You'll have to play with the support interface options in order to get the best surface. Check out the "Support Interface Pattern" setting. If you were able to rotate the object by 90DEG you could avoid the supports. But with such a small object it would be difficult to print.
Which printer do you use? Have you considered printing with PVA (if you have an UM3 or S5)?
-
Ok, then it must be something else. Looking at the brim for the object, I can see that it is very spotty. The brim should have a tight surface so it could be a sign for underextrusion. I wonder how the main object print quality is like. Do you see signs of underextrusion there too?

If you can reproduce the error with Cura 3.4.1, could you create an issue on Github? This would help the developers fix the bug.

There is no Ultimaker 3+ extended, I just used your naming without thinking - sorry.
I can't tell what went wrong here. When I load your project, a new printer is created (Ultimaker 3 extended) but the part can not be sliced (see screenshot). I assume something went wrong with the printer creation.
If you don't have other printers defined in Cura, I would suggest to remove the actual version and install Cura 3.4.1 again. Then create a new printer (Ultimaker 3 extended), drag your .stl file (scal it since it is tiny - I guess inch<->cm issue), set the material to ABS (if you really want to print with ABS) and slice again.
Btw. I saw that you also set to print with support with PVA - but the combination ABS/PVA is not supported. I disabled "support" in Cura with your project but the problem still persisted.

@robson This is off-topic but I had a simmilar issue with the pulleys. They were not completely round either and I replaced them with some custom manufactured ones and.... it didn't change anything. If you have problems with printing round objects, at least I can say that it might not be related to the pulleys at all.
If you have problems with round and square objects, post a new thread - I am sure people will step in to help with that. There could be issues like loose pulleys or slicing problems.

Hi,
what did you try and what did not work? What happened? Did you print with support interface enabled and the surface was still bad or weren't you able to get the support material off?

Hi,
visiting https://ultimaker.com/ER26 redirects to:
https://ultimaker.com/en/resources/23162-this-print-job-is-not-suitable-for-this-printer
Did you create an UM3+ Extended printer in Cura? Which version of Cura do you use?
If you use on of the new Cura versions (3.x), you could save your actual project as a .3mf file and attach it to this post so we can have a look.

Hi and welcome to the forums.
The UM3 understands the .gcode.gz format so you should be able to just put the file on a USB stick and print it. Since a plain .gcode file is just text, zipping it with gzip saves a lot of space.
What happens if you print the .gcode.gz file?
-
Hi Robson,
have you tried calling the reseller? Maybe he missed your second mail.
I don't know where you could get the "official" UM2+ fan shroud because as far as I know it is not part of any spare parts kit (well except for the UM2 Plus upgrade kit).
If you don't really need the metal shroud, you could print one yourself. There are many designs on Thingiverse or YouMagine. I used one printed in colorFabb XT for a very long time.

Hi,
under "Support" in Cura, activate "Enable Support Interface". It will be harder to remove the support but the surface of your object should look much better.
-
Hi,
usually this is a temporary problem. Have you tried to restart Cura and access the printer again?
If the problem persists, can you ping the printer from your PC?
-
Hi,
sorry for replying in English, I don't speak Spanish.
Search for the file "cura.log", there should be the clue why Cura is not starting.
-
I'd just live with it. It will look the same after your next PVA print... I tried to keep the BB core clean all the time but I gave up at some point.
-
Hi,
if you use Cura, check the print speed at which it prints the support. I assume it prints way too fast and filament strands are dragged around and clump together.
-
Hi,
sorry for my response in english, I don't speak french. In order to fix the ERR12, take a look at:
https://ultimaker.com/en/resources/23146-max-temp-error-on-printcore
(or https://ultimaker.com/ER12)
-
Why do you need to adjust manually after active leveling? Not that active leveling is perfect but I never needed to manually level the build plate after a print has started.
-
Since you own an S5 too, try to print PVA on the UM3 with the BB print core from the S5. This way you could rule out a print core problem.
-
I sliced it too and found that if you set "SeamCornerPreference" to "Hide or Expose" - or something else than the default, it does not produce a visible seam (at least not in the layer preview - I did not print it).
Oh and btw. I went to Thingiverse to download the Marvin .stl file. There is another "advanced Marvin" which looks pretty neat with dual extrusion ?

Not sure about the order of "-l" and "-o" but this shouldn't make a difference.
Take a look at the "robo_3d_r1.def.json" definition file. It inherits from other more generic definition files and these need to be present in the same directory (well at least it would work if that's the case).

How do you call the cura_engine binary?
Last time I used it, it was something like:
# cura_engine slice -v -p -j /path/to/definitions/file -l model_file.stl -o output-

Check out the verbosiy parameter of cura_engine. It might be that it does not find the definition files.

Hi Heiko,
leider lässt sich das m.E. nicht ohne Weiteres vermeiden. Ich nehme an du sprichst über die "travel" Bewegungen wenn der Druckkopf sich bewegt und zum nächsten Segment springt. Das ist das sog. "oozing" - also das ungewollte Austretten von Filament aus der Düse.
Schau dir folgende Optionen in Cura an (siehe Screenshot). Ich habe hier im Suchfeld nach "retract" gesucht. Interessant ist dabei z.B.
"Retraction Minimum Travel" welches angibt um wieviel sich die Düse mindestens bewegen muss damit eine Retraction (also Einzug von Filament) durchgeführt werden soll. Auch "Retraction at Layer Change" könnte hier im Kontext interessant sein.
Du kannst mehrere, kurze Testdrucke mit diesen veränderten Parameter durchführen.
Falls die Einstellungen in Cura nicht sichtbar sind, rufe die allgemeinen Cura Einstellungen auf und schalte die "retraction" Einstellungen auf "sichtbar".
Grüße,
Stefan

Du kannst in Cura "Speichern unter" oder als Projekt speichern und die .3mf Datei hier hoch laden.

Hi,
this is super weird and shouldn't happen... I'll inform the devs about it. Thanks for finding this bug.

UM2(+) known bugs?
in Firmware
Posted
I can't remember correctly how this bug "worked" but there was something about the print head freezing in place at the end of a print. It was about parsing .gcode files and the fix was to add enough random characters to not trigger the bug. Does it ring a bell?
