TRAK LPM Programming, Safety, & Operating Manual 
A Conrad is added between an arc and a line. 
5.11 Memory and Storage 
Computers can hold information in two ways. Information can be in current memory or 
in storage. Current memory (also known as RAM) is where the ProtoTRAK PMX CNC 
holds the operating system and any part program that is ready to run. While a program is 
being written, it is in current memory. 
For the ProtoTRAK PMX CNC, storage of programs is on a USB thumb drive or on a 
networked drive. We strongly recommend you habitually back up programs. 
5.12 Current and Staged Views 
Current refers to a program or operation that is being done at the present moment on the 
TRAK LPM. Staged refers to a program or operation that you intend to put on the 
machine in the future. The ProtoTRAK PMX allows you to toggle back and forth 
between these two states so that you can use labor better. Rather than have an operator 
stand and watch a (current) job running, he can use the staged view of ProtoTRAK PMX 
to do almost all the set up work for future jobs.
