Devfus Foam Crack [upd] Jun 2026

Getting Started with DevFus Foam 2 - Hot Wire CNC ... - rcKeith

Scenario: A homeowner noticed a ½-inch wide crack in the Devfus foam sealing their basement rim joist. Cold air was leaking through.

Instead, he found something impossible. The "crack" wasn't a defect. It was a hollow chamber inside the solid foam, shaped with such impossible precision that it looked like a piece of jewelry. Inside the chamber, nestled in the very heart of the wing, sat a small, metallic cylinder that hadn't been there before.

• Each line should contain one tuple of the form '<current state> <current symbol> <new symbol> <direction> <new state>'.
• You can use any number or word for <current state> and <new state>, eg. 10, a, state1. State labels are case-sensitive.
• You can use almost any character for <current symbol> and <new symbol>, or '_' to represent blank (space). Symbols are case-sensitive.
  You can't use ';', '*', '_' or whitespace as symbols.
• <direction> should be 'l', 'r' or '*', denoting 'move left', 'move right' or 'do not move', respectively.
• Anything after a ';' is a comment and is ignored.
• The machine halts when it reaches any state starting with 'halt', eg. halt, halt-accept.

• '*' can be used as a wildcard in <current symbol> or <current state> to match any character or state.
• '*' can be used in <new symbol> or <new state> to mean 'no change'.
• '!' can be used at the end of a line to set a breakpoint, eg '1 a b r 2 !'. The machine will automatically pause after executing this line.
• You can specify the starting position for the head using '*' in the initial input.
