Receiving error "Could not find the first line of the end gcode block. Missing ; Filament-specific end gcode comment."; however, the line is in the g-code

[SpoolItUp]

As mentioned in the title, I am getting the error that the "; Filalament-specific end gcode comment" is missing; however, it's in the the g-code. Sliced on Prusaslicer 2.8.1.

I have the same issue PrusaSlicer 2.9.0
My gcode

...
;TYPE:Custom
; Filament-specific end gcode 
;END gcode for filament
END_PRINT
...
; end_filament_gcode = "; Filament-specific end gcode \n;END gcode for filament\n"
; end_gcode = END_PRINT
...

Looks like a space has been added at the end of the line:

Original:

; Filament-specific end gcode\n

New:

; Filament-specific end gcode \n
                             ^

The lines are not exactly the same so they fail to match. I could make this check more lenient by allowing additional whitespace at the end of the line.

Before deciding what to do, I would really like to understand is how you got this extra space in there? I have 2.9.0 and I don't see it in my sliced GCode files with the Prusament profiles. What filament profile is this?

Thank you, this helped

how you got this extra space in there?

I Imported custom profile provided by my teammate at least one year ago

also I added manually to .gcode fille

printer_model = Kingroon KP3S Pro V2

Because my Slicer don't provided this value
And I got error

Test pattern generation failed: No max value found, all values are null or 0!

And I guess it's because this printer is not supported but it uses standard klipper commands
