Question #: 411

Question: WHY SHOULD I BUY THE SPINDLE?

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.

  • 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.

  • [77] What circuit breaker should I use for this spindle?

    The 2.2kW spindle has a power rating of 2.2kW or 2200 watts.

    If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work.

    If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work.

  • What Should I buy to complete the basic laser kit

    The laser components needed for a typical CO2 laser cutter and engraver are as follows:

    - The laser tube and laser tube power supply. We currently have 40W and 80W choices. The laser power supply must be pred with the laser tube (40W power supply with 40W laser tube, for instance)

  • 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.

  • How should I wire the E-stop button? NC or NO?

    I would recommend wiring the E-Stop to an input terminal via an NC connection. This is the industry standard. It requires a NC (Normally connected) circuit for the machine to be operational, and when the circuit breaks, the machine shuts off. This is better than having a circuit NO (normally open), open circuit that requires a circuit to be created to have the machine shut off for safety.

    Having en E-Stop run through the mains line would only work for a single circuit (or use multiple E-stops, which defeats the purpose). The E-stop connected to the input terminal would shut off all machine functions.
