Tevo Tornado Direct Driver Extruder Mounting Plate

thingiverse

This is a mounting plate used to convert my Tevo Tornado retrofitted with an aftermarket aluminum extruder to a direct drive feed, which was installed in order to print rubber-like TPU filament. Basically, this bracket, it's a reworked version of a CR-10 Direct Drive mounting plate made by s_gutz. Modifications are as follows: Mounting plate is rotated 90 degrees counterclockwise to prevent interference with frame. Mounting plate is shortened at the bottom to allow better hotend cooling. Mounting plate is shortened on the left hand side to maintain identical limit switch positioning. Holes are added to top section of bracket for tie-wrap cable mounting. Note that the aftermarket extruder that I have installed is compatible or created for the CR-10. https://i.ebayimg.com/images/g/jTIAAOSwVkBeOQVr/s-l1600.jpg. For changing to this extruder, it is necessary to roll two of the four extruder wires, as well as recalibrate the extruder gain from the Tevo control to account for the different gearing. Some people have ordered a thinner and lighter motor, but I just used the Tevo OEM unit. Also note that the X-axis limit switch will need to be shimmed forward the same thickness as the plate. Instead of the printed plate that s_gutz designed, I ended up using a small stack of small washers. As I recall, you will need longer M3 screws for the limit switch, and I used the old limit switch screws to mount the hotend (my hotend is a Chinese knockoff of a Swiss style unit, which employs the same mounting holes/system as did the OEM hotend. Finally, please note I also did install a longer cable set for the hotend and feeder motor. I don't know if the shorter OEM cables would work or not. Overall I like the modification and have been getting good TPU prints. The only thing that I don't like about it is that the screws to hold the hotend are now also holding the entire extruder feed. It seems rigid enough but when you need to do maintenance to remove the hotend you need to off the entire feeder assembly as well. Special thanks to David at the Cedarburg Library for printing this out when my Tevo was in pieces!
