FAILED RepRap PCB Routing

thingiverse

I did end up with a working PCB, but it took too long and was only just useable, I have gone back to Ferric Chloride. Instructions I bought a PCB Drill from RS, part number 547-616 I fitted it to my printer, wired to hot end supply (so I could control it). I was using Eagle 6.3.0 Light I haven't played with this since July 2013, so all this is from memory, hope it helps. CarV2 was the Eagle project I was using (basically a car voltage meter, inside zip) ulp is the directory containg the code inside ulp is pcb-gcode-3.5.2.11.zip containing original see ulp\docs\readme.html Originally I modified the ulp source, that version is in MyOld. I cannot remember if I modified the current ulp. I definately created profiles\MetricPrusa.pp (choose GCode Style tab in PCB-GCODE and pick RepRap Metric Prusa) I used double sided carpet tape to stick the PCB material to bed. I only had shears to cut PCB, so was not flat enough. A pain to mill with enough accuracy to mill copper without milling fibreglass. I used 30 degree engravers bits, wore out one bit per PCB. Maybe the drill was too light, maybe the drill was too slow. Took a morning to route a 2" x 1" PCB. Photos are of failed PCBs, I never took photos of final working unit and I have no idea what I have done with it. Gave up and went back to good old ferric chloride.
