Please correct my understanding if it's wrong. Thanks!
Your understanding is correct.

One obvious change to make is to use wider wall lines. I have printed spiralized vases in PETG using 0.6mm wide lines from a 0.4mm nozzle and they are quite watertight and not easily damaged.

Can you please provide some more info? A screen shot or even better, the project file (do File->Save) and attach the .3mf file. thanks.
-
Ah, OK, I missed the fact that you had a zillion bottom layers. No problem, happy printing!
-
That gcode is weird, could it be the zoffset thingy that you are using is causing a problem?
-
Thanks for the file, unfortunately, it uses an unknown printer type so I cannot load the project, just the models. With the project, I can't see what settings you are using. Anyway, I sliced the model using my standard setup and the spiralization looks OK.
Could you please attach the gcode file? That is almost as useful as the project file, thanks.

Hi, please supply the project file. Do File->Save and then attach the .3mf file to this thread. Thanks.

Thanks for the file, yes, I can see what you mean. I don't know if there is a workaround for that in UM Cura but my Cura builds have a setting to prime all the extruders on the first layer. Here I am only displaying the extruder 2 lines and you can see the center of the prime tower is extruder 2 not 1.
If you wish to try my Cura, you can find the builds at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0
Please read the README.md file there before using.

Err, that file has the settings but no models! 3rd time lucky?
-
Sorry, that file is almost completely empty. It contains no model or settings. Load your project into Cura and do File->Save.
-
OK, glad it's solved, happy printing!

Could you please provide an example project file that shows this behaviour? Do File->Save and attach the .3mf file to this thread. Thanks.
-
I see skin in the layer view, did you? How about posting a photo of the failed print? Or maybe give more detail about what has gone wrong?
-
Also, if you can post one of the test print gcode files that would be great because we can then compare it to what Cura is producing. Thanks.
-
Could you please post a sample gcode file that exhibits this behaviour? At least we could then check it for obvious problems.
-
Cura cannot generate G2/G3 gcodes.
-
I've never used this feature but I believe that the order is determined by the per-mesh setting Mesh Processing Rank...
-
Anyway, it looks to me that you are trying to push a lot of plastic, can your extruder/hotend really deliver 16.8mm^3/S ?
The printing temp is hot for PLA so I would have thought that you would see quite a bit of shrinkage as it cools? Maybe it would be worth trying a lower print temperature and reduce the print speed and/or layer height to cut down the required extrusion rate.

What size nozzle are you using?
-
Hello @henderpa, could you please provide a sample project file that exhibits the issue? Do File->Save and attach the .3mf file to this thread. Thanks.
-
Try turning off Use Towers.
-
Don't know why but I wasn't getting any bridging on the top of that model, just ordinary lines. My current Cura is a little different to the UM releases. Sorry I can't provide any help.
-
Hello @Veroo, if you could share that model I can take a look at the problem and see if I can get a good result. Please attach the STL file if possible.

Super thin first layer

Not terribly reliable using paper. Far better is to get a set of feeler gauges and then set the nozzle to, say, 0.5mm above the build plate and then drive the nozzle around manually and use the feeler gauge to check the height in various places and adjust the height screws as appropriate. Very quick to do. I always print on blue tape so I just add 0.1mm to the height to account for the thickness of the tape.
