<p>Sometimes Cura will slice a model and have failed lines of code. After discovering this problem I have tried re-slicing and then the code will come out fine. The first picture below is the failure point in the code from the first time I ran Cura's slicing. The second picture is the exact same model that I ran a second time through Cura and it came out fine. Is there any settings/reasons as to why this is happening?</p>
<p>Note, that I am also using an Ender 3 v2. For the time being I suppose I will have to look at the full code ahead of time to spot failure points.</p>

Which version of Cura are you using? Is it the most recent? Have you tried slicing the same stl file with another slicer? What else have you tried?

Do you write directly to SD card? That looks like a writing error!

(Asked by: username_0 on 2022-01-27)

Sometimes Cura will slice a model and have failed lines of code. After discovering this problem I have tried re-slicing and then the code will come out fine. The first picture below is the failure point in the code from the first time I ran Cura's slicing. The second picture is the exact same model that I ran a second time through Cura and it came out fine. Is there any settings/reasons as to why this is happening?

Note, that I am also using an Ender 3 v2. For the time being I suppose I will have to look at the full code ahead of time to spot failure points.

The random appearance of the commands makes this appear as a writing error. I have had these happen in three cases:

* When I sliced an object and then saved to the SD card but removed the card before saving finished, the resulting file was corrupt and at times wouldn't even print.
  + Solution: Wait for Cura to tell that saving finished, then use eject before removing the card.
* When I sliced and saved, waited for completion, and yanked the card too quickly after that without using eject.
  + Solution: use the eject card button.
* When I used an adapter with a bad fit or connection to the SD card.
  + Solution: reseat the SD card or use a different adapter.
