5.2 The LPKF ProtoMat 93s Commands
5.2.1 Command structure
The SMCU (Signal Processor Control Unit) control unit of the machine interprets
the HP-GL commands described below and converts them into set reactions.
The
resolution of the machine is 0.0079375mm
. This is a different resolution than
that of standard HP-GL-plotters. Therefore the output is scaled down when
original commands are used.
The syntax:
Symbol Meaning
{...}
The contents can be repeated any number of times.
()
The command parameters are between these brackets.
[]
The content of these brackets is optional and does not have to be
included.
The SMCU expects a separator between the command parameters which is not
any of the figures or upper case letters. A new command can follow a parameter
without a separator. The last character in a command file which is sent must be a
semicolon or a line feed symbol (0A hex.).
Unknown commands are ignored by the control unit, but their parameters can lead
to unwanted plot absolute or plot relative commands.
5.2.2 HP-GL standard commands
AA (x,y,a{,ß}){;}
Arc Absolute
Draws an arc around the absolute coordinate (x,y) starting from the current
position with the arc angle a=[degree]. With a negative arc angle a, it is drawn
clockwise, but otherwise counterclockwise.
AR(x,y,a{,ß}){;}
Arc Relative
Draws an arc around the relative coordinate (x,y) starting from the current position
with the arc angle a=[degree]. With a negative arc angle a, it is drawn clockwise,
but otherwise counterclockwise.
CI (r{,ß}){;}
Circle
Draws a complete circle around the current position with radius r. Resolution ß is
ignored as the maximum resolution is always used when drawing.
