Flexible filaments

Ok great. ill have to look into that cleaning filament.

New topic, Id been having fairly loud fan noise, so I replaced the fan thats attached to the bottom panel when you open up the printer. Its the only thing attached to the bottom panel. Apparently that isn't the one making the noise. I already tested the two on the extruder assembly by unplugging them both and the fan noise still persisted. Im not sure if its off balance or what, but Its quite loud and it didn't do it for the first month that I had the printer. So the only other fan that is left is in the power supply right? so now what?

 

Yup the power supply fan.

You can buy a 60x10mm fan and try and replace it if you want.

 

You say TRY and replace it... Is it supposed to be hard? lol Ive never replaced a power supply fan.

I started printing NinjaFlex yesterday. Ive yet to have a 100% successful print... The first 3 prints I tried were the best, and it went downhill from there... The first 3 got about 1/2 to 3/4 complete before they messed up. Now, I can't get past the base layer before it screws up. The recurring problem seems to have to do with feeding the filament. I have a tube with the hole in it which 'appears' to feed well until the brim layer nears completion, then usually the filament just stops feeding, like its losing grip. In the image below you can see the inner circle layer is nice and the outer circle is all choppy...

 

Im running at 25mm/s now, I've tried 20mm/s and it didn't change anything. The first 3 prints that came out better were at 30+.

 

Correct

 

It's just like replacing any other fan. There's a connector plug the the fan plugs into on the PSU circuit board and then a couple screws holding it to the enclosure.

you can kinda see the plug in this picture:

 

Ok thanks.

Im wondering if the issue printing NinjaFlex could possibly have anything to do with trying to print a Brim layer? every time I've tried to do it with brim its messed up, I just started another one without it and it "seems" to be doing ok again. Even so, I've yet to have a completed print when I did it without brim, part of the problem is that halfway though it would become unstuck from the bed.

 

Ive yet to have a successful print, it ALWAYS loses it around the halfway mark, and starts leaving those "droplets". I just don't get it because half prints great.

 

My print is only about 1" round like a rubber tube basically... I can't get 1/2" high before it starts spitting out droplets instead of a steady stream and I can't figure out why 1/2" is the magic height...Ive printed about 8-10 and its almost always the exact same spot every time. My first two tries got about 3/4" high, but after those I never got that high again.

I remember a while back when I was using matter control, someone told me to change my steps to 2560 if i had M8 rods. Could that be an issue? I changed it in MC but I didn't see a spot to adjust it in Cura. Should the steps/mm be different for NinjaFlex?

 

Not to be rude, but does anyone have a picture of their working setup where they have a ruler that they can show the actual size of the tube and where the hole is?

I managed to find a bic style pen and cleaned out the ink tube, it's a perfect fit and I want to make sure I don't screw it up.

 

I don't know what you mean by that and have no idea how to find that out.

 

That's the post I quoted in my first question. I was asking specifically because I can't judge the size based on your fingers. I have no idea how big your hands are.
