First set the data you want to append to an unused layer in KiCad so it is easy to tell apart. Then export with the “Plot” function and open both gerber files. Copy the data area shown in the below image into the file you want as the master. The aperture will most likely conflict… Continue reading Gerber PCB File Merge Multiple File Items Together Using Text Editor – KiCad

Use the “Combine” tool under the Modify section to subtract or add solid bodies together. If you want to re-orient “derived” parts you must do it by creating an assembly and orienting the part in there, then deriving the assembly, not the original part.
These are what I use on my retrofit 30W Chinese machine, they are probably not directly portable to any other machine because of so many variables in these things, tube life etc.. I have the analog current limit set to 15mA for 100% power but don’t know how accurate the little meter is. One other… Continue reading Lasercad Laser Cutter power settings – 30W CO2
This is just a very brief note, mostly for my personal reference.. Tutorial: http://northernhope.blogspot.com/2013/05/stl-to-step-with-freecad.html Some additions to the above tutorial: Part > Convert To Solid before exporting Upon opening in autodesk inventor the part will be solid and you can modify faces and create sketches upon them, much better than the native STL import in autodesk.
The dudes head is magical as well. The EQ part is what works the best.. cut out everything below 300hz for voice stuff if you have bad hum and can handle the loss of lows.
First on the left panel in the “Origin” section turn ON Visibility for the XY Plane. Now select the first sketch/piece of your model that dictates the rest of its orientation, usually the topmost piece. Then click “redefine” from the context menu, select the now visible XY plane.. Done.
