# Slicer If we open this up in a gcode editor, we can see a fake flag there. The hint hints at the movement speed of the arm, and so if we do a bit of research into this, we can see they are represented by "F" values. Therefore, we extract these from the gcode file. Most of them are either `F10500` or `F2400`, but some of them appear to be quite small, and some even appear to be within the range of numbers for standard ASCII chars. Perhaps there is something hidden in those values...\ So, we filter out the `F10500` and `F2400` values.\ At the end of the output, we can see a list of values that appear to be within the ASCII number range, so I converted these numbers to ASCII text to get the flag. ``` F116 F106 F99 F116 F102 F123 F109 F52 F110 F121 F95 F108 F52 F121 F51 F114 F115 F125 ``` ## Flag: tjctf{m4ny\_l4y3rs} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://the-winrars.gitbook.io/writeups/2020-writeups/tjctf/slicer.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
