Yeah Me again trouble in paradise

[NelsB54 0]

OK my UMS5 is doing the same thing again I think it Under-Extrusion.  So I have installed a new print core, new filament, cleaned the feeder housing, and adjust the tension on the filament.  Filament (Tough PLA) temp 210-215,  printed speed 40-50  I have almost tried everything nothing is working,  any other ideas.  Oh yeah and the system is only 8 months old

Hello,

if you have a project file and a picture of the print result, people can help you.

Depending on what kind of projects you print, for example, a too long retract setting can also give the impression of underextrusion.

Many greetings

Hello

yes pidy. Under extrusion in all (inner- outer wall and infill).

Have you tried to print on the second feeder. So you could narrow down the problem for now.

Many greetings

I skimmed through your previous posts and didn't notice mention of how you're keeping the filament dry during prints, so I figured I'd ask.   Do you have a dry container that sends material to the feeder, or is the spool out in the open?   I overlooked this subject for quite a while early in my 3DP career because of low humidity in my area.  Then we had high humidity weather come through for a month and I didn't connect the dots to realize it was a cause for some poor prints.    Taking pains to keep filament dry helped out a lot once I got onboard with the idea.   Best of luck in resolving your issue!

What layer height are you printing at?

The bigger the layer height the higher a print temp is needed or slower print speed, so that the filamant as time to melt in the hot zone.

 

Have you tired to print a temp tower? because sometimes you have to print at a higher temp and don't always take cura temps as a given.

The print indeed looks horrible. 

What filament are you using? 

What printing profile do you use in Cura? (Always start printing with the default profiles)
