Question #: 14618

Question: machine wont zero machine coordinates

Current Solution

The machine coordinates depicts the actual machine location and not the logical location for one of the G55, 56, etc. work offsets. If you need to zero the actual machine's coordinates, then you need to select the settings tab, click on the "reset interp" button at the lower right of the screen and zero each axis of the "encoder position" section. To reflect this value to the main digital readout (DRO), click on the "to DRO" for each axis.

  • HI..I am having a problem with my machine going off axis and not returning to zero

    Hi, can you elaborate on what you mean off axis? If the CNC router is milling correctly and then suddenly in a location that you would not expect, then you are exceeding the torque of the stepper motors and stalling. If the cnc router stalls, then the cnc router will continue but the software controlling the cnc router will not have the correct position of the cnc router.

    If this is the case, then you need to either reduce the acceleration, reduce the velocity, or both. Does the problem occur during the milling process or during the jogging (rapids)?

  • HOW DO I CALIBRATE MY MACHINE?

    In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

  • HOW DO I MAKE MY MACHINE SQUARE?

    I use a standard large "L" square used in construction. I run gantry up and down with the bit along one side of the square to make the square aligned with the x-axis. I then run the bit along the other edge and if I see space from the edge of the bit to the square, I adjust the gantry square by loosening and tightening the eye bolts that hold the chain at the ends of the table. Repeat as necessary to get the desired square.

  • when a 4 or 5 axes machine?

    It's on the list of high priority next machines. The existing machines can already do 4 axes, you will need a head stock and tail stock. The head stock must be able to accept a stepping motor of the choice you require.

  • WHAT KIND OF MATERIALS CAN MACHINE?

    There are almost no limits to the kind of materials you can machine. Anything from wood or plastic to exotic materials like stainless steel can be cut as long as the part can be safely and firmly held and the proper cutting tool and cutting speed are used

  • HOW DO CNC MACHINES WORK?

    A CNC machine takes codes from a computer and converts the code using software into electrical signals. The signals from the computer are then used to control motors. Since the motors can turn very small amounts the machine is able to move in highly precise movements over and over again.

  • WHAT CAN CNC MACHINES DO?

    There is virtually no limit to what a CNC can do. CNC machines are responsible for almost all modern day machining operations in manufacturing industries. They normally costs tens of thousands of dollars, or hundreds of thousands of dollars. Our machines can be used to engrave plaques, cut wood for kits, mill aluminum parts, and inject plastic components. All it requires is willing to learn and understand how to use the machines to accomplish what you want to do.
