After that the G-Code will be stored and the laser path will be outlined.Ath the end it will move up to the start height. If you have more than one path, the laser will move down Path Depth (mm) between passes. Click Extensions Generate G-Code for Repetier Repetier Laser Tool… to start our plugin.The Plugin will use this path to generate the G-Code. Click Path Object to Path or press Shift + Ctrl + C to convert the text into a path. Only marked objects will be used to generate the G-Code. If you have more objects (lines, circles, …) to embed in your G-Code, you have to mark them all. The bottom left corner is the 0,0 location of your machine. You will find the plugin at Extensions Generate G-Code for Repetier Repetier Laser Tool…. After starting Inkscape, the plugin is installed. Then download our Repetier G-Code Plugin for Inkscape ( up to version 0.91, as of version 0.92) and copy the content to inkscape\share\extensions. Specifically, when using the GrblControl control program, it is recommended to add the line “G0 X0 Y0 Z0” to the beginning of the G-code.In this tutorial you will see how to convert the contours of text and images in Inkscape to G-Code to use it with Repetier-Firmware for CNC laser engraver. To avoid this, replace the command G0 with G1 IV. b) Some machine control programs can turn off the laser on the G0 command (100% not taken into account, just an assumption, because I came across a G-code where exactly such work was meant). Since this command is used to idle, the following are possible: a) The passage will be carried out at a speed of idle, not working speed. The plugin can use the G0 command to work on straight segments. To set a higher speed, you will need to replace the F750 parameter with the F1750. The maximum stroke speed in the plug-in can be limited to 1000. Depending on the machine, it may be necessary to replace parameter S255 with S1000. If the laser power is specified in%, a G-code can be generated indicating the power 0-255 where 255 corresponds to 100%. All replacements are for example purposes only. Download the following Rotrics G-code extension for Inkscape V0. Perhaps the necessary changes to the G-code (depending on the version of the plugin) We use the notepad and the quick change command “Ctrl + H”. File Name 25.adding a numerical suffix to the file name (it is convenient that you do not overwrite the name each time, the number at the end of the file name simply increases) 26. Lowering the laser along the Z axis after each pass – 0 (not used in this case) 23. The delay before movement after turning on the laser is 0 (it makes sense when milling) 21.Number of passes – 1 22. Laser power – 1000 (depending on the version of the plug-in, it can be indicated in% or specific numbers) 20. The speed of movement with the laser on (stroke) – 750 (depending on the material) 19. The speed of movement with the laser off (idling) – 2500 (depending on the particular machine) 18. Laser turn-on command – M03 16.Laser off command – M05 17. Open the G-code plugin (Menu “Extensions-> Generate Laser Gcode-> J Tech Photonics Laser Tool …”)ġ5. Set the width and height of the layer 200mmġ4. Check that the option to save aspect ratio is disabled (Since the drawing was drawn and circled in manually, slight deviations from the size 200x200mm, which should be) are possible 13. Choose a measurement of the size of the layer in mm 12. Set the initial coordinates of the layer x = 0, y = 0 11. Click “OK” and close the “Trace Bitmap” windowġ0. Select the layer with LMB fill and open the image vectorization window (Menu “Path-> Trace Bitmap …”)Ĩ. select LMB layer with the original image and delete it (Menu “Edit-> Delete”)ħ. Clamp on the flooded area of LMC and drag one of the layers to the sideĦ. Use the “Select and transform objects” tool 5. If the outline of the stroke is thin, you can set it to 0)Ĥ. The parameter “Grow / shrink” – 2px (increases the flooded area along the contour by 2 pixels. With a larger value can fill the entire picture through the contour) 3. With a lower value, gray spots may appear in the flooded area, which, due to the color difference, are not flooded. The parameter “Threshold” – 25 (determines the difference between the selected pixel and the neighboring ones that fall into the fill. Ideally, if the final pattern is monochrome (or b / w).ġ. If the picture is translated by scanning / photographing, it is recommended to circle the outline with a black pen, a thin marker, or something similar. In addition to the circuit, there should be nothing superfluous. The drawing should have a clear continuous contour. Everything you need for your laser module, laser cutting and laser engraving.
