Unable to overwrite previously exported Gcode of the same name with SuperSlicer

[Stefkeys]

Unable to export Gcode file if I have already exported a previously sliced file of the same name. I believe this is due to the .sqv.bak file that is saved along with the Gcode file. If I delete the previous .sqv.bak I am then able to export with the post processing script.

Post-processing script C:\Python310\python.exe C:\Users\acste\Documents\FastGyroidInfill.py on file C:\Users\acste\Desktop\3D printing\GCode\Eevee_Switch_Stand.gcode failed.
Error code: 1

Running script in CMD

Traceback (most recent call last):
File "C:\Users\acste\Documents\FastGyroidInfill.py", line 16, in
os.rename(sourceFile, destFile+".sqv.bak")
WindowsError: [Error 183] Cannot create a file when that file already exists

During handling of the above exception, another exception occurred:

NameError: name 'FileExistsError' is not defined

Seems like you're using python2 and not python3 as NameError: name 'FileExistsError' is not defined is typical of python2.

I definitely had Python 3 installed. But I went ahead and removed all Python instances and reinstalled 3.10.1

now I get this error

remove on file from your command line ;)

Gosh darn it! I was scouring those lines to find "on" and my eyes failed me miserably!

It works!
