drill files, viewmate

I'm trying to generate a CAM output and preview it before submitting to PCB

manufacturer. I read the recommended Al Williams book.

 

I'm using ViewMate to preview the files.

 

All the layers are OK, except the drills.

 

I found this topic that seems to solve the issue (haven't tried):

It seems that the problem are the leading zeros that ViewMate needs.

 

But I'm confused, the point of previewing the files is to ensure that the

manufacturer will understand them. Maybe if I change the .def file the

manufacturer will have problems ?

 

So my questions are:

 

What format should I use to generate/preview the drills to avoid problems ?

Could you please point me to a tutorial about excellon files ?

Usually the EXCELLON device is readable by all manufacturers.

You could add a further EXCELLON device as mentioned in the

message you linked to so that it fits to Viewmate.

I'ld recommend to use the following definition for EXCELLON. It has

a better init sequence that should work with all viewers and

manufacturers. Simply try it with Viewmate as well.......

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"
