I posted this question in the Batch PCB forum but I wasn’t sure where to ask…so here is the question:
I am new at this so please bear with me. I designed a board with Eagle and sent it in for fab. The board came back fine but some of the silkscreen information on the top was missing. The component outlines were fine and the text I added was OK. What was missing is the component values and designations…I.E. R22, 450 ohms and other components. I think it may some option I left out when creating the CAM files. I just realized after looking at the gerbers they were missing. My fault for not looking closer before ordering but I still do not know what I left out or did wrong…Any info appreciated.
You hadn’t turned on layer 25 (tNames) and 27 (tValues) for your Top Silkscreen in the CAM processor, but are you sure you really want those turned on, especially tValues? Better to put everything you want as silkscreen on the tPlace layer (21). Or so they recommend in the Sparkfun Eagle turorial.

Thank you for the reply. At least that was all that I messed up...lol...I am learning Eagle but I am still on the lower part of the learning curve. The Layer 25 is probably what I should have turned on. The part name is almost a standard on the top silkscreen for the purposes of assembly. Does the DRU file that I loaded this time control the layer information? The reason I ask is the last boards I ordered I believe I used the default DRU file and this time I used the Sparkfun file. Perhaps that is why that layer (25) was not include?...Is there a "one size fits all" DRU file for simple designs?....thanks again.... :D

I use the Sparkfun file myself, but I have modified it to use metric instead of imperial since the board house I've used (Olimex) are using metric drills. This file only uses layer 20 (Dimension) and 21 (tPlace) for the top silkscreen. I just put the part names on layer 21 along with any other text or graphic I want silkscreened, like what a connector or LED is for. I will find out how good it works (for me) in a few weeks time when I get home. I sent off the files to have one panel (Eurocard size, 100x160mm) made last week and another one yesterday.
