Information 
7.1 Programming Overview 
The ProtoTRAK PMX CNC makes programming easy by allowing you to program the 
actual part geometry as defined by the print. 
The basic strategy is to first fill in the initial program information in the Program Header 
screen and then program the features of the part by selecting the soft key event types 
(geometry) and then follow all instructions in the Data Input Line. 
When an event is selected, all the prompts that need to be input will be shown on the 
right side of the screen. The first prompt will be highlighted and also shown in the Data 
Input Line. Input the dimension or data requested and press INC SET or ABS SET. For 
X or Y dimension data it is very important to properly select INC SET or ABS SET. For 
all other data either SET will do. 
As data is being entered it will show in the Data Input Line. When SET, the data will be 
transferred to the list of prompts in the right side of the screen, and the next prompt will 
be shown in the Data Input Line. 
When all data for an event has been entered, the entire event will be shifted to the left 
side of the screen and the conversation line will ask you to select the next event. 
7.2 Enter Program Mode 
Press MODE, select PROGRAM soft key. 
The ProtoTRAK PMX CNC will allow one program in the Current view and one 
program in the Staged View. If there is already a program in the Current or Staged View, 
entering the Program mode will allow you to edit or add to that program.
