TRAK LPM Programming, Safety, & Operating Manual
When you use the graphics to guess dimensions on arcs, you may load in guesses for both
the X/Y End and the X/Y Center before leaving the LOOK screen.
When you have not first pressed the Guess key, pressing LOOK gives you the same
screen as in regular programming. Whether you enter the guesses as key presses or by
using the graphics, the drawing of the LOOK screen distinguishes between events that are
fully defined and those that rely on guessed data. OK events are represented by solid
lines. NOT OK events are represented by dashed lines.
9.9 Calculated Data
Prompts that are skipped or for which guesses are entered may be replaced by data
calculated by the ProtoTRAK PMX CNC. Calculated data is shown in red in order to
distinguish it from the data that you entered. You cannot edit calculated data, but you
may edit your original input. By putting the event with the calculated data on the right
side of the screen, you may position the cursor to the prompt and re-input the data.
9.10 Arcs and Conrads
If the print is missing a lot of data, it may be desirable to program arcs as separate events
where possible. If you know the center and radius of an arc, program it as an arc rather
than using the Conrad. This gives the system more information to work with in figuring
out other missing points.
