Basic Information ----------------- The cutting area is: - 600 x 400 mm (A2 Landscape) for the Orange Laser - You can cut material up to around 6mm thick - Some people (everyone bar Bob) have been having problems with red and black. If you're trying to do something intricate such as engraving we recommend NOT using black ANYWHERE on your design to avoid bits being engraved unnecessarily and wasting your time/money or potentially wrecking your design. Inkscape -------- ### Suggested Page Layout - I like to use a 200mm x 300mm page, set to millimetres, with a 1mm grid. - [Laser_Template.svg](http://wiki.hacman.org.uk/images/b/bc/Laser_Template.svg) Is a good template. Just put it in the templates directory in your inkscape folder to use it. Templates Directory: - Linux: .config/inkscape/templates/ - Windows: %APPDATA%\\Inkscape\\templates\\ Templates: - Orange Laser template: [Media:Laser_Template_Orange.svg](Media:Laser_Template_Orange.svg "wikilink") ### Different Cuts / Colours Each different colour, line thickness, layer and group can be selected to cut differently, and the cut order changed. It can help to use solid background colours in your inkscape designs to denote what should be cut and when ### Designing the cut First make an object to cut using Inkscape Notes - When creating an image to cut it needs to be all lines or all fill - Make sure any lines are not dotted lines and are single fill lines - You should not use a mixture of both, or the laser cutter may throw a hissy fit - The thing you're engraving should be surrounded by a box or shape to cut it out as the final step - The cut lines and engraving lines should be different colours (each type of laser strength should have a different colour) Solidworks ---------- If you're importing a design from Solidworks the best way to do it is to export the model to a DXF file first - Open up the 3D model within Solidworks - Select File -> Save As - Select DXF in the drop-down filetype list and click Save - At this point some options will be visible on the left-hand side which you need to set before the actual save is done - In the Views to Export, untick Current, and tick Top - The other options such as Alignment can be left as defaults - Next make sure the view is a direct top down view, with the X / Y / Z cross at the bottom left, click it to make sure the view is aligned - Click the tick button - A preview will be visible of the outputted diagram before it is saved - Import the DWF file into Inkscape - When prompted make sure to untick the option to scale the image to A4, to make sure the measurements are accurate Visicut ------- ### Importing the Design into Visicut Next you need to import the design from Inkscape to Visicut - Within Inkscape select **Extensions -> Lasercut Path -> Add to Visicut** - place the design towards the bottom left-hand corner as it's more accurate there and this is where the zero point is - Try not to go within the last 5mm of the edges. The small edge stop within the cutter will align the part as such If the Visicut extension doesn't work for any reason, save the design as an SVG, and reload directly into Visicut. Note: any text needs to be converted into paths first ### Types of Cut There are several types of laser strength / profile Marking is a very light form of engraving | Type of Cut | Description | |------------------|----------------------------------------------------| | Ignore | Ignore the layer in the diagram | | Mark Shallow | Mark Shallow | | Mark Deep | Mark Deep | | Engrave Dithered | Engrave Dithered - darker colour equals deeper cut | | Engrave Solid | Engrave Solid | | Cut | Cut all the way through the material | ### Setting the layer profiles Next you need to map each layer in the design to a cut profile (Laser speed / strength) - Select the material (e.g. Acrylic) - Select the material thickness (e.g. 3mm) - Under the Mapping tab, select **Map by Fill Colour** - Use the shift key in Visicut to view overlaps Next re-arrange the layers and select the type of cut - Place layers with engraving at the top of the list - Place layers for cutting holes in the middle of the list - Place the final cut stage as the last in the list - make sure all layers needed are ticked It's best to cut the outer line/edge last, because the piece is more likely to move after doing so, making any subsequent cuts inaccurate. So make sure to do this stage last. ### Laser Settings Next you need to make sure the settings under the laser settings tab are sane / correct For Acrylic:
