  • What am I doing wrong

    Hey all
    Can someone explain to me why it will be as in the picture, I have a brand new PLA Filament installed and I have made a new Cura profile that I have received help with, what am I doing wrong?

    I can't positively say what your problem is since I do not have the same printer. I did experience a problem with a new filament. It really was a PLA+ I wound up reducing the flow about 30% or points, having it close to 100% instead of a very higher flow rate for the filament I had been using. I also dropped the temperature by 15 degrees. I also slowed down the print speed. One other thing I did was to raise the initial layer height by 0.02 mm. This also solved a problem I was having with this filament of "bulldozing" the nozzle was doing. My initial thought was that after the new filament was heated and passed through the nozzle it was expanding. The changes I made with this PLA+ filament seems to also make straight PLA filament seem to be better. I am using Cura and I have noticed that changing between versions, even though I record and import to the new version there are some animates like in Cura 4.11 I have "Initial Layer line width" of 100% and in Cura 4.12.1 it is set to 130%. This tells me even though exporting and importing profiles to a newer version not everything is going to be the same. Overview: not every filament is the same and not every upgrade is the same (settings).

      Does other PLA filament print the same model properly?

        This is a longshot, but it happened to me recently.
        I accidentally placed TWO identical models in the identical spot in the slicer. I guess I hit paste twice or something. It was invisible the the naked eye.
        The print was coming out like that above. I could not figure it out until I watched it print the first layer, then print it again without moving the Z axis. Then the second, etc.
        Unlikely that's the problem here, but it looked similar, and I wasted a lot of time looking elsewhere.

          It looks like the temperature is bogus. If set right, check if the sensor is mounted properly.

          If it got loose a cushion of air is insulating the sensor and the temperature is way higher than shown on display.

          Also check the cooling fan. It may be blocked or disabled in slicer.

          At least this is what I would check first.

            Thanks for the help and answers everyone

            I have not used the printer for a while so I had to update with a new Ultimaker Cura 4.12.1 and found DRVax cura profile and at the same time I bought a new PLA Filament and tested have also tried with another PLA filament and it is the same, I did a new PID Tuning and thought it would help, it might have something to do with the new Ultimaker Cura 4.12.1 that I installed, so I'm glad someone can help me

                Just a thought. Make sure the nozzle diameter is set correctly in Cura.

                Cheers

                P.S. -- Did you calibrate the extruder steps?

                  Good one. I always forget that. Cura defaults to 3mm filament.

                    The nozzle size issue has caught me multiple times. Thanks for pointing it out Geit
