Question #: 483

Question: MY LIMIT SWITCHES ARE TRIGGERING AT RANDOM.

Current Solution

Are you using shielded wire? If so, take the shield to ground. If there are any other wires in the cable that is not being used, ground those as well. The customer can also try moving the cables as far away as possible from the motor wires and motors.

  • I HAVE A 2000 WK 11–3 Z LIMIT SWITCHES GOING TO C10R10 BREAKOUT BOARD . CAN ALSO USE THEM AS MY HOME POSITION WELL. NEED THE WIRING CONFIGURATION

    No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

    I will answer the other question as another FAQ. Please check the Customer Service page to see the answer to that question.

    HOW DO I SET THE DIP SWITCHES?

  • THE SWITCHES KEEP TRIPPING! AT TIMES IT IS LITERALLY AS SOON CLICK RESET ON MACH 3 THEY TRIP AGAIN.

    http://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx
    There is a pin setting in Mach3 that says how to react to the inputs from the switches. Your setting is probably wrong as the trigger happens immediately.

    You may want to think about shielded wire and/or a resistor on each limit switch line. If there are stray wires, connect them to ground. Additionally, the shield from the shielded cable insulation should alse connected to ground at both ends.
    Try upping the Debounce interval in Mach3. You have to adjust the debounce interval. You go to config,general config, and it is in the top right corner. I set mine to 100 and it seems to work well.

  • MY PARTS ARE COMING OUT THE WRONG SIZE

    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.

  • LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.

    BYCNC Response:
    This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

    User Response:
    I am using the cnc planet software for your USB board. Are the limit configurations in this software?

    BYCNC Response:
    Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

  • MY MOTORS ARE RUNNING VERY HOT.

    If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

  • DO NEED LIMIT SWITCHES, IF SO WHAT IS YOUR RECOMMENDATION?

    Limit switches are not really needed for this level of a machine, but if you do want to use them, then you will need to connect them with shielded cable and ground the shield at both ends and any other non-used wire in the cable. Limit switches are very susceptible to the motor interference. You will also need to adjust the debounce in the software you will use.

  • WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?

    Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
    To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
    The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
    Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

  • THESE MACHINES ARE DANGEROUS, WHAT DO DO?

    These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

    With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

  • WHERE ARE THE ELECTRONICS WIRING VIDEOS?

    The blackFoot CNC machine kit does not include a table. The table can be made as long or shot as you need. for instance, if you are looking for a travel of 4 fet x 4 feet, then the table will need to be about 6 feet long to get the full 4 feet of travel.

    The electronics are very straight forward using the connection diagram for the breakout board that you select. Use the videos for a general idea and then use the connection diagram to verify the correct connections for the interface of your choosing.

    Yes,the USB interface replaces the breakout board, but remember that you will need to use the planet-cnc software with the USB interface.

    Additional Information:
    The electronics does accompany the cnc machine kits as long as you select the option "with electronics". There are option to purchase the machines without electronics and that would be necessary if you either have your own electronics, or you prefer the plug and play cnc computer system we call the redLeaf, or redSprout. This will also be necessary if you prefer the electronics that use the USB interface rather than the parallel interface.
