GENERAL   Procedures   for   PCB   Printing   from   Eagle   CAD   files
(UBC   Engineering   Physics   Project   Lab,   Tinny   Lai,   2008   Sept)
Exporting   CAM   files   from   Eagle   CAD
1.
Select   File   >   CAM   Processor.
2.
Inside   the   CAM   Processor   Window,   select   File   >   Open   >   Job…
3.
Open   the   gerb274x.cam
file.
4.
Under   the   “Component   Side”   tab,   make   sure   the   “Top”,   “Pads”,   and   “Vias”   layers   are   selected.
This   will   be   generating   the   .cmp
file.
5.
Under   the   “Solder   Side”   tab,   make   sure   the   “Bottom”,   “Pads,   and   “Vias”   layers   are   selected   and   that   the   “Mirror”   checkbox   under   Style   is   NOT   checked.
This   will   be   generating   the   .sol
file.
6.
If   there   is   not   a   tab   for   “Board   Outline”,   click   the   “Add”   button   while   on   the   components   or   solder   tabs   to   create   a   copy.
Rename   the   section   to   “Board   Outline”   and   the   file   extension   to
.otl.
Deselect   all   the   layers   except   the   “Dimensions”   layer.
This   will   be   generating   the   .otl
file.
7.
Click   “Process   Job”   and   these   3   files   should   be   generated   in   your   project   directory.
8.
Select   File   >   Open   >   Job…
9.
Open   the   excellon.cam
file.
10.
Make   sure   that   the   “Drills”   and   “Holes”   layers   are   selected.
This   will   generate   the   .drd
drill   data   file.
11.
Close   the   CAM   Processor   window.
12.
Type   run   drillcfg   on   the   Eagle   command   line.
13.
Select   mm   and   save   the   .drl
to   you   target   directory.
14.
Transfer   these   files   to   the   Milling   Machine   computer:   .cmp,   .sol,   .otl,   .drd,   .drl
Importing   Eagle   CAD   files   into   Circuit   CAM   to   generate   a   LMD   file   for   BoardMaster
1.
In   Circuit   CAM,   select   File   >   New   >   eagle.cad
2.
Click   the   “Import”   button   and   select   the   .cmp,   .sol,   .otl,   .drl
files.
3.
Select   File   >   Import...
or   click   the   import   button.
4.
The   Import   window   will   come   up   for   each   of   the   files   selected.
5.
For   the   .drl
file,   change   the   Aperture/Tool   template   to   "Eagle_Excellon.txt
(NCDrill)"   and   click
“Import”.
6.
For   the   .cmp
file,   change   the   Aperture/Tool   template   to   "TopLayer"   and   click   “Import”.
7.
For   the   .sol
file,   change   the   Aperture/Tool   template   to   "BottomLayer"   and   click   “Import”.
8.
For   the   .otl
file,   change   the   Aperture/Tool   template   to   "BoardOutline"   and   click   “Import”.
9.
For   the   .drd
file,
10.
7.
Select   Edit   >   Contour   Routing...
and   click   “Run”.
11.
Select   Insert   >   Rubout   Area   and   add   select   the   layers   and   areas   that   you   want   to   rub   out   the   copper.

12.
Select   Edit   >   Insulate.
Select   the   width   of   your   choice   and   click   “Run”   for   both   the   Top   and
Bottom   Layer.
13.
Select   File   >   Export   >   LPKF   >   LPKFCircuitBoardPlotter   to   export   the   .LMD
file   to   be   used   in   Board
Master.
Importing   a   LMD   file   in   BoardMaster
1.
In   BoardMaster,   select   File   >   Import   >   LMD/LPR...
to   import   your   .LMD
file.
2.
Click   the   button   with   an   arrow   point   in   each   of   the   4   direction   and   pick   a   place   on   the   machine   area   that   will   fit   your   PCB.
The   machine   head   will   move   to   this   position.
The   individual   arrow   buttons   can   also   be   used   to   make   the   machine   head   bit   by   bit.
3.
Find   the   button   with   two   rectangles   translated   diagonally   (Should   display   “Enables   the   moving   of   instance   of   project   by   mouse”   when   hovering   over   the   button).
Select   this   button   and   move   your   PCB   layout   to   the   machine   head   cursor.
4.
Go   through   the   following   phases   by   selecting   the   phase   on   the   top   left   area   of   the   window
(Should   initially   read   “1.
MarkingDrills”).
After   selecting   each   phase,   click   the   "All+"   button   on
the   top   right ‐ hand   side   area   and   click   “Start”.
a.
(1)   Marking   Drills   b.
(2)   DrillingPlated    c.
(5)   MillingBottom     *
At   this   point,   flip   the   cooper   board   over   the   x ‐ axis   before   proceeding.
d.
(7)   MillingTop     *   e.
(10)   CuttingOutside
Adjust   tool   height   everytime   a   tool   switch   happens.
