Belt driven dual Z axis Tevo tarantula

thingiverse

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 photo`s, but please check for the detailed installation of some stl`s 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!
