Frequently asked questions about CNC cutting machine
Here are some frequently asked questions about ARCBRO CNC cutting machine. Hope it will be helpful to customers who use our cutting machine.
Q1: The machine has no Oxygen flowing. Any info you have about this? Info about solenoid valve?
A1: The problem has 5 possibilities:
- Check if you have connected the solenoid valve cable, if yes, check if it is connect well;
- Check the solenoid valve, when you press the button of [cutoxy], if you can hear the sound of ‘Pa’ from the solenoid valve, if yes, the solenoid valve is good;
- Check the relay, measure the voltage if it is 24V (on or off);
- Check the programme, if it has the code of M07
Q2: The information from a memory key is not read out. Why?
A2: Programs should be entered manually.
The machine reads out the name of the program from a memory key, but does not load it. At use of other memory key the result similar.
- please check whether the file in the memory key is only the program file;
- please check whether the length of file’s name over 6 characters. If yes, please shorten the file name.
Q3: I currently use solidworks (sheet metal). Can FAST CAM translate into CNC cutting machine?
A3: If you solidworks CAD software may save the file in .dxf extension FastCAM may translate your drawings into cutting programs.
Q4: After a long time cutting, the tip becomes very hot. What should I do to cool down it?
A4: 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, 10 min waiting is enough to cool down the tip to avoid this problem.
Q5: What should I do if the torch movement is block?
A5: Concerning the non-falling out pieces who can block the machine. If the torch movement is block by anything else, this will create an over-current rush on the stepper motor, this inrush current will be detected by the current limiter circuit and the machine will switch off by itself. As it is an accidental power off, applying the correct procedure (describe in the user’s manual), the machine will be re-started at the point of the program when this power off occurred. I must say that, the point you are mentioning is general to all CNC cutting machines.
