I’ve just open the Gcode that I’ve just exported from Inkscape using the J Tech plugin. So the laser is about 40mm above this board. Ok I’m going to try cut a tool path using the laser this is the PLH3-6W laser from Opt Laser, and it looks pretty cool. I can’t remember now but that looks like it’s to scale and in the position I expected it. If I open the gcode you can see it’s at the right scale for my wasteboard which is roughly 32cm across and this should be 12-14cm across. If I press apply it’s created a visualisation of the Gcode around that. My CNC machine the power setting is actually in relation to the RPM speed of the spindle so the max power is actually 24000 as opposed to 255 of 12000.Īlso I am using GRBL 1.1 so I can use, well there’s a few things I should add to the code to make cutting a little bit safer but essentially even generating this will work.
I’m going to go into this a little bit more. And it’s simply a matter of going to the plugin, adjusting these so they are at the right settings. My origin position is actually the top right point of the CNC machine, so I’d have to position the DXF file off the canvas before generating the Gcode. So don’t press open – press import, and find your file and that’s an example. If you open the DXF file you will have scaling issues when you then go to export the Gcode. And then you’ve got the J Tech Photonics Laser Tool there.Īnd the secret to using this is simply importing your DXF and not opening them.
So if I open Inkscape now, and you’ll find the new Plugin under extensions and Generate Laser Gcode. And then I’m going to go to the C Drive, programme files, inkscape, share, and extensions and I’m going to paste into this folder. And then you want to copy the laser Python file and the XML file. So once you’ve downloaded the appropriate version of Inkscape for your computer and the Zip file with the J Tech plugin, you want to make sure you install this onto your computer and then extract the Zip file. Ok I’m going to show you how to install Inkscape 0.92 and then add the J Tech Plugin which will allow you to create Gcode to cut DXF vector files. It’s particular important for me as I’m use a dual spindle / laser controller. This is the header and footer code you can add to the exported Gcode for use with machines using GRBL v1.1.
