Question #: 127

Question: Why should I use a spindle rather than a router?

Current Solution

The spindle is quieter and has more consistent torque (It doesn't get "bogged down" when it starts cutting into material). It can be used with collets of varying sizes (not restricted to imperial sizes). It is water cooled and so it does not blow air downward to cool the spindle like the router does. The spindle is also machined with much higher precision than typical routers and will have a much longer life.

Other Possible Solutions to this Question

  • What kind of wire should I use between the invertor and the spindle?

    The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

    The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

    Currently we use 20AWG 4 conductor.

  • What relay should be used with your USB BOB for controlling mist/flood/spindle on/off?

    The relay that should be used with your USB BOB for controlling mist/flood/spindle on/off is one of the following options.

    You could get and use the Planet-CNC.com Output Board found here, http://www.planet-cnc.com/index.php?page=shop

    Or you could create your own setup using a resistor, solid state relay, transistor, and diode. You can watch this video, https://www.youtube.com/watch?feature=player_embedded&v=PJO_XoLL6lQ, to find out the correct way to accomplish this.

  • I currently own a blacktoe router cnc.Want to convert to spindle.Do I use the same Z axis mount?

    You will not be able to use a router mount for a spindle. You will need to get a spindle mount for your Z axis.

  • I own a blacktoe 2x4 cnc. I need to convert to 2.2kw spindle. I cuurently am using the porter cable router spindle.Thanks.

    We will have to replace the motor mounts that the router currently is mounted to. The process is easy we will need to communicate, through our email or over the phone.

    If you would like to use a spindle rather than a router on your existing CNC, we will send you another set of components that will allow the spindle to be mounted properly which includes the z-axis rails, rail support, spindle mounts and the dust shoe components.

  • What is the benefit to using a spindle over a standard router?

    This solution will refer to the water cooled spindles that we sell. Generally, routers are air cooled which push air downwards through the router to cool the router motor. This has an undesirable effect for CNC machines that will blow the dust and chips into the air. The water cooled spindle will not blow since it uses water to cool the spindle motor. This allows the chips and dust to be confined within the dust shoe and get removed by the vacuum. Additionally, standard routers have a sound level that far exceeds that of the spindle.

  • Should the spindle be connected to ground PE?

    The protective earth should be connected to the spindle housing in some way. Sometimes the 4th pin is already connected to the housing, but not always. It is always good to check by removing the 4 screws of the connector to confirm this. If it is not, you can use one of the connector screws as a way to connect the PE to the spindle housing. The screws of the connector has a direct connection to the housing of the spindle.

  • Which spindle should I use for PVC and Trespa (Hardwood)? Max diameter of cutter = 16mm Max thickness plate = 20mm
  • When connecting homing switches, should I use more than one input?

    It is ok to connect the limit/homing switches to the same input.  The machine will go through a procedure that will start with the first axis, hit the switch, pull off, move more slowly for better accuracy, then pull off again.  This procedure makes sure that the input is always in the correct state while homing.

  • How should I control a plasma torch, spindle and a laser on my CNC machine?

    It will depend on how you configure the machine to use the Laser and plasma. Is the laser on a separate gantry? That will determine the way you will connect the laser control system or if you use a typical CNC controller. The plasma will need inputs of THC on, THC up, THC down and outputs to trigger the plasma torch. I recommend the Pokeys57CNC for the plasma and you can also fire the laser with it, but you will not be able to do engraving with the laser unless you use a laser controller. If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using, or if you have the laser on a separate gantry, you can use a traditional laser controller connected to the stepper motor drivers on that gantry.

    Users response:
    I was planing on using same gantry, and installing plasma and laser module on z axis along the side with current router. Perhaps if it’s needed installing another z axis on current z axis. So that when I use plasma, router z will be homed and plasma z axis will be able to utilize thc.

    When you say “If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using,”
    If i install laser controller, pokeys and router motion card, do you mean all ( axis and router/laser/plasma) signals or just the one that controls router/laser/plasma?
    I was wondering if I could jump (parallel connect) axis signals from card to card without ?
    Also do you prefer ethernet card or usb?
    I really do appreciate your help :) thanx again.

    Buildyourcnc response:
    Not a problem at all.

    Remember that with all of that weight on the z-axis, you will not be able to do efficient raster style engraving.

    By putting the laser on another gantry, say at the far end of the table, then you would be able to use a laser controller that controls its own stepper motors and the nozzle can have fast swing motion for engraving. With the laser on the z-axis of the spindle (like see on the greenBull), you will only be able to do vector motions for the laser.

    You can also have a CNC interface and laser controller controlling the same stepper motor drivers, but you will need a few tri-state buffer chips where you can use a toggle switch for which controller has control of the drivers.

  • When we simulate cutting a part, the part is 40% larger than it should be. Why?

    What software are you using to simulate the CAM machining operations?

    Additional Information:
    I drew my part in ViaCad, opened part in CamBam to produce GCode, then Mach3 to simulate cutting part. Everything worked as it should but part was too large.

    Additional Information:
    It sounds like steps per unit is not calibrated properly. Use the Mach3 to calibrate the axes. In the settings tab, there will be axis calibration labeled just above the reset button. There is a button just just below axis calibration called set steps per unit. When the button is clicked, mach3 will present you with a dialog box asking for a measurement of how far to move the specific axis you need to calibrate (use a number that will not make the machine over run the axis). The machine will move to a certain length. Measure that length and enter it into the next dialog box that Mach3 presents to you. Do this for each axis.

  • I'm looking to upgrade my X-Carve with one of your vfd spindles, can you reccomend which one to use to replace the dewalt 611 router?

    If you would like to replace a router that outputs a relatively low HP (horse power) such as the Bosch PR20EVSK or Dewalt 611, both having about 1-1.25 HP, the 1.5kW spindle would have more than enough power and will also provide constant torque where the routers are unable to achieve. The 1.5kW spindle outputs 2 HP and is water cooled to keep the dust out of the air!
