Unidentifi3d Flying Object

Printer

After looking at the gocde content,we find some useful information in the end of the file.

;SETTING_3 {"global_quality": "[general]\\nversion = 4\\nname = Extra Fast #2\\n
;SETTING_3 definition = geeetech_A10M\\n\\n[metadata]\\ntype = quality_changes\\
;SETTING_3 nsetting_version = 16\\nquality_type = verydraft\\n\\n[values]\\nsupp

We know that geeetech A10M is a printer,and it's the flag.

flag : geeetech A10M<br><br><br>

Layer by Layer

Look at the document,we know that gcode is a language that is telling the machine tool what type of action to perform. So I use Ultimaker Cura 4.10 to view the file.

Notice the name of the challenge, we can use Cura to look at every layer seperately.

There is the flag

flag : CTF{flying_saucer}
