Then, just tighten down the two screws. The Alignment Jig is designed to center your rail as you screw it down so that you can easily and accurately install the rails without issue. I tested this for several days through several prints to ensure that this was indeed an upgrade and doesn't cause new issues. I hope this solves an issue you're facing on your printer, and I hope its easy enough to install! Happy printing. This modification requires adjusting the green 2020 extrusion plates. They will need to be moved outward in order to account for the extra width. This process is easy and reversible.
