With the right settings, the nozzle will not cool down... which of the "pause" options do you use? There a a few of them you can choose!

Maybe you want to share the STL-file so we can take a look at it?

Pressing the only button there is on your printer should do the trick!

I've opened the STL-files and can't see anything wrong with them... the 3MF-file contains only the objects, not the printer setting (choose for SAVE PROJECT, not EXPORT)... - Leveling the bed of an Ender printer is not that difficult, you do need to have the patience to do it right! I have a Ender 3 Pro and I had to level the bed only 2 or 3 times... first time when I bought the printer, second time when I switched from the flex magnetic bed to a steel flex plate with Lokbuild! The third time when I thought there was something wrong with my printer but instead it was the role of PLA that I was using! * Check if the printer is build the way it should be, everything has to align... there are lots of YoouTube videos explaining how to build an Ender printer and where to pay extra attention too * Check the tension of the belts, too loose will result in bad printings! * Check bed-level... sometimes you have to level the bed a few times to get good result. For my Eder 3 pro I use 2 GCode-files, 1 that moves the nozzle to every corner and center of the buildplate (for leveling) and 1 that prints squares to see if the bed-leveling is done correct or maybe needs some tweaking. Chuck Hellebuyck is the guy who made this files. Files and explanation how they work can be found on his website: https://www.chepclub.com/bed-level.html If you re-upload the 3MF-file I will take a look at it again... But first make sure the hardware is ok, then play with the settings in the software (slicer)...

attach the STL or better the project file (3MF) that contains the to print object and your printer settings... the screenshots of your settings are simply to small to read!

Attach the STL or better the complete project-file that include the object and you printer-settings!

You have to change the print sequence to "One At A Time"... Imported the different object, uanble to slice because the safety-areas overlap... Not able to slice and print! Moved the objects, so there is no overlapping the the safety-areas... Able to slice and print! You will also save some printing time because there are less travels between the different object...

Under "Preferences" - "Configure Cura"... uncheck the "add machine prefix to job name" under General/Opening-Saving files...

Something went wrong with the dimensions... they are way way of for these parts, therefore you have to scale them down like @GregValiant mentioned! @Prolifics, where did you find these files? Are you an Airsofter? 😉

16 characters must be enough... long long time ago you only had 8 characters for filenames.... I still keep filenames as short as possible... So stop complaining and start printing...😉

@jeex, go to the webshop of 123-3D, they sell their own brand PETG and from REAL. I have printed a lot with their own brand PLA! Good quality!

Did you have good results with previous version(s) of Cura? Install THAT version and give it a try!

Which version of Cura?

Telling us only the version will not help to solve you problem! What kind of computer? OS? What is the error you get! Most problems are easy to solve by restarting the computer or re-installing the software.

...don't think so (99.9999999% sure)... you need to redesign those cookie cutters...

The position of the first lines changed during different versions of Cura... I like to maximize my buildvolume, so I moved these lines closer to the edge of the buildplate... sometimes I remove the line directly after it is printed 😉. Compare your Start G-code with the part of my G-code! G1 X5.1 Y20 Z0.28 F5000.0 ;Move to start position G1 X5.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X5.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X5.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line

You will not only have problems with long filenames, when a filename starts with _ (underscore) the file will not show up on the display!

Unthick "add machine prefix to job name" in preferences... or manualy rename each file before saving 😉

No problems with underextrusion with my Ender 3 Pro and Cura 4.7.

Underextrusion is something different than software crashing... You already posted your under extrusion problem in another topic, so no need to post in other topics as well...

That is what IT-specialists call "PEBKAC" - Problem Exists Between Keyboard And Chair... 😉 Why copying files when creating a new printer is easy in Cura? There is not much difference between CR-3, CR-5 and CR-6 like @Torgeir already mentioned.

... what version of Cura? In 4.7 there is no default CR-6 printer, so you probably have chosen on of the existing printers and named is CR-6, or am I wrong?

If you reply in this thread you have the option to attach a file to the message! Simply by dragging it into the reply-box...

Labist/Anet... if you look at pictures of both they look the same... so in theory selecting the Anet ET4 printer should work! Temps of Nozzle and Bed are of nu influence of your problem, the drifting off... Why is it doing this? You say everything looks okay in Cura, but when printing it goes wrong! We have to figure out what happens. So upload the 3MF-file so one of the experts on this forum can take a look at it and see if they can spot something!

When you start with 3D-printing, you will waste some filament during the finetuning of your printer! Please add photograph of what happens, I have no clue what you mean by "drifting of"... When you have your file loaded in Cura, do a "save project" and upload that .3MF-file here!
