So it has been a while. I have detailed so many hardware modifications to my Black Widow printer but I have not kept up on the software end. If you guys can believe I have been running marlin 1.1.0 on all 3 of my machines. Also I have been running an older version of Arduino and I even had old firmware in my MKS TFT touchscreens. As much as I always liked the alternate firmware I had loaded in these screens it was an older firmware. So I have been setting up 3 copies of marlin 1.1.9 for each of my printers and I have updated the firmware in the TFT touchscreens with a win8 theme and I turned up the speeds a bit. Here is a short video of my Black Widow's new print speed:

To make this all look like it belongs I chased down the right parts. I got a black genuine E3D titan aero stepper motor, a black drive pulley, and black m3 x 7mm screws..



The way I hooked this up required no changes to marlin. There is a header next to each stepper driver socket that is a breakout for the Arduino pins that drive that socket. I connected this expansion board to the appropriate pins on the header next to the driver for the Y axis. And this whole mod is plug 'n play. Here is someone else's instructional video on making these connections:

And here is my completed 2 motor Y axis..
