You can generate a Gerber file out of your EDA of choice with the serial number. You'll have to put the data on a mechanical layer so you'll get a Gerber file only with the serial number and no other data. After that you'll load this gerber file into FlatCAM with specal option -follow 1 and use what is written here: http://caram.cl/software/flatcam/tracing-the-silkscreen-with-flatcam/
If I'm understanding correctly each serial number/gcode would have to be generated manually?
Yes, you generate the serial number with the Gerber files. Reading the link you provided I understand now what you want but I don't know how easy (or hard) will be to create a FlatCAM tool like that. Actually, creating a geometry out of a font file needs to be researched first.
I think I may have found a starting point for what I want to be able to do. https://github.com/LinuxCNC/simple-gcode-generators/tree/master/engrave I just need to figure out how to add the sequential numbering output and input fields similar to the previous link.
In any case, adding text in Geometry Editor is missing. I will see what can be done to add text capability but it will be isolated text therefore positive image (text will be made out of copper) as opposite when loading a Gerber file with follow parameter when the text is negative (meaning lack of copper where the text is). Also internal holes like in a 'e' lower case letter might not be cleared depending on the font size and tool size.
hi i'm having some scaling issues when importing gerber files from Altium
@lasalmaldeniya you should make your own topic with the question. After that post what version of Altium (Designer, CircuitStudio, CircuitMaker) you are using, what version of FlatCAM you are using, what operating system (eg Windows 7 x64, Ubuntu 64bit etc). It will help if you add a link with the Gerber file that has issues. Although I think that more likely you have problem with Excellon files (NC-drills) not with the Gerber itself, but who knows? BTW, I also use Altium and had no issue whatsoever with FLatCAM, be it FlatCAM 8.5 official or the Nightly installer that I post from time to time.
