Embedded Files
In Flatcam open the gerber file for your circuit board.
Under Project select the .gbr file.
In the Selected tab set up your parameters:
Tool dia. (I used 1mm)
Width (# passes): 1
Pass overlap (doesn't matter since we are using just 1 pass)
Click Generate Geometry. The plot on the right should show unbroken tool paths around all your traces.
Back in the Project tab choose your _iso.
Back in Selected:
Cut Z: -0.002 (.001 might work. It depends on how flat and even your board is under the cnc router.
Travel Z: 2 (The default 0.1 is too close)
Feed Rate 75 (slower if you use a smaller cutter)
Tool dia. 1
Spindle Speed 20000 (make sure motor is going as fast as possible)
Click on Generate.
Back in the Project tab select the _cnc file and then switch back to the Selected tab.
Change the Tool dia. to 1 and update the plot.
Click on Export G_Code. Save your file somewhere easy to find with a .nc or .tap file extension.
You can use ncviewer.com to double check your tool paths and G code.
