Sadly, but due to the lack of interest for EVA / Titan I will be deprecating it. Titan served us well, especially in the early days as an alternative for the lousy extruders printers came with.
Deprectaion means that this is the last release this variant got an update, next time it will be marked as obsolete. This means that it will stop receiving upgrades but will forever be available in the 2.4.0 version in it's submodule repository.
EVA / Titan is the oldest and
in my opinion one of the best variants the one quite closest to my heart as it was the original and only extruder option for the first Easy-Mod - later was moved to a separate project which EVA become
Since EVA 2.0.0 it does not require a unique
front part, just a
top (like BMG) which makes it not only easier to assemble but also to maintain. One can opt to use the
press fit part if is lacking a groove mount adapter.
There is a PTFE tube going from the Titan to the hotend so it's not as "direct" as one could imagine but still the print quality is excellent (or at least not impeded by the carriage).

Custom Titan Tension Arm
The BOM contains my remix of the E3D Titan Flex Upgrade thing which improves the Titan filament path greatly.
My remix improves it's printability - print on the side where the spring is. No supports are needed.
You can ommit the
SSX_tensioner_thing_2426505 part from the BOM if you plan on using the original arm.
Universal EVA Front
This drive uses the universal face, which means it's compatible with all hotends you can find in the Hotends section.
Bill of materials¶
PTFE Tube lengths
I have split the lengths into two, the drive side and the hotend side. You need to sum the two lenghts from this and the hotend BOM you'd be using. (preferrably get more PTFE)
Do not cut the PTFE into two pieces

STEP files? CAD Link?
If you are looking for the CAD link to tamper with the design or to export the parts in formats other than STL you can find the links bellow.
Be warned though! The link directs to a live - bleeding edge - version of this particular EVA module - there is no promise it will be the same version as what you see above nor does it have to be the version Rat Rig provides.
