(About 10mm per second, best to keep it at this speed.)Ĭaption: Every aspect of the cutting process can be controlled from here including the speed at which the laser moves around the project.> Red: A vector cut, a slower sequence that relies on power and speed to ensure a clean cut. (About 20mm per second, best to keep it at this speed.) (About 100mm per second, but can be increased to 180mm.)īlue: A vector engrave, the laser unit traces the shapes drawn in the document to create fluid lines. With the design open you will see all of the strokes, created in Inkscape and colour coded to instruct Whisperer as to how it should handle the job.īlack: A raster engrave, similar to how an inkjet printer sprays dots across a page, left to right, top to bottom. Once selected it will take a short while to open, as Whisperer is working out the design, and will try to render it correctly. To open our file, created in Inkscape, we need to click on Open Design File and then locate the correct file. This will instruct the K40 to ensure it is in the home position and it confirms there is a connection between devices. Open the Whisperer application, and then click on Initialize Laser Cutter. Your K40 is ready to cut! Using K40 Whisperer Once found remember where it is, mark it using masking tape! Place a “sacrificial” piece of laser grade plywood (2-5mm) in the cutting area, and ensure that it is in the top left of the area, use the “Test Laser” to locate the top left of the cutting area. Set the power level to about 20% using the “Current Regulation” dial. The laser unit will “home” to the top left of the cutting area. With installation complete, connect the K40 to your computer via the USB lead and then follow this checklist to ensure a safe power-up.Ĭheck there is water for the pump to cool the laser, if not top up now!Ĭheck the exhaust fan is connected and turn on.Įnsure the cutting area is clear of debris and the laser unit is free to move. For those using Linux, you will need to download the source files and read the README_Linux.txt file, the same applies for Mac (README_MacOS.md) To install K40 Whisperer, head over to the download section of their website and click on the relevant link. To check, open the control panel of your K40 and take a look! Installing K40 Whisperer K40 Whisperer is designed to work with the stock control boards that come pre-installed, such as: This is incredibly handy for my Makerspace as we are using an old Lenovo X61 laptop running Linux Mint to run the laser cutter. Now you might be thinking “But the K40 comes with its own software, can I just use that?” Well, yes you can, but I’ve found that K40 Whisperer is a lot easier to use, and it even runs on Linux devices. In the final part of this series, we finally start cutting things with the K40 laser cutter! We will transfer our designs created in Inkscape to an application called K40 Whisperer from Scorchworks.
