There are a large number of other possible header commands but they are almost all related to the control the machine and have no effect on the actual layout data that one is trying to extract from the drill file in the software world. It stops the machine and tells it to wait for a command to continue. This feature can be used to identify a company or product, supply a part number etc. The M97 and M98 commands allow you to program the CNC-7 to write a message on the board. It is possible to drill a series of holes that spell out words or numbers. An X and/or Y coordinate must be used to define the spacing between hole centers. The number following the R specifies the number of repeats. This command drills a series of equally spaced holes from the previously specified hole. Data that follows will be drill and/or route commands. There are additional parameters but if you are a PCB designer it is not up to you to specify feed rates and such.Д®nd of the header. For each tool used in the data the diameter should be defined here. Use Format 2 commands alternative would be FMAT,1Дefines tool 01 as having a diameter of 0.020 inch. This is very rare nowadays if not present assume the coordinates are absolute. Incremental input of program coordinates. If the trailing zeros are included then the command would be INCH,TZ. If the data is in millimeters then the command would be METRIC,LZ. The reading software needs to know both the units and where to re-insert the decimal point therefore one must have either leading or trailing zeros or a decimal point in the coordinate data. (This implies that the trailing zeros are suppressed. This actually has two pieces of information INCH indicates that coordinates that follow are in inches and LZ indicates that the leading zeros in the coordinate data are included. should always be the first line in the header Here are the most common header commands along with their function and use by the reading software: While in principle the header is optional, one should never write a drill file without a header. This contains general information about the job and the data to follow.

However we have noticed that many PCB layout tools do not take full advantage of the header information which makes reading the drill file more difficult than it should be.ДЄt the beginning of the file, the first few lines are typically a header. Because of Excellon's long history and dominance of the PCB drilling business for many years their format is a defacto industry standard.ДЄlmost every PCB layout software can produce this format. The Excellon drill format is a subset of RS274D and is used by the drilling and routing machines made by the Excellon corporation.
