Tevo Tarantula Dual Inverted Z Motor Mounts with Oldham Couplers and screw adjustable limit swich

thingiverse

This is dual inverted Z setup for Tevo Tarantula printer. I designed this because other similar setups did not worked for me (no clearance for Z limit switch and other problems). This setup it well tested and working with stock Tevo Tarantula printer and also with Mackers.it carbon fiber upgrade. It also includes Oldham couplers (check it here: https://youtu.be/5uvDgNP4m2o) to get rid of any Z wobble caused by thread rods not being straight and new adjustable mechanism for setting Z limit switch distance using screw. Did you find this thing useful? I spent huge amount of time designing and finetuning this - it would be nice if you consider supporting me via my patreon page so I can create more useful things in future! https://www.patreon.com/tomfrajer Thank you! Print Settings Printer: Tevo Tarantula Supports: Yes Resolution: 0.3 Infill: 30% Full Honeycomb Notes: You will need to use supports for Right motor mount and Limit switch bracket. Default setting for supports in Simplify3D will do well. Also do not forget to rotate all parts so they will lay flat side on bed and you will have minimum overhangs that need support. 1, Print Left_motor_bracket.stl and Right_Motor_Bracket.stl 2, If you want to use screw adjustable limit switch feature, print Limit_Switch_Mount.stl and Limit_Switch_Screw_Holder.stl 3, If you want to use oldham coupler, print 2x Oldham_Coupler_Bottom.stl, 2x Oldham_Coupler_Middle.stl and 2x Oldham_Coupler_Top.stl. If you do not need/want couplers, print 2x Leadscrew_Nut_Bracket.stl instead Post-Printing Glue on limit switch block Depending on what fit you will have - in case of limit switch mounting block is not tight fit, simply glue it in place! Invert Z axis You need to invert Z axis movement direction in firmware. Open firmware source in Arduino, connect printer to computer via USB, edit this line in Config.h and upload your changes: define INVERT_Z_DIR true
