The Redrex Titan-style extruder listing, bullet by bullet

Five bullets: an optimised filament guide that stops flexible filament bending, kinking or jamming in the feed; injection-moulded plastic parts for a Bowden setup, compatible with V5, V6 and J-head hotends; a note that the stepper motor pictured is not included; an E-steps value of about 418.5; and a link to a video tutorial.

The motor missing from the Redrex box

Pictured, not supplied. The third bullet is explicit: the stepper motor shown on the listing is there for illustration. The product photograph used on this page shows the kit in parts, with a motor bracket and no motor. A motor has to come from elsewhere.

Redrex and flexible filament

The first bullet is about flexible filaments: an optimised guide meant to stop them bending, kinking or jamming in the feed. The E-steps figure of about 418.5 sits alongside it.
