EXPLANATION
The Dl command designates an absolute direction, independent of the positions of P1 and P2.
The relationship between the two parameters, run and rise, designates a direction as shown in
Fig. Dl-1. Run and rise are values within - 128.0000 to +127.9999. Rise=0 designates a
horizontal direction, and run = 0 a vertical direction If both are zero, an error will result. For a
0 ,
known print angle
1 8 0 °
The Dl command with no parameters will default to the values "D I1,0;" (horizontal). If a single
or three or more parameters are used, the command will be ignored.
A direction set by the Dl command remains effective until a new Dl or DR command is executed
or the default values are enabled by the IN or DF command
