  • Hello Richard, I am new to the software; Just started today with it. Have entered a schematics and have finished the pcb board. Without problems. Now I want to view the Gerbers in Viewmate. The copper traces from top and Bot look ok after export and import in Viewmate, but the drill holes not. I have tried several Devices, with different success. Best works the excellion but the scale is way of. Much to large in comparrisson with the copper traces. I tried to scale, but not good.

    Is thre a sequence written somewhere in the doc how I can best prepare the drl file for Gerbers; and that it is working for Viewmate?

     

    Thanks in advance,

    Hi Rob,

     

    I am pretty sure that the EXCELLON data you exported from EAGLE are correct. I suppose Viewmate does not exactly recognize the data format of the ecxellon data. It is 2.4 in inches.

    Could you check the settings in your gerber viewer? Maybe it is supposed to be 2.3, so it would result in a 10 times too big display.

     

    You could also test a slightly improved EXCELLON device definition. It states more about the data format in the header of the excellon file. Simply add the following section into the eagle.def file which is located in the eagle\bin folder. It is the definition file which contains all devices the CAM Processor offers.

     

    [EXCELLON_24]

     

    Type     = DrillStation
    Long     = "Excellon drill station"
    Init     = "M48\nINCH,LZ,00.0000\n"
    Reset    = "M30\n"
    ResX     = 10000
    ResY     = 10000
    ;Rack     = ""
    DrillSize  = "%sC%0.4f\n"        ; (Tool code, tool size)
    AutoDrill  = "T%02d"             ; (Tool number)
    FirstDrill = 1
    BeginData  = "%%\nM72\nG90\n"
    Units    = Inch
    Select   = "%s\n"                ; (Drill code)
    Drill    = "X%1.0fY%1.0f\n"      ; (x, y)
    Info     = "Drill File Info:\n"\
               "\n"\
               " Data Mode         : Absolute\n"\
               " Units             : 1/10000 Inch\n"\
               "\n"
