[Possible Underextrusion & How to Fix]

-I forgot to mention I am printing with the Silver Ultimaker PLA that came with the machine. I haven't changed the temperature setting so that should be the default of 210. I will give 225 a try.

-I will also listen and watch for clicking. I haven't noticed anything yet, so I think this is OK.

-If I go to the Advanced Settings, they are still on the defaults so the speed settings are (in mm/s):

Infill speed: 80

Top/Bottom speed: 15

Inner Shell speed: 60

So these should all be set to 0 to so they use the same speed as the general print?

Outer Shell speed: 30

So that could be set to less than the basic print speed (so set to 10 or 15 since basic print speed is 20)?

Thank you for your help.

[Possible Underextrusion & How to Fix]

Hey Guys,

First post here. I am working with a a new Ultimaker 2. Prints were going fine for a while, but I am thinking I now have a problem with under-extrusion. See below:

Settings Were:

Layer Height: 0.08 mm

Shell Thickness: 0.8 mm

Enable Retraction: Checked

Bottom/Top Thickness: 0.08 mm

Fill Density: 24%

Print Speed: 20 mm/s

Support Type: Touching Build-plate

Nozzle Size: 0.4 mm

Support Settings:

Structure Type: Grid

Overhang Angle for support: 60 degrees

Fill Amount: 27%

Distance X/Y: 0.95 mm

Distance Z: 0.15 mm

Can you guys confirm that this is an under-extrusion issue, and what I might be able to do to combat it? I have tried the Atomic Pull Cleaning Method several times recently after a bunch of stuff got melted to the nozzle and I was coming out clean. I have printed a number of times since then, but the under-extrusion seems to have started around that time, and slowly gotten worse. I tried another version of the print with thinner layers and 100% fill. That came out OK, but one corner curled up a lot and the overhang for the cavity in the middle on the underside was pretty rough.

Any help or insight you can provide would be much appreciated.

Thanks,

-Dan
