PCB isolation

Thu, 05 Jan 2017 15:32:49 GMT

Good day to all in this forum, I am very new to FlatCam program and I do need some basic direction just to start... I installed a FC version 8.5 on my PC. I did just that: no other things. I would like to isolate a PCB track starting from a gerber file . I am able to open it and i do see it on FC. The indication of the manual seem to be different wrt mine one. Could anyone help me by indicating the complete sequence of operation ( procedure ) to get the Gcode output file to my CNC please ? Thanks in advance for any help. Regards, Ambro

Export you gerber mirrored. Export your drill file mirrored. Load Gerber into Flatcam Load drill file into Flatcam. I like to adjust the offset at this point. Click on the gerber object that was loaded. Set tool width and number of passes Press generate geometry (this creates a iso objest). Note you may want to first check combine passes. Click on you Excellon object and set you various parameters. Click on Generate. This creates a CNC object for the drills. Click on your iso object for the traces. Set your various parameters and press Generate. This creates a CNC object for the traces. Click on the cnc object for the traces. Press Export gcode Click on the cnc object for the drills. Press Export gcode. Flatcam is very non intuitive imho. But far, far easier than trying to load your drawing into Eagle to use pcbcode, if you don't use Eagle. And Flatcam is eaier to user than Coppercam imho.

And once you get used to all of the steps, FlatCam is actually very easy to use.

You need to open the object in question. Scroll down to Offset. Manually enter your coordinates. A negative number moves down or to the left, a positive number moves up or to the right. If you export your gerber and drill file correctly, it should be pretty close to begin with. You should set you origin to the lower left, if your design software has that feature. Diptrace does.
