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 were 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 prevents the x gantry from falling down. Many thanks to VecteR!
