![]() ![]() When I first started using GRBLControl with GCode generated by the 305 Engineers GCode Generator for Inkscape extension, the image would not appear in the visualiser window.Inkscape is a free, Open Source vector art program. The code would appear in the bottom window but no image. Open C/Program Files (x86)/Inkscape/Share/Extensions and look for the 305 Engineers GCode files. The file you need is: raster2laser_gcode.py Step 2. Make a copy of it and keep it safe in case you need to replace it at some time. If you are using the 64 bit version of Inkscape it will be in C/Program Files/Inkscape/Share/Extensions Step 3. Scroll down through the text until you get to here: #Configurazioni iniziali standard Gcode file_gcode.write(' Generated with:\n "Raster 2 Laser Gcode generator"\n by 305 Engineering\n \n \n \n') #HOMING if = 1: file_gcode.write('G28 home all axes\n') elif = 2: file_gcode.write('$H home all axes\n') else: pass file_gcode.write('G21 Set units to millimeters\n') file_gcode.write('G90 Use absolute coordinates\n') file_gcode.write('G92 Coordinate Offset\n') #Creazione del Gcode Step 5. After the last entry that says coordinate offset\n') press enter to make a space and type in: file_gcode.write('G0 \n') file_gcode.write('Z0 \n') Step 6. ![]() Close the file and when asked if you want to save it click YES. To see if it works open Inkscape and create your image/design. Then click on the Extensions menu and select the 305 Engineering extension and then click Raster 2 Laser Gcode generator. Enter an Export directory to save the file to, give your file a name and set any required settings to suit your Laser engraver and click Apply. ![]() Close Inkscape and Open grblControl and drag and drop your generated file on to the main window. If the image shows up in the visualiser window it is working. The image may appear with vertical lines / gaps in it, this is not a problem. The image will still burn correctly.Couple of week ago, I started working on homemade CNC plotter that uses stepper motors form old CD/DVD drives. At some time, controller was implemented and construction was solid, so that was a good time for a test run. How can we generate G code from an image? But what to print? There are couple of web sites that can generate G code from string, but what if we want to plot some image with CNC plotter. In this post I will try to explain the process that I have found out to be very good in creating G code from an image. I wanted a solution that is free and easy, so the choice came down to open source software. I’m not saying that this is the best way, but until this point, it is the best way I know. So please, if you have any other suggestions, that can make this process easier, comment down bellow. I’m using Inkscape, an open source vector graphics editor, that is used for image editing. Also, for a long time I wanted to try Linux distribution called Manjaro, so this G code generation is done using this operating system. “G-code (also RS-274), which has many variants, is the common name for the most widely used numerical control (NC) programming language. It is used mainly in computer-aided manufacturing to control automated machine tools. The “how” is defined by g-code instructions provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow.” G-code is a language in which people tell computerized machine tools how to make something. Now when we have basic understanding of G code, let’s install Inkscapeon Manjoro. Open the terminal in Manjaro with keyboard shortcut Ctrl+Alt+Tor by pressing F12 if program Yakuakeis running in background.
