    Hi all,

    I am thinking about printing flexible filament and have been studying the thread about it. Tried the pen tube mod a bit. But it doesn't look like a very permanent solution. The plastic pen tube doesn't last very long I think.

    Isn't there a better and more permanent solution out there?

    So I can across this Flexion kit:

    https://flexionextruder.com/shop/single/

    Does anyone know whether it can be made to fit Robo3d R1 Plus? What's your opinion on it? No better than pen tube/brass tube mod? Waste of time to be investigating or investing into this kit? The latest Robo3D R2 or C2 can do flexible filament better?

    If I want to swap print between PLA and flexible without too much trouble. Any thought?

    Thanks, CJ

    Hi cj. I use an e3dv6 and a promethius v2 and print both pla and flexibles without much hassle.

    This maybe a very dumb question but I thought it's important to have supported path both before and after the feeding bolt?

    Not a dumb question both hotends use a ptfe tube, i take it all the way above the hobbled bolt and notch out the tibe for the hobbled bolt. This gives me the full supported path

    Another option is to look at installing the Titan extruder from E3D. That does give a PTFE guided path into the extruder and down into the E3D hotend. I've heard folks having great success with the Titan printing all types of filament including the flexibles.

    I can't remember the forum user that just recently made a mount and upgraded to the flexion. He really liked it, but can't remember his name off the top of my head and if he did flexibles on it yet.

    EDIT: @teknoprep was the user I was thinking of.

    Thanks for suggesting Titan Extruder. I like it. I have a stocked R1 Plus that should be able to retrofit with it. I wonder if any one has done it and could provide an instruction. Flexion is nice too but can't hand guide the filament. Going to spend a few days at least to study them...

    I have a Titan Extruder on both of my Robo's.

    Prints flexible well, the only gotcha I found was keep the tension screw about one turn from full loose. When I made it too tight it has trouble.

    I used a simple design I copied from Thomas on youtube...

    And I'm using YOGI's design on my other robo.

    Hi KTMDirtFace,

    with the Titan setup, what is the speed you were able to print with the flexible? And did you turn off retraction?

    Thanks, CJ

    I haven't used it a lot with flexibles, but yes I turned retraction off. and Printed at 30mm/s using NinjaFlex. I think it could print faster, but I haven't tested it. Also I only have ninja flex, which is probably the hardest to print with.. its really flexy

    FYI this was printed at 60mm/s on my Modified Replicator 2 which I no longer own. In ninja flex. no retraction. Also NEVER print ninja flex to buildTak.. lol it wont come off! Actually glue stick helps ninja flex not stick as crazy to the bed. So If you have build tak or some other crazy sticky surface, put glue stick on when doing flexibles so it Does Not stick as bad :)


    I think the robo with titan could do it now...but I have not tried.
