Topic: Ninja flex success!

I purchased some fire red Ninja flex, just had to try my hand at printing this stuff.

It's like wet spaghetti to feed but my Bowden setup handled it with ease.

Printed off 3 items including the iphone case and they turned out great.

Hotend temp was 238c and bed 20c or cold worked best.
I used S3D to slice and slowed the print speed down to 20mm per Ninja flex recommendation.
All other settings were what I use for ABS.

Like to know what settings others use for Ninja flex to get the best print?

Re: Ninja flex success!

Are you using an e3d?  If so, can you direct me to which carriage you used?

Nothing to fancy here.

I'm using the Bowden E3D V6, great hotend, prints anything you can feed it.

It's mounted on the stock carriage for now but have not seen any
reason to change it as its small and light.

Got the extruder drive MK7 off of Thingverse that was designed for flexible filament.

AWESOME!!!

Do you recommend this for the E3D? http://www.thingiverse.com/thing:709228

That part looks like an entire carriage.

This is the Bowden extruder drive I used.

Remember the Bowden setup moves the stepper motor off of the carriage and feeds the hot end
by a silicon tube thus removing all of that weight allowing faster more crisp head movement..

I was Leary of that kind of setup at first but now realize it is a better way to go in OMHO.

Get used to it, it's the Delta way!

Constructive criticism always welcome. lol

Re: Ninja flex success!

No criticism just a note, Bowden setup does NOT use silicone tubing to feed the filament it uses PTFE tubing.  Just don't want any confusion.

Printit Industries Model 8.10 fully enclosed CoreXY, Chamber heat
3-SD3's & a Workbench all fully enclosed, RH-Slic3r Win7pro, E3D V6, Volcano & Cyclops Hot End

I stand corrected.

I'm still new to this 3D so I probably use incorrect terms.

I'm still not sure if the extruder and hot end are the same or if the extruder is the drive motor and where is the cold end at. LOL

Re: Ninja flex success!

No worries wink
The extruder usually refers to the motor and the hot end is the assembly below the motor.  There are different types of hot end but all of them have similar components.  The top section is the cold section then inside there is some form of heatbreak then the heatbblock and nozzle make up the hotend of the whole assembly.  Ironically the whole assembly is commonly refered to as the hot end.
So don't feel bad if you don't get all the terminology correct.  I just didn't want a new thread from someone asking why their Bowden setup wasn't working.  That would take pages of troubleshooting before we discovered they had used silicone instead of PTFE.

Re: Ninja flex success!

How did you feed material. Did you spool an xyz cartridge or spool it off of the Ninja Flex reel? How long did the case take to print?

Thx

Thanks for the explanation.
I know that reading through the threads someone says they changed the extruder when in fact they changed the hot end or vise versa.
It gets confusing at times.
So the stock Da Vinci is not a Bowden setup, is it considered a direct drive setup?

I have Repetier on my printer and I fed the filament off the Ninja flex reel that is mounted on the outside of the cabinet.

The iPhone case took just under 2 hours.

I just printed a motor vibration gasket and it took 12 minutes.

Re: Ninja flex success!

Can this work with xyzware firmware and S3D? I don't want to mess with Repetier. I currently have a Davinci 1.0A with stock firmware v. 1.0.1

Thanks

Thanks, I do also think that it is better for the Extruder (motor) to be off the XY rail assembly, thus removing weight.

Stock firmware and S3D should work ok, the problem you would run into is the stock extruder and hot end, I don't think they will work with flexible filament.
