I am not sure if this is under extrusion. Have you checked your x/y belt tension too? Is there a play on the axles?
Are there any differences when you print slower?
-
I can just say again, use ONLY the default settings, nothing else for the moment. There is also no need to adjust some settings to get a better adhesion or to compensate your bed leveling. It seems that you bed is not leveled correctly, try it again on different points with a sheet of paper to get a well leveled bed. And also clean your bed with alcohol,
Your first layer should stick very well on your heated bed when leveled correctly. For me it sounds that your nozzle is too far away from the bed and therefore the first layer gets off. I don't know your printer, but if you have a removeable build plate, then you should normally level your bed every time you remove the plate, otherwise you could get problems.
I guess your printer is not calibrated very well and you have compensated this with some software settings in the past which you cannot remember currently. That's the reason why your old gcode files are ok and the new ones not. So we should first find out, what's the problem with your hardware and go step by step to the next issue.
So your first todo for tomorrow is to level your bed and then make a test print with ONLY the DEFAULT settings, without adjusting here and there. If your brim and first layer still not stick to the bed, level the bed again, bring it closer to the nozzle and print it again.
And "Prost" if you currently sitting with a bottle of beer near your printer 🙂

It is not so complicated as it seems on the first sight. You are right there are hundreds of settings you can adjust, but you can start just with the recommended settings which means infill %, support yes,no and choose a default profile. With these settings you can print 95% and the rest is learning by doing.
Search for a small object and use it to test and to play with the settings until you get a better feeling.
Good luck and have fun with your printer.

That is strange, I have never seen it before, sorry!
-
That looks good, so the settings you have are a good start.
With plain I meant the flatness of the bed. It is not always really flat, but you could check it if you put a ruler or something else on the bed.
But do you have now, after the successful print, additional problems or is your initial problem solved?
-
Post a picture what you mean, I think it is easier.

The strange thing is that the object looks OK in Cura, but when printed it seems to be printing a solid object.
If you look at the STL-file, you'll see that the bottom of the bin is just 0.5 mm, when printed I interrupted it when there was already a layer of more than 2.5 mm.....
It is not strange, it works as designed. I have checked your STL in Fusion 360 and the bottom of the model has a thickness of 3mm. The total height is 12mm and the inner height is 9mm.

When you switch the tab to customize you find all settings and their values. The recommended tab with its settings just set the values in the customize tab.

I have no idea where that is though. @gr5 knows such things.

Next step would be to post your Cura project here, then we can see also your settings.
-
I just put your STL file in Cura 3.6 and pressed prepare 🙂 then checked the layer view.
-
@Andy6583 Please print the object with a default Cura profile, do not change anything else and post your result.
You said you have to solve your brim issue, this is not an issue you have set the first layer height to 0.8 which is too much, so leave everything default and try it again. I still guess you have some strange settings which cause this problem, that's why I want that you use just a default profile.
-
The first object polssteun_bak.stl is ok in my Cura 3.6 and was sliced normally, but the wall is a little bit thin.
The other STL has a problem, if you check it in X-Rax view you can see that there is a problem (not watertight) in it. And I get also a solid model if I slice it. So this object needs some repair.
-
Ja mit dem Wert kann man sich sicher spielen und weiter rauf setzen, ist glaube ich eher sehr konservativ eingestellt.
-
Ja gibt es, "Maximum Retraction Count" damit wird verhindert, dass du zuviele Retractions am gleichen Stück Filament machst und das Filament möglicherweise "abgefräst" wird vom Rändelrad.
-
I didn't something special, I just selected the profile "Draft" and reduced the top/bottom layers, but just of speed. That's all.
I attach my saved Cura project file, you cannot use it directly I think, because it is using my printer, but hopefully, you can open it to compare the settings. It is a Cure 3.6. project file. UM2GO_Skipjack1Hauptschott.3mf
I have seen you have enabled support, why? it is not needed for this object.
Try a print with default settings of a Cure profile, do not change anything except to uncheck the build plate adhesion, because you don't want a brim I think, otherwise leave it as is. You can adjust the infill percentage if you want, but do it only on the recommended settings tab.
And again check your filament/material diameter you have configured. If this parameter isn't 1.75 or 2.85 (depending on what you use in your printer).

Hehe, I am proud looking forward 🙂
Additionally some screenshots of my settings:

Welcome Darren and have fun with your new printer!
You are absolutely right, the community here is awesome and beats all I have seen ever.
-
OK, here the finished print, I forgot to stop it at half of the print, so it was finished normally. Don't look about quality, was printed as a draft, fast and with only 2 shells.
-
STL is fine no problems and it prints also very well:
I will post another picture later when we can see more, but I can definitely say, it is not the STL file, it is fine.
You should really check again the settings in Cura, and use only default values for a next test.
-
Dicke der ersten Schicht von 0.8mm ist etwas extrem, das wird dein Drucker nicht aus der Düse bringen. Verwende die default Werte, vor allem so lange dein Problem nicht gelöst ist.
Ich schau mir einmal dein STL File an.....
Ups, sorry, forgot that we are in an English thread:
First Layer Thickness of 0.8 is a little bit too extreme, better use the default values here.
I am now looking into your STL file.....

aber nur mit sehr viel Kraftaufwand nach Vor und Retour der Y- Motor blockiert praktisch.
Ich kann dir nicht viel helfen, aber das Blockieren ist normal, da die Stepper Motoren dann schon Spannung haben und damit die Bewegung blockieren. Sollte eigentlich beim anderen Motor auch so sein.
Zum Rest kann ich nichts sagen, da ich keinen UM Original + habe.

But upload the STL file from the round part here, then I can check it or print it if it is not too big.
-
You can check your STL file here for example, it is free, you must just create an account:
https://service.netfabb.com/login.php
And in case it is damaged, you can repair it there too.

It looks like you have massive problems with your extrusion, so normally I would say, check your nozzle, feeder gears and so on. But you said you have checked it and its ok.
Then the material itself could have problems, bad quality for example.
But it is strange that you say, if you print an old gcode file, it is ok. So you just print an old gcode file with the same material and nozzle, I would say it has nothing to do with your hardware.
What about the other settings, material diameter setting is correct?

Shows also some extrusion problems, but not so much.
Do you print with the same speed? Try to print slow, about 30mm/sec and check the result again if it is better.

Can you post a picture of the grinded filament?
