brittle printout

[rioz 0]

I use default setting in cura 4.4.1 and get brittle printout.  I tried to increase printing temperature between 210 to 230 but still get the same result.  Any one can give me some advice to solve it.

This is severe underextrusion.  This is less than 50% extrusion.  So you get droplets of filament coming out of the nozzle followed by an air gap and then the next "post" grabs the next droplet.

 

I'm going to guess the problem is that cura thinks you have 3mm filament when in reality you are using 1.75mm filament.  Are you using a 1.75mm filament printer?

Yes, I am using 1.75mm filament.  How can I fix it if your guess is correct.

I don't know - look at the settings in Cura - try to find out how the filament diameter is set.  I did this once and it took me an hour I think.  It was confusing.  I had to change it in 2 places - both in the materials (the materials have a diameter) and in the printer settings.  I may have done more work than necessary.

 

Once I understood that it was critical to fix this in Materials it didn't take long.  I then just had to find a way to get cura to accept the material for my printer.

Thanks sir.  I fixed it by setting the filament diameter in cura.
