Tornado CR-10 Frame Brace Dual Z

Last crawled date: 4 years, 2 months ago

This is a full frame brace, & dual Z mod for Tevo Tornado, CR-10, and other variants. A few extra parts are needed : 2- leadscrew/shaft collar clamps, 2- 8mmx10mmx1mm washers for between the bearings and pulleys, 1- Smooth idler bearing for the belt tensioner(I used openbuilds), 8- M8 nuts & 4- 600mm M8 threaded rods(trim to fit, 5/16" also works fine), various M3, M4, & M5 screws/nuts & t-nuts, 5- 625-2RS bearings, 2- 600mm T8 2mm pitch 8mm lead leadscrews(trim to fit) I'm probably forgetting something else :)
This setup is a mashup of a few different mods edited to suit my needs. This is a VERY solid setup. a little tip : Take your time to line up the leadscrews and motor mount,and the Z axis wheels. These must be in PERFECT alignment & tension to stop Z banding/ringing. Also be sure to use the proper aluminum wheel spacers for the Gantry plates to keep proper alignment. This was based off a Creality printer first, so uses 8mm spacers(Original Tornado uses 7mm).
The "Frame_support" & "Frame_support_short" files are to stop the bottom frame from flexing between to rubber feet. The "short" file allows a 3mm thick piece of silicone sheet or 3mm printed TPU gasket to be installed between your table and the frame_support. This will help to stop external vibrations being transferred to the printer.
The "tie_rod" files have a bigger hole and smaller hole. The small hole version allows the threaded rods to thread into the tie rod. The big hole version allows the threaded rod to "slide" inside the tie rod, allowing tension adjustement of the frame brace. Use 1 of each type for each threaded rod. SuperGlue or Epoxy the M8 nuts into the BallNutM8 pieces.
I use adjustable Z endstop for easy nozzle changes and nozzle height adjustments, so I included those files also. Epoxy the X_End_Stop_Nut into the X_End_Stop_Support. I'm not sure why the original designer left these pieces seperate, but Epoxy does the trick :)
Only 2 of these parts need to be printed with supports, Z_endstop_support_V2, and bearing_mount_625x2. Just be sure to put the proper face against the bed(sorry I'm too lazy to reorient the models :P)
