Tevo Tornado Under Bed Standalone Kit
Description
Standalone kit for Tevo Tornado This kit allows mounting of the components from the Tevo Tornado control box and Raspberry Pi 3B+ or Pi4 under the bed and the screen on the front rail. It utilises two 6015 fans blowing downward directly onto the stepper drivers for cooling. The air is then directed out the side of the case and also through the PSU case for some cooling there. Although the X and E stepper plus X-limit cables are on the short side and could be lengthened, no cables HAVE to be lengthened for this kit to be fitted. The case lids are designed to be a snap on fit. The design is optimised for printing at .2mm layer height and should not require supports. The mains socket from the control box needs one of its mounting ears trimmed off to allow it to fit under the frame rail; see photo. I printed the frame feet in a firm flex filament so that they are not totally rigid. You could print in a rigid filament and mount the original rubber feet to the bottom if you wanted to. If you do this the small feet for under the cases will need to be stretched in the Z dimension so that they still contact the surface your printer sits on and support the cases. There are several versions of the mother board case covering MKS Base 1.4(first Gen Tornados came with this board), MKS Gen-L 1.0 (subsequent Tornados came with this board), MKS SGen-L 1.0 and MKS Gen 1.4 with separate versions of each for the Pi3B+ and Pi4. Please note that I have only tested the Gen-L version, if you encounter any errors with any versions please contact me with details so that I can revise the parts. There are two versions of the PSU case, one with tabs for mounting under the centre (Y) extrusion and one without. This is because different people have asked for it both ways. There are also two versions of the screen case: 1 One that mounts the screen at 45 degrees from horizontal. This will protrude below the surface that the printer sits on. If the front of your printer sits out past this surface it will work. Otherwise to use if you will need taller feet which I have not designed. 2 The second has a screen angle of 24 degrees from horizontal but does not extend below the surface your printer sits on. In both cases the screen case needs to be mounted to the frame before installing the screen. I suggest test fitting the screen and tapping the holes with the M3 cap screws before mounting, then removing the screen, mounting the case and reinstalling the screen. Please note that it is your responsibility to make sure that your work and the finished product meets any legal and safety requirements in your location. I accept no responsibility for any legal breaches or injury you incur from making, installing or using this kit.
