Hi just joined and am a total Newbie to routers. I just ordered a 3018Pro MAX CNC. My interest is in routing printed circuit boards(PCBs). I have a lot to learn about Gerber, Gcode, etc. My biggest issues right now is I don't understand how the CNC control code takes into account the diameter of the bit being used or whether this has to be manually entered into the Gcode. Also, is there any product out there that will accept Gerber and Exelon(drill) files and automatically generate the Gcode to program the machine. It seems like a laborious process of converting files by third party tools and then loading them into a software tool such as ugsPlatform to actually operate the machine.
