Belt driven dual Z axis Tevo tarantula by Kselleslaghs

Last crawled date: 3 years, 1 month ago

UPDATE: 3/09/2018
I added frame mounts with integrated beltpulleys, you can mount these if you want the belt upgrade + frame mount. it is easier to print, you have more z clearance...and your printer is more accurate because of less frame vibrations!
these are the new files :
-right frame mount+pulley
-left frame mount+pulley
Old files where deleted, this setup is tested.
This is a remix of the Belt driven Z-Axis / Worm Gear Mount" by VecteR.
This thing allows for belt driven z axis on the tevo tarantula.
i`ve made some changes so you can implement belts on both sides of the Z axis to maintain the stability of the z axis (driven by just one stepper motor).
To install correctly i attached some photos, but please check for the detailed installation of some stls the original thingi here : https://www.thingiverse.com/thing:1966483
No need to change firmware or calculate steps/mm because worm gear maintains same ratio as standard z rod....
When powering down the stepper motor, the worm gear prevent the x gantry to fall down.
Many thanks to VecteR!
