Tarantula - Z MGN9 Rails Mod

thingiverse

After creating a dual Y rails kit for my Tarantula, I was impressed by how it effectively eliminated all plays caused by the wheels system. I decided to take it up a notch and put together this Z rails kit by remixing parts from other creators. The Vertical Belt Tensioner (by pin13) and the X motor mount from Ultimate TEVO TARANTULA upgrade (by kwijatkowski) were modified to work with MGN9 rails (MGN9H rail block). Great thanks to these creative minds! This kit will move both Z lead screws to the front and offset the extruder around 10mm on the Y axis. Minimal modifications are needed for the X axis, mainly bolting down the MGN9 rail with a few M3 screws. (Update: 6/28/18) The X-Carriage is now available for download at https://www.thingiverse.com/thing:2980917, featuring quick change options for laser and other applications. Here are the specs: * 2 x 350mm MGN9 Rail with MGN9H block I source these rails from Aliexpress.com for about $11 each, but shipping can be slow. If you're planning to upgrade your X-axis rail, I recommend going with the MGN9 - it's overkill to use the MGN12. Print settings: * 0.2 Layer Height * Min 40% Infill * Support enabled * No Raft Get ready for RAIL FEVER! Pair this kit with my Tarantula Dual Y Rails for the ultimate spider experience! https://www.thingiverse.com/thing:2945233 MGN9 X-Carriage - Quick Change (Chimera and 33mm Laser adapters) https://www.thingiverse.com/thing:2980917 MGN9 X-Carriage - Quick Change (E3DV6 Bowden J-head adapter) https://www.thingiverse.com/thing:2987715 UPDATE: 10/4/18 - This mod now includes Z lead screw gantry - Added a link to my quick-change E3DV6 Bowden extruder and updated photo
