Hi all, haven't posted in a while. I've gotten some free time and so getting back into the EE hobby. I just bought a 6040 CNC: http://www.omiocnc.com/x6-1500gt/ (well, a slightly cheaper clone of it). The resolution on this thing is supposed to be excellent. Can't wait to start routing some PCBs. - Anyone have any starting advice? - Anyone know of a good source for FR-1 copper boards? I have some FR-4, but I don't want to create fiberglass dust. - What are some good bit sizes to get for routing small surface mount component pads? --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
