· Gaps in top and bottom layers, no under-extrusion
Here are some possibilities:
1) Partial clog: Try a Cold/Atomic pull method to clean the hot-end
2) Incorrect Nozzle/Filament size set. Make sure nozzle size is correct for you printer and Line Width is the same, or slightly larger than nozzle size
3) Printing too fast: try a slower overall Print Speed
4) Slipping/Gummed up Extruder gear: check/clean the extruder gear and idler wheel of any gunk built up on it. Also try tightening the pressure knob. Of course, it could be too tight and the filament is not sliding past on the idler wheel.
5) Printing PETG too hot or its contaminated with moisture: Do you hear popping when you're printing? Do you see little explosions of vapor when it extrudes filament? Is the filament rough (not smooth) when you manually extruded a few centimeters? These are all signs of either printing too hot or having filament that's absorbed too much moisture. There are multiple Googleable sites on how to dry out PETG. Or try printing 5-10c cooler
6) Printing too cold (yes, could be that too): do your parts delaminate easily? If you are printing too cold, then the extruder has difficulty pushing the filament through and can under extrude (even if the sides look OK). And if the filament is too cold out of the nozzle, it will not laminate properly to the under layer.
7) Your hot-ends thermistor is going bad and not reporting the temperature correctly: This can cause an overheat or underheat and show the same results. Had this happen to be and had to replace the thermistor and recalibrate.
That's all I can think of at the moment!

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
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.
