Small layer-shift like features in parts

Hope you guys can help.

 

We've had our S5 for about eleven months and when I'm printing parts with holes or features in, I'm often getting an artifact similar to a layer-shift just in the layers with the hole or features in; once the holes are printed it returns to its original routing.. I've been in contact with my reseller's help desk and after their advice I've checked the short belt tensions, checked the squareness of the pulleys as best I can and the x/y rails are freshly oiled. I was using a custom profile too, but the only things I've ever changed from the recommended settings are wall thickness, top/bottom layers and infill patterns. (The reseller suggested that the recommended settings may remove the issue. I'm still in conversation with the reseller on the subject in the mean time).  I've never fiddled with print speeds so I've always kept them as per the profile. Not everything I print comes out with these artifacts though, it mainly seems to occur in the front third of the print surface. smaller parts right in the middle seem to be unaffected. I rarely print much that goes to the back of the bed.

 

The part I have in the pictures is one that I threw together in fusion 360 to attempt to show up the issue.  I'm using Ultimaker Tough PLA and the "fast" setting in recommended settings.

 

Has anyone come across similar issues and how did you solve it when you did?

      • 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
