VisiCut manual · t-oster/VisiCut Wiki · GitHub
If you find that VisiCut does not do what it should, please create an Issue instead of documenting the workaround here. Especially when using inkscape, it is recommended to use the VisiCut extension instead of opening the svg file directly from VisiCut. The extension does some cleanup, converts text to path etc. In VisiCut, select Extras ->, Install Inkscape extension… to install the extension to Inkscape. Then you can restart Inkscape, open a file, Extensions ->, Lasercut ->, Open with VisiCut. For each combination of material and thickness, different laser settings (speed and power) are stored for each laserprofile (cut, engrave, etc.). The operations like cut, engrave, etc. are not fixed, but you can edit them and create custom ones. For example if you cut with too low power, you just mark the material. Cut: Cutting through the materials. Mark: Leaving markings on materials by cutting with less power or more speed. Engrave: Take a bitmap and ‘dither’ it to black or white pixels (using different algorithms with different results: Dithering algorithms) Then make a raster job where every black pixel is ‘laser-on’ and every white pixel is ‘laser-off’ Resolution: Resolution of conversion. Lower resolution makes bigger pixels and less vertical lines. Less vertical lines means you might see the actual lines and you cut less deep. See following image, top gradient was 500dpi, bottom 200dpi. Using resolution of 100dpi, 200 dpi and 300 dpi (Floyd-Steinberg dithering lagorithm): Engrave 3d: Take a bitmap and convert it to GREYSCALE. Make a raster-job where every pixel is black=laser 100%, white laser=0% and all in between linearly interpolated. The LAOS firmware does not support engrave 3d by default (yet), there is only some old code, converting the raster to a vector job it also doesn’t overshoot, making it cut deeper at the edges. I do not know if it works properly, because this mode is rarely used. The Epilog cutters however fully support engrave3d. You can adjust the settings of every laserprofile. Below are the properties. You can add multiple treatments to one profile, which is useful for cutting very thick material in two steps. Power: Which percentage of max power should be used. Speed: Which percentage of max speed should be used. Focus: Focus of the laserbeam. Focus is counted from the top of the material, highter numbers mean greater distance between focus lens and object. Focus -1 means that the focus is inside the material, 1mm below the surface. Frequency: TODO Ventilation: Whether the Lasercutter should ventilate. Purge: TODO With VisiCam you can see your lasercutter bed as an image inside VisiCut and use it for positioning your objects. If setup correctly, the precision is within some millimeters. VisiCut fetches the image via network from a HTTP server (VisiCam). The server address can be configured in the lasercutter settings, where you can also find a button for auto-detection. The VisiCam server runs on a normal Linux computer and fetches the image from a USB webcam. You can also use the Raspberry Pi 2 with its camera module. The settings are stored in a .visicut folder in your home directory (~/.visicut for Linux/Mac, %USERPROFILE%.visicut for Windows). Additional space per Raster line: How much the laserhead overshoots the drawing so it can accelerate and deaccelerate. This makes sure the laser doesn’t engrave deeper towards the edges because of speed differences. Debug output file: If you fill in a filename here VisiCut will create a text file with the code that’s send to the lasercutter. This file is placed next to the Visicut.jar file. In the case of OS X you’ll find in by right clicking on the application and selecting Show Package contents. Then you’l find it in Contents/Resources/Java. Source.
