The trouble that you meet often and the solution ：

1 How are the FAST CAM programs uploaded to the machine?
Concerning FastCAM, the cutting drawings are made on a PC, using a CAD programme (which can saved as .dxf,as AUTOCAD by example) then using FastCAM loaded on the same PC translate in a cutting programme. This one is saves on a memory stick and loaded into Scihands via the USB port. Another way is, use FastCAM directly to make the drawings,then translate in a cutting programme with the G and M codes and to save it in the memory stick, then plug in the USB port of Scihands.

2 how does the programming work.
You made the drawing of the part to be cut with the provided FastCAM cutting software,After you setting the fastpath, this drawing is automatically translated in a cutting program. Or if you are using AutoCAD, you made the drawing with the CAD software, you process it with FastCAM to have a cutting program. As well, if you want to cut several time the same shape from the same metal sheet, the provided cutting software has the nesting facility.

3 After a long time cutting, the tip become very hot, what should i do to cool down it ?
Concerning the hot tip problem, the problem leading to self-extinguish the flame, can be observed, after two hours, the flame is becoming unstable and need adjustment of the flow of the cutting oxygen. To cool down the nozzle, i will not recommend to dip it in water….thermal shock. Air blowing is ok. But i must say that two hours of cutting operation is really long. As duty cycle, i must say that 10 min waiting is enough to cool down the tip to avoid this problem.
