Dual Titan Aero? Heck yeah!
This is a bracket to hold dual Titan Aero heads side by side. It's re-worked for the CR-10S mounting bracket, but loosely based on the design here:
The latest (final) update from September 1 includes a block that pushes against the X-axis switch. Also, the heads are moved forward slightly to clear the side bar. This has been installed and tested to be 100% working! :) The supports look like a mess, but I kept adding them until I felt comfortable with the lack of flex. This is super sturdy.
In Marlin or your slicer, you'll need to set offsets to the heads. Here's the closest I have come to the offset distance. Assuming head 1 (on the left) is at 0,0 -- you'll want to set the head on the right to an offset of X +36.36, y -5.85
The BLTouch bracket is approximately offset 17 to the right and 20 behind (x +17, y +20)
The BLTouch distance from bed that worked for me is z -1.9
FYI, Creality boards don’t have the second extruder stepper driver. They have a spot for the second extruder to plug in but to my knowledge, the only place to get a working dual extruder board is from TH3D.
Stuff you'll need:
Creality CR-10S board with the additional E2 stepper driver
Titan Aero (one standard, one mirrored)
Colorm3d from Amazon PETG
Minnesota Purple Translucent
I printed this upright (front facing front, top facing top). It was a bit tricky removing the supports without breaking off the zip tie hook on the back -- in fact, I broke mine while weeding the supports off.
It took 10-12 hours on an Ender with 247c head and 65c bed printing PETG.
As of September 4 (referring to the September 1, 2019 STL update), I'm removing the "work in progress" flag as this is being used in production with great fit and great success.
