Trouble getting smooth surface PETG  

RE: Trouble getting smooth surface PETG

The blobs on the surface are most probably caused by moisture. Dry your filament and try printing from a a dry box. PETG can absorb moisture rather quickly...

thanks for the reply. Will try to dry the filament and see if the print improves.

@smart-site

It's always a good idea to dry filament, however I suspect you may be having another issue, from the look of your images you seem to be under extruding, and your first layer seems a bit high. two separate problems, make sure that you have your Z adjusted properly for the PETG your using, as I mentioned it looks like it needs to be lowered a bit.

If post a Zipped up .3mf project file exported from PrusaSlicer, I'll take a look and see if I can help. The .3mf file should be setup as you would when trying to print the part and will allow us to see all the settings as they pertain to the model in your project.

Note if you do not Zip the file the forum server will not allow it to be posted.

Hello Swiss_Cheese,

This is the 3mf file, could be that some settings changed a little since the last print.

Appreciate the response.

RE: Trouble getting smooth surface PETG

I'm going to +1 what @swiss_cheese said.  Your first layer isn't terrible but could be taken down a touch.

RE: Trouble getting smooth surface PETG

made some extra prints. First layer seems better. Still to high?

Side of the calibration cube is not straight. Contains some bumps?

Also top layer is a little rough.

Any thoughts?
