5.3 Operating FAQ
Q: How do you continue operation after a cutting stoppage during automatic cutting?
A: The following functions can be used after cutting is stopped in the automatic mode:
1) 【STOP】 key: The system will stop. The program can be continued immediately by pressing
【START】 key. If necessary, use the arrow keys【↑】【↓】【←】【→】to adjust the torch
position. When the torch is located at required position, please press the 【START】 key to
continue cutting.
2) Use the【F↑】【F↓】keys to adjust the speed up or down, by 1% for each button press.
3) Use the【S↑】【S↓】keys to move the torch up or down.
Q: How do you re-start a cut if the plate did not pierce?
A: The machine can be sent back to the origin if this happens.
Press the 【STOP】 key to stop machine motion, then press the【F6】key to move backwards on
path. The torch will move backwards on path until it reaches the pierce point. You may then re-start
the cutting process and press the 【START】 key to begin cutting again.
Q: If the power is lost during cutting, or some other interruption causes the program to be
abandoned, can the un-finished program be recovered?
A: Yes, the operator can use RESUME function to finish cutting a parked program:
1) If the program has been stopped and abandoned manually, follow the procedures in section
4.16, Resuming Parked Programs.
2) If there is a loss of power while cutting, the program can easily be recovered as long as
the machine is not moved while power is off. Follow the procedures in section 4.16,
Resuming Parked Programs, but be sure to select the option 3) RELOCATE PATH, so that the
program will continue from the current machine position.
Q: Why can some part program files not be read by the CNC after they are copied to the USB
disk using Windows Explorer?
A: If using the file type extension “.MPG”, Windows can include meta-data in the file or on the disk. It is
suggested that files only use the file type extensions “.CNC”, “.NC”, or “.TXT” in order to avoid
problems.
Q: Why does the machine lock-up when reading the USB disk?
A
If the USB disk checks out OK, there may be two reasons:
1) There may be system or hidden files on the USB disk that the CNC is attempting to read.
Some system files will cause the CNC to repeatedly attempt to read a file which cannot be
understood by the CNC, so it appears to be locked up. It is suggested that the USB disk be
freshly re-formatted, and only the necessary part programs be stored on it.
2) Inspect the USB socket to see if it may be loose, or if it may have become fouled with dirt or
soot.
Caution
If it becomes necessary to remove the machine’s cover during
troubleshooting, refer all work to a qualified service technician.
