FreeCAD engraving toolpath and CNC machining

- Hello Internet,
in this video I show the preparation of some engraving jobs using FreeCad. For demonstration, I mill some text and a small svg graphic onto a workpiece using a Genmitsu 4030 CNC and compare two different router bits. The goal is to show you the basic workflow you can follow in your own projects and understand the different options in relation to the font type, for example, standard true type font and single line /or stroke fonts. We will have a look at the different working steps to prepare the job for CNC milling.
So much in advance, it didn't work right away, but in the end there are usually solutions for all problems. So let's get started.
I presented my personal CNC setup, modeling, and machining approach in some additional videos. This includes the setup and use of the different components, my modeling and machining process, and my selection of software and hardware tools.

Thank you so much for taking time to show us how to do this. I wish I had found this video first. Thank you again!
Dude you are awesome! I just found out that the reason I couldn't get my CNC to work properly was because when I was extruding it I wasn't checking the reverse box. Thank you so much!
Thank you
There is a VCarve option under the engrave operation and I'm able to select it but can't make it work. It would be amazing if you would create a video showing how to use it.
I like this. I have been trying to work out how to sensibly add colour infill for ages. Your formply substrate answers the question. Coat 5he surface prior to machining then spray colour and remove the coating. I realise that sounds vague, acrylic paint should do the trick allowing simple peeling.
Thank you 👍
Thank you for this.
Hi Win, here is a starting point www.imajeenyus.com/computer/20150110_single_line_fonts/index.shtml
I noticed you did not use any of the included clamps to hold down the wood piece. Why?
Thank you for the video! I was wondering, which file type is required when selecting the font type? It seems that the font files are not in the FreeCad files? Can I donwload them from the FreeCad website?
Your assistance would be much appreciated. Thank you in advance.
Hi Win here is a starting point...www.imajeenyus.com/computer/20150110_single_line_fonts/index.shtml
Look for single line fonts, but many search results are directing to commercial offers. There are some free font that I used in the video and I collected them over some time.
Hi! Great video! But I have a problem, when I create the job and select the grbl post processor, the error message: "The job was created without fixture support" appears. Any idea why this happens or how to fix it? Thank you very much!
Hi did you change the default settings for the measurement. Check the documenation there is a good diagramm displaying the measurements. I also referenced it in the video.wiki.freecadweb.org/File:Path-DepthsAndHeights.gif
Kann man für das Gravieren eine Skizze vom Sketcher nehmen?
Hi, die Skizze markieren und einen Engraving Job auswählen.
@@umlooad Danke. Wir würde das funktionieren, wenn ich etwas ausschneiden und eine Außen- oder Innenkontur auswählen möchte?
@@stefankrimbacher7917 Hallo Stefan, willst du einen Cutter einsetzen? Es ist sehr schwierig zu sagen was die beste Lösung ist, mit so wenig Informationen. Du kannst 2D Zeichnungen nehmen und die Pfade damit generieren lassen (Draft Workbench).
@@umlooad Okay. Mit der Funktion Profile funktioniert das, jetzt habe ich es endlich. Man kann eine Innen- bzw. Außenbearbeitung und einen Offset einstellen.
Can you make a video about creating 3d milling toolpath?
Hi, I´m currently using Fusion 360 for 3D milling, after testing freecad 3D options a lot. There are many problems with Freecad 3D milling toolpath generation currently, therefore I used Fusion. A video is in progress and comes out in the next days. Do you have specific questions?
@@umlooad yes, I have some problems with creating a toolpath for 3d milling
