Latest Frequently Asked Question about CNC Cutting Machine
Founded in 2008, ARCBRO is a group company. We are total solution provider for portable CNC cutting machine, including the plate cutting and the pipe cutting. Today we are going to share the latest frequently asked question about CNC cutting machine:
Q: How are the FAST CAM programs uploaded to the machine?
A: 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 ArcBro 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 ArcBro.
Q: For the FastCAM software On installation it asks us to choose the control type?
A: The list is :-Burny 3 5 10，Edge EIA，ESSI，Fagor，Lynx EIA，START，KangPu，Koike，FastCNC
When you use the ArcBro machine,Please choose “START”
Q: How does the programming work?
A: 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.
Q: Will software import and convert scanned images?
A: With the optional FastCAM Outline Software you may translate a picture file (.jpg,.bmp,awg,…) into a .dwg file and then to a cutting program.
Q: How to adjust the parameter of the machine?
A: In order to regulate that:
1. Press F4 PARA

Q: I tested to cut with Hypertherm Powermax 1000. I have difficulties to set right speed parameters. Sometimes arcs was going too slowly and with some parameters there was too much vibrations. can you help to find right parameters for ArcBro?
A: Set right speed parameters:
method 1:a, preess[F4]PARA–CTRL–WORKSPEED(adjust the speed)–SAVE,b,press [F↓]、[F↑]to adjust the rate of speed.
method 2:a,add a speed control directive in the program –F***，b,press [F↓]、[F↑] to adjust the rate of speed.
Q: Could you describe the process of beginning of cutting – manually or automatically?
A: The process to begin cutting manually: you open the fuel valve, the pre-heating oxygen valve and with a lighter you light the flame. To open the cutting oxygen after having open the valve of the torch, you press on one button of the keyboard (oxygen). In automatic, after having do the same that in manual, in the programe you have inserted the command M07. Before you will have made an adjustment for the cutting oxygen flow. This is the process for flame cutting. If you are using a plasma cutter in manual, you open and adjust the oxygen flow and press the keyboard button to ignite the torch. In automatic you insert in the program the command M07 (M08 in both case will cut the oxygen)
Q: Is the plasma ignition on the machine automatic or manual?
A: Two way to ignite the plasma: in manual pressing the corresponding key from the keyboard: pressing ” cut” will ignite the plasma, pressing “cut off, will stop it. The other way is when you are using the automatic mode, you insert in the cutting program the command M07 to ignite the torch, M08 to stop it. But please note that in case of you are using the FastCAM cutting software to make a cutting program, the software will add these commands by itself.
Q: Why I tested to cut 100 x 100 mm square? Other side was 100 mm and other 99 mm.
A: There are 3 possibilities:
1)the torch is not mounted vertically to the plate surface£»
2)Check also if the cut kerf is vertical to the metal sheet (in case of plasma, the kerf has a angle between 3-5 degree;
3) If it is not the previous 2 cases, the system M and N parameter needs to be modified. please check and provide us the M and N parameter of the system, here is how to get the M and N data:
press[F4]PARA–SYST–N? M? , read the data of M and N and tell us.
