BUG-O Systems Programmable Gantry System - Manual (Page 6)

INTRODUCTION
This is a 2-axis gantry that has 2 synchronized drives running on parallel tracks, and a second axis drive carrying a
cutting torch that runs on a cross beam. It can be used for flame or plasma cutting, or welding, of a variety of shapes
programmed and stored in memory.
PROGRAM CONTROL DESCRIPTION
The machine has 20 storage areas in memory for different programmed shapes, numbered 0 to 19. At any time, one of
these shape numbers is the current one, and will stay current even when power is shut off and turned back on, until the
shape number is changed by the operator.
All programming is done with the hand-held terminal provided; this may be plugged into the connector on the rear of the
machine or unplugged at any time. The terminal is not needed to run the machine once programmed; it is recommended
it be disconnected when cutting.
Shapes are built up only from the segments provided: circular arcs and straight lines, square or inclined, by selecting
type and quadrant for each segment. A shape can have up to 50 segments. Some other operations, like solenoid On/
Off, time delay, or repeat another shape a number of times, also count as one segment each if used.
OPERATION
When first plugged in, the position of the machine becomes the reference Start (Home) position. Now there are 3
options (the pendant terminal is not needed for the first two).
1. MOVE
To change the Start position, push and release the STOP/PAUSE button, move the machine manually to the
required position using the manual X and Y jog switches, and push the RESET button.
2. RUN
Push the RUN button to cut a shape.
3. PROGRAM using the Hand Held Terminal
The Programming operation is selected by pressing keys A, B, C, D, E.
A: ALL SEGMENTS; data entry for new shape consists of Total number of segments
Data for each: Type (arc, x/y line or slope)
Quadrant 1-4
Size (radius, or x/y dimension) See Shape programming for details.
The data should be tabulated on paper from a diagram before entering.
B: PROGRAM SEGMENT
Press B on terminal to re-program a single segment. This is useful if there is an error in data for just one
segment, so the whole shape does not have to be re-entered.
C: CHANGE Shape Number
Press C on terminal to change the current shape number. Enter the new shape number. The program
switches to the new number in memory, and to whatever shape is stored there.
For example, a 2 inch diameter circle could be 4 Segments:
1. 2 1 100 Counterclockwise arc quadrant 1 1.00 inch rad
2. 2 2 100 Counterclockwise arc quadrant 2 1.00 inch rad
3. 2 3 100 Counterclockwise arc quadrant 3 1.00 inch rad
4. 2 4 100 Counterclockwise arc quadrant 4 1.00 inch rad
