Posted · help with settings to fix print quality

I am having issues with prints delaminating and being very weak (PLA prints feel soft and spongy and are easily crushed by hand).

See the attached image for examples. the 3 prints to the left were stopped after the first layer due to clear gaps. The one on the right was allowed to continue but was ultimately a mess.

 

My first mistake is too many variables changing: I lost my cura settings, have a new brand of pla filament, and have also recently leveled the bed.

 

I'm not sure if it is a case of poor quality filament or some settings I have lost in cura.

 

I'm hoping that soomeone with experience can take a look at the attachment and be able to advise what is causing this? Is this just a case of underextrusion or something else at play?

 

What I have tried:

- changing temperature up and down (200 to 220 degC). doesn't seem to help but ther is stringing at the temps tried

- levelling bed - tried with small gap between nozzle and bed and a slightly larger gap

- change filament diameter in materials screen (filament measures 1.70mm with calipers)

- change flow rate to 115% and 140%

 

Machine: Creality ender 5

Material: Sunlu black PLA 1.75mm

 

 

Can someone point me in the right direction of settings to tweak in cura to try and fix this?

 

Thanks

    What I see on the picture is under extrusion, so your printer doesn't extrude the right amount of material. But I don't know the Ender printer, so I cannot give you any advice.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
