material feeder beeping like crazy

Recommended Posts

no need to mess with the screw, put it back to how it was, and just do atomic pulls properly and print off the roll and your problem will vanish.

atomic pulls:

 

printing off the roll:

 

your prints may look fine for a while if you dont do atomic pulls, but its only a matter of time before your prints suffer from a blocked nozzle or snagged filament. works for me everytime. Beeping is retraction that is something unrelated and it does that when its moving from one part to the other. sort out the annoying clicking first with atomic pulls and go from there.

You want enough tension on the filament that you can see bite marks on it.

Next, if you are getting kick-back, you might have a clogged nozzle as @cloakfiend suggests, or the temperature of your material is too low, or your printing speed too fast. There is no set speed for PLA or any other material; each roll can and usually will be different and therefore you have to learn the extrusion volume/temperature/speed ratios all over again for every new roll you get.

You may be simply printing too fast or too cold.

Here are top recommended speeds for .2mm layers (twice as fast for .1mm layers):

20mm/sec at 200C

30mm/sec at 210C

40mm/sec at 225C

50mm/sec at 240C

The printer can do double these speeds but with huge difficulty and usually with a loss in part quality due to underextrusion. Different colors print best at quite different temperatures and due to imperfect temp sensors, some printers print 10C cool so use these values as an initial starting guideline and if you are still underextruding try raising the temp. But don't go over 240C with PLA.

    • "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.
