双Satsana Direct Titan打印头适用于Ender 5

Installation of my Dual Satsana is more complicated that orginal Satsana, so it's
step-by-step instruction:

At first remove everything from carriage... yes everything, Hotend too.

Now you can put bushings between the wheels and carriage into extruder plate
(file name: Carriage_Extruder_Plate_Improved), I used soldering station to blend in this metal parts into model. Its the best way. If you don't have soldering station, you can enlarge holes using 8mm drill and stick bushings into them with hammer.

Make sure that bushings slightly protrude from the plate from the flat rear site.

Connect extruder and stepper motor to model from file "Extruder_Mount_Improved".

I used LDO motor whith is lighter and smaller than defaut in Ender and has 0.9° per rotatinon, instead standard 1.8°, so has twice larger resolution. Conected with Titan, that have triple gear ratio, extruder resolution is six times bigger.

LDO stepper motor: https://www.amazon.de/-/en/Nema-Power-Pancake-Motor-LDO-42STH25-1404MAC/dp/B07ZHLK73B

Remember! Installing Titan extruder or better motor you have to recalibrate extruder resolution in printer EEPROM. It's not a tutorial about extruder calibration, but remember, calibration is necessary!
I reccomend do this before instaling extruder and motor to carriage.

Install Extruder Plate and after that hotend.

And next, you can mount Satsana (file name: Dual_Satsana_Body_V2.1 or REVOLV_Body if you use Revolv version) on carriage.

Fan ducts must be little higher than nozzel. Overall heigh can be adjusted to different nozzels hight, like in orgilanl Satsana.

If you mount extruder and stepper motor only on two screws screwed into the back of the extruder plate, its will bend down forward. Against that I recommend add small plastic plate behind Satsana and motor:

In my case 1mm thickness is good, but this thickness is strongly connected with nozzel hight, the higher nozzle, thinner plate must be installed. Personally, I used piece of PCV, but you can download file "Plate", default thickness of this is 1mm, but as I said, you must adjust it.

In older version there are two holes to mount extruder supprot, in current version only one, because the second screw was blocked by Satsana geometry. On the pictures can you see old version, but installation is the same, just without one screw.

Put schort bowden into hotend, 90-95mm, not more.

Almost over! Now you can put second site of bowden into extruder, screw extruder to the extruder plate with two M3x6 (I used this from default ender extruder) or M3x8 screws, and with single M4x8 to the Satsana body.

And remember, if thickness of plate behind stepper motor and Satsana is less than 1,5mm, you should use pad under screw.

And finally, install 5015 fans using four M4x20 screws.

For cable of left 5015 I designed special trough behind the hotend.

5015 fans must be connected in parallel, Plus to Plus, Minus to Minus, Red to Red, Black to Black. Default Ender fan was conected with blue and yellow cable, blue is Minus, Yellow is Plus. So, Red to Yellow, Black to Blue.

Very important when installing Titan Extruder is to reverse stepper motor plug, or resolder the wires. Titan have triple gear ratio whith works like a reverse, so you must turn around direction of rotation of the stepper motor.

Dual Satsana with Direct Titan Extruder is mounted, now just level your bed and print something.

Version I:
First version, included in Old_Version.zip folder.

Version II (23.06.2023):

Added "Plate" Model.
Models with "Improved" and "V2.1" postscript:

Satsana_Dual_Body_V2.1:
-Geometry improves;
-One screw behind stepper motor and Satsana;
-Now Satsana_Dual_Body_V2.1 can be printed without supports.

Carriage_Extruder_Plate_Improved:
-Geometry improves;
-Bigger bushings holes.

Extruder_Mount_Improved:
-Geometry improves.

Version III (24.06.2023):

Added "Plate" to .blend file.
Models with "V2.2" postscript:

Carriage_Extruder_Plate_2.2:
-Geometry improves.

Version IV Revolv (14.10.2023):

Added Revolv logo to .blend file.

Dual_Satsana_Body:
Model was replaced by REVOLV_Body STL file.

Rest of models are the same as in 2.2 version!

If you would like remix this remix (yes, I know it's funny) I included Blender files in .zip folder.
By the way, in .bledn files in "Not-printable Objects" I used this models:

Thanks for authors, this models was very helpful!

In the near future I'm going to print same test models and compare results with standard Satsana, so soon I will publish comparison photos.

On my Thingiverse profile I created Collection "Dual Satsana" where I will add accessories to Dual Satsana. In my nearest plans is mount for dial indicator and BL-Touch.
