Can´t fix overextrusion in certain spots

Posted · Can´t fix overextrusion in certain spots

Hello community,

I am having an issue with my prints recently where I seem to have overextrusion and the print surface gets rough, but only in certain spots.

I have analysed the problem to occur either where two "fronts" meet or where the printer has to make fast direction changes in order to fill the last small spots left in a layer. Its has to be either one or the other of those two. Same with first or last layer it happens on both in the same spots.

What I have tried so far is to lower the esteps which didnt help. I increased the printspeed because I thought maybe the printer extrudes too much when he goes too slow in a small area (which would be a calculation issue then), didnt help. I lowered my printbed a bit, didnt help and I am having the issue also on the top layer like I said. I am using cura right now, if anyone wants to see my settings I can provide those

If anyone has had this issue or maybe has an idea I would be grateful for any help.

 

Picture for better understanding:

I marked the "fronts" I mentioned earlier

Last layer (I lowered the esteps here drastically already)

      • 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
