Outer wall indented lines


Recommended Posts

Posted · Outer wall indented lines


I'm currently printing on a (sigh) Geeetech A20 using (yey) Cura software.

I've been experiencing these lines in the outer walls of my prints for some days now, and i've tried to tweak almost every parameter to non avail.

It looks like some layers are under extruding while others pop out;

doesn't seem to happen in a cyclical manner, just an indented line every now and then.

Retraction and coasting are activated since i'm printing 2 parts at the same time,

although the same thing happens in a single piece print (with these switched off)


If anyone has had this issue before can please give me a hint on what to look for?


checked bowen extruder calibration

keeping the printer safe from environement changes and on firm surface

Using Geeetech black PLA

bed temp. 55°

nozzle 190° (best results so far)

print speed 80 mms

wall speed 40 mms

layer height 0.15

in. layer heigh 0.15

retraction 3.5 mm

ret. speed 65 mms

coasting volume 0.08

min. ammount 0.8

coast speed 100%

compensate wall overlaps (inner + outer) true

all of above been tested in a ±5 range (or in small values for millimeters)


Thankyou in advance

      • 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
