Ok, there is a problem, unless I assembled wrong. The way the assembly sits in the carriage now, only one bolt goes through the carriage. The bottom left is secured through the carriage and motor but the bottom right does not. Because of this it shifts. I am going back to review my assembly.

This only seems to apply if you had already drilled out for the e3d, did I print out the wrong mount?

You have certainly done something wrong. I have three going Init the stepper, top-left, top-right, bottom-left. The Bottom right is the short bolt. Only goes into the captive nut within the Titan body.

Correct, but only one goes through the carriage. With the shim I printed there is a 3mm gap which allows the assemble to shift.

For those of you asking about Titan, as well as Titan with a small short stack (pancake) stepper motor:

Ok after some working out here is the fix.
If you have done the E3D v6 mod previously and don't wish too drill anymore holes.
I have attached a new bracket called No More Hole. Print this and the excess gap you have will be filled in, this will prevent the carriage/stepper movement.

Hope this helps, sorry for any confusion

ok, next problem, we need to drill, if not, the extruder nozzle is too high and the back of the carriage will catch on the right rear screw of the heated bed and make a awful nose.

Just so I am clear, you had previously done the e3dv6 mod and the first bracket, allows for "wiggle room" and the second one makes hot end too high?  So the solution is to use the first one with new holes?

E3d mod...yes
Wiggle room....yes, about 3mm. So I made a shim to stabilize it then when I went to print after leveling the bed the back of the carriage caught on the screw. I don't see another way other than to drill new holes. But even when I did the e3d mod it would bump that screw but never hang.

I have seen others remove the screw and use plastic zip ties instead.  Not ideal but it may work.

I guess I am trying to figure this out in my head.  It has been a bit since I did my E3d v6 mod and I thought the guide here was using the original mod as a starting point of sorts.  Drilling a few new holes is not too big of an issue assuming they don't overlap with other holes.

I assumed you used the new moded bracket posted?

Perhaps give the zip a try.  At the least you may be able to print out the new bracket ssauntson made.  Hopefully I get a chance to play with this next weekend.  For now I am looking at the original stepper but looking at the lighter version you have.

II am so sorry this is causing so much hassle. I personally didn't have any of these issues.
Seriously, I just did the mod, set it up and printed. As I said in the guide. I did do the carriage drop by 2mm, I think this may have been fortunate as my nozzle as never touched the rear screw.

If it helps, I'll make an adjustment to the bracket to fill the first holes drilled and leave the new holes only. This may stabilise everything by locking the two parts together. PLEASE let me know if this is of interest as it'll take some time to accurately draw this, taking into account shrinkage.

I am truly Sorry to the community.....

P.S would it help too add some Start Gcode to move the bed down by say 5mm before moving the carriage and then Reset the Z axis?

My Start Gcode

Start -
M140 S[first_layer_bed_temperature] ; Bed (no wait)
M106 S255 ; Start fan
G90 ; set absolute coordinates
G28 ; home all axis
M190 S[first_layer_bed_temperature] ; Bed (wait)
M104 S[first_layer_temperature] ; Extruder (no wait)
M109 S[first_layer_temperature] ; Extruder (wait)
M117 Start
M117 Cleaning
M100 ; Cleaning
G1 Z5 F1500
G1 X0 Y15 F1000
G1 X32 Y30 F1000
G92 E0 ; reset extrusion distance
G1 Z0.3 F4800.00
M117 Printing

Set Temps as required. The line which will prevent hitting the screw is G1 Z5 F1500 before G92 E0 which then moves it back. This tells the bed too lower by 5mm before moving
