Print file with '#' in name

[sharpner]

What happened

Uploading a file with # in the filename works, but it does not get a preview image, see the difference between the files:

Trying to print it anyways results in:

After some testing I figured out that when the filename of the gcode contains the # special character, it won't work.

Client

Mainsail

Browser

Safari

How to reproduce

Upload a gcode file with # in the name. Can by via web interface or directly onto the host (I did it via samba share) does not matter.

Hi. It appears you have two different issues, however I don't believe that either is specific to a bug in Moonraker.

With regard to the missing image, I can only speculate without a log, but I suspect the frontend is not properly escaping the # when requesting the image.

The larger issue, which likely makes the image problem moot, is that Klipper cannot accept a # as part of a gcode command parameter. Thus, when Moonraker attempts to run SDCARD_PRINT_FILE FILENAME=..., you get the malformed command error.

Hey, thanks for the answer!

Makes sense, I would already be happy if the frontend would let me know that # is not allowed when uploading an image - took me too long to find the error

I believe that this may be resolved in Klipper, so I am going to close this.
