Issues with Gerber drill export, cannot see the file in GerbView

[electrophile]

I’ve been having some issues with a drill file. When I export it as a Gerber drill file and then try and open it in GerbView (or any other Gerber viewer) I get the following error:

Here are my export settings,

And here is the actual drill file,

18650-charger-revA.drl (674 Bytes)

Here is the KiCad version info:

I did a download of your file and doulble clicked on it.
Looks like:

Your error messages almost spell like the 2nd line of the file:

; DRILL file {KiCad (5.1.5-0-10_14)} date 2020 May 12, Tuesday 10:38:07

except that the capital “D” and “I” are missing.
Looks like it is somehow not recognized as a comment line.

It just could have something to do with the way line endings are handled on different operating systems.

I tried the file on the reference gerber viewer, and it displays it without complaints. Probably the file is OK, this viewer tends to complain on format violations, even if it displays it as intended.

I see. I sent the files to the manufacturer and the boards have come out okay. I guess no cause to worry because they won’t display okay.
