need some help

Recommended Posts

I have received my ulitmaker 2 yesterday and printed some things

as of this morning I am getting weird issues. see image below

ScreenHunter 497 Mar. 26 13.17

 

this is the robot from the flashcard, it behaves weird after a while.

I have also reprinted the ring and that one is looking like a swiss cheese

 

any idea what is going on ?? I suspect the extruder or extruder speed ,

That is basic underextrusion. A common problem. Usually it means you are printing too fast or too cold. Here is a suggested max print speed for a given temperature assuming .2mm layers. You can print twice as fast for .1mm layers. It may be that you have to shove the filament in hard when you start printing again to get it past the current spot as you probably ground down your filament right at the feeder:

ASSUMING .2MM LAYERS

20mm/sec at 200C

30mm/sec at 210C

40mm/sec at 225C

50mm/sec at 240C

the diamond pattern on the PLA looks fine, I am not sure what caused it to under extrude, I retracted the PLA and re-inserted it, tighten the feeder up a little bit and it seems to work with the standard settings on the flash card. I will talke note of your recommended settings for my own models.

thanks for your help

    • "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.
