I have been working for a while on a direct drive mount for the Chimera/Cyclops using titan extruders. Due to the size of the Titans the best I could do was to do an elongated direct drive. The stepper motors I used are great because you can plug them directly into the existing cables. I am not 100% sure if they are compatible so if someone could double check for me that would be great! They can be found here: http://www.omc-stepperonline.com/nema-17-bipolar-step-motor-29v-07a-18ncm255ozin-17hs100704s-p-260.html
In addition, I am using the BLTouch probe. I am also hoping to find a good method to mount cooling fans if anyone has some input. I am currently printing out a stiffened mount as well.
