Then: Next Extensions => Gcodetools => Orientation points. You also need to add Gcode before path = M3 (start your tool spindle)Īnd Gcode after path = M5 (stop your tool spindle) to activate your cutter. Step say 0.25mm each increment step to reduce risk of cutting too deep, each PASS) (This 'Z"-axis setting will be dealt with later) Penetration (depth of cut mm) as required. Select the Text tool on the left and click on and change: I found that the only tool in the list that works for me is the Default one at the top.Ī grey box parameter appears by your document. Slide the other smaller one, the bitmap back onto the document in the correct place.Įxtensions => Gcodetools => Tools library. Slide the top one to one side so you can see both and then select and delete the larger one. One is on top of the other so you can only see one of them. This adds a new object to the document, the original image plus a bitmap version of it. Next: select the image in the document and go to (double-click the image to allow the corners to be used for rotating say about 30%) Go to File => Import xxxxxx.jpg as a linked file not embedded withĪnd shift the image nice and tightly inside the Document Properties frame. (after we rotate the logo about 30 degrees) With Border Shadow Unticked so the image will just fit it with a bit left over. Ie: /spare/woodwork/CNC_Laser_Router_3018_PRO_Gary/Gary_CNC_projects/Frank_Cheeseman/Īnd change size to say: 60m(W) "X" x 60mm (H) "Y" Then rotated 45 degrees and saved to a folder/file say: Use Libre Writer with FONT: "URW Chancery L" 72 Font Size exported as: JPG Job Example: engraving "Frank Cheeseman" onto an Acacia timber cheese platter.

Inkscape is used to import the JPG image and process it in readiness for G-COde, saved as. LibreOffice Writer can be used to prepare a desired TEXT, saved as a. Two programs are needed, running on say: Linux Mint v21.ġ. This article shows how to use free software tools linking a PC to a CNC 3018PRO hobby unit to produce engraving. Gary's limited experience in this area has nonetheless been a real fun exercise of learning how to make cheeseboards with family names engraved thereon, and the fixed depth coding was staraight forward. This is a totally different scenario to engraving a complex graphics image (like the KDWC Club Logo) where there needs to be layers, with each layer having deeper cuts that others, to give a depth of field feeling. It is time to show how to use this machine's ENGRAVING facilities for fixed depth cutting operations.įixed Depth, is mentioned specifically, because most TEXT ENGRAVING simply involves cutting each character to a fixed depth (say 1.5mm deep) into the job for instance. Gary Pope, Life Member of KDWC, has been documenting the use of his CNC 3018PRO Laser/Router unit in recent Ingrained Newsletter articles. I'm guessing this is something silly that I don't understand, any help would be appreciated.CNC coding for Engraving a fixed depth cutting project. Worth noting that this also happens if I draw a shape using Inkscape's built in tools instead of importing an SVG. I also tried using Stroke to Path instead of Object to Path, which creates an outline of the line instead of a single line but also doubles the tool path. I've experimented with changing the stroke width which doesn't help.
