The laser cutter is a CNC machine that uses a focused, high-energy beam of light to remove material. It can make very precise cuts in paper, cardboard, wood, acrylic, and other materials. See the section below for a full list of what works well.

K40 Laser Cutter Area

Restrictions

The laser cutter is available to members only. Non-members may operate this equipment only in direct collaboration with an active member.

Training

Setup

  1. Ensure that the Laser Cutter and the Laptop are plugged into the power outlets behind the workbench.
  2. Connect the blue USB cable from the Laser Cutter to the Laptop.
  3. Power on the Laptop. It should log in automatically.
  4. Turn on the wall switch for the Laser Cutter and its exhaust system. You should hear the water pump running below the workbench. Do NOT operate laser if the water pump is not working.
  5. Power on the Laser Cutter.

Operation

All necessary software is installed and configured on the laptop at the station. You can either perform vector cuts with an SVG image or perform raster operations with a bitmap image (JPG, PNG, etc.). You will have to convert your graphic into machine instructions, g-code, using the instructions below.

Graphics Preparation

  1. Using the shortcut in the menu on the left, open Inkscape and load your image. The document is already sized to match the cutter area of the machine (300mmx200mm).
  2. Open the Layers dialogue by clicking on the Layer > Layers... menu or with Shift+Ctrl+L.
  3. Rename your layer in the following format, where the 10 represents the power level of the laser, 1000 is the feedrate, and 30 is the pulses per millimeter: 10 [feed=1000,ppm=30]
