weird retraction on feed wheel

Recommended Posts

I had been printing quite nicely with colourfab filament then changed to another filament . the filament then was not extruding enough and some prints failed . i tried changing the tension on the feed wheel at the back but it didnt help so much . i tryed upping the material flow which seemed to help to some degree , 0.1 prints where easier than 0.06 on the 0.06 prints i upped the material flow to something like 300 % material flow .

i noticed the feed wheel would slip backwards when the prints failed , it looked like a retraction but at a place on the print where there was not a retraction . it seems weird that instead of the material slipping that the wheel actually moved backwatds . does anyone have any advice ??

Ok, next thing to check is the filament itself. Does it still have a diameter of 2.85mm?

Another idea, check the feeder to see if there aren't any bits of broken or ground filament stuck.

the filament is fine and has diameter of 2.9 the feeder also is fine i looked it over .

i maanged to get a print out yesterday but with a much thicker layer hight . it seems it stuggles more the thinner i go . .

It's possible that the hobbed nut itself is loose. There is a grub screw on it which might require tightening.

thanks i will look into that . it is strange though that it prints other filaments fine . thanks for the tip i will take a look . i am also looking at reprinting the feed mechanism there

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
