Unknown issue affecting print quality I have been having issues with a vase print using a FlashForge Creator Pro. 
I am using the default slicer for the printer(FlashPrint) because the Creator Pro only accepts .x3g rather than .g/.gcode.

The issue is that the printer seems to be both under extruding and over extruding. 



I am printing ASA filament at 0.18&nbsp;mm layer height at 240&nbsp;&deg;C with a heated bed at 110&nbsp;&deg;C. I am running the print with the fan on. I am also running at 80&nbsp;mm/s print speed.

I have tried both lowering and raising the temperature, changing the print speed from 80&nbsp;mm/s to 60&nbsp;mm/s, and changing the extrusion multiplier.

At this point I am not really sure what to do in order to get this to print nicely, any advice would be welcome.



After a few more prints and the link that "E-Doe" posted I am beginning to think that the problem might be with the z-axis. My reason for thinking this is that the layers that bulge out do so consistently for the entire layer and then stop for a bit. I think I also ruled out temperature variation. I measured the temperature in the enclosure with a separate device and it stayed pretty constant the whole time.

Not really sure how to fix that but I will call this question answered.

It seems like your problem is inconsistent extrusion or temperature variation. From the photo you posted I guess that you use a big diameter nozzle. Keep in mind that your extruder might not be well equipped to deliver such a large amount of plastic consistently. This most likely is a problem with the heating capacity.

You can try to lower the speed even more to give your extruder more time to heat the plastic.
