This thread helped me out a lot!
Had a similar issue and couldn't find the cause until I came across this thread.
So, thanks!

any news on Cura fixing this bug?

So look at your retract and z hop settings as well as your top and bottom layer settings and see what they all are set for.

I have disabled retract and z hop and now the gcode looks fine, there is nowhere a massive feedrate to be found. It looks like a cura bug to me.....

I have tried multiple stl files, but i still need to slice them with cura so it doesn't isolate that problem. I am testprinting the dog now, so far no problems.

I have been digging in the gcode file itself and i think i might have found the problem. Here is a snippet:

Each argument tells the printer about how to execute the command. The arguments start with an English letter and then specify a value. For example, X-9.2 means a destination X coordinate of -9.2. F3000.0 means a Feed rate(F) of 3000.0. E0.0377 means an Extrusion(E) of 0.0377 mm.

In this code i see a feedrate of roughly a quadrillion. I dont think the printer likes that very much and this could be the reason for the stall. Question is, how did this come about? I'm printing at first layer 20 mm/s, after that 60. Temp is 60C and nozzle is 200C. I have a feeling it might have to do with retract and z hopping. It always stalls after a certain part is complete.

What do you guys think?

This sounds like the controller is over heating especially if it get worse with time. Are you printing over USB? A bad cable or cable that is too long as in over 10 feet can cause data loss or corruption and also cause this behavior. Finally does it do this on all STL files or just this one as Kronik suggested.

Lastly it could be a failing power supply on it's way out causing glitches in the logic on the controller.

I have been printing for a while now and everything is going pretty good. Tried a lot settings, made a lot of mistake and learned alot along the way. The printer is now perfectly set up, calibration is perfect and everything is perfectly flush.

Recently i have been having problems with my Ender where it just stops for 10 seconds, makes a weird whirring sound like the stepper motors are unsure of what to do and then continues. I made a video(sorry for the music). This happens after about 5 minutes, and after about 5 hours into printing it occurs more and more to the point where i have to stop the print. I tried different design and they all run into this problem. I changed the extruder and made sure there are no other problems. It happens at the same exact time in this print.

I feel like the only explanation for this is in the Ender 3 or the cura slicing software i am using. Does anyone else have this problem?

Hope someone can help!

P.s. I added the file, maybe someone can see whats wrong with it
