Notes on my TimSav

A few years ago I made a TimSav foam cutter CNC. These are my notes on it, because I keep forgetting things.

• It runs FluidNC.
• M3 S200 enables the spindle at 20%, M3 S0/S0 disables it, M5 halts it.

To generate the Gcode, I use a program called LaserWeb. I have a few notes on it:

• After you load an SVG, you need to click the leftmost button below the SVG, with the three cubes. This will select all the paths to generate movements for.
• You need to click "Create single" to create a path to mill.
• I use "Laser Cut" as the tool.

I created a small script, cnc_unwanted_moves, to remove unwanted tool off/on at each corner. I won't share it here, as it's too specific to my configuration, and probably useless to anyone else.
