Question #: 5749

Question: Should the machine material (wood like) be painted before assembly?

Current Solution

Our machines structures is made from MDO, which is used in the construction industry. Specifically in cement forming, which allows the material to be treated and coated for the specific requirements in the field.
We do recommend painting the structure (everything structure wise besides aluminum) with oil based paints, if you have the machine in a very humid location or location with constant rain. If you do not have the machine in a climate control environment.
Painting the machine will not give it a longer run time or any specific advantages to the over structure or material. Painting it would be more of a personal choice, in making it specifically orientated to your shop or personality.

Other Possible Solutions to this Question

  • Can a CO2 CNC laser machine be used for welding of thermoplastic materials?

    That is a good question. We have not tried to weld thermoplastics using our CO2 Lasers. It is possible since the laser outputs a heat source and at the right intensity and speed, the thermoplastic can be heated and melted rather than instantaneously vaporized and off gassed. I have done research to see if CO2 laser can weld thermoplastics with positive results.

    Our CO2 lasers are typical of other laser cutters on the market, so if their literature, or examples you have found, successfully weld thermoplastics, then ours will probably be able to as well.

    In some cutting test with different speeds and intensities, the kerf has welded back together; however, this was caused by an unintentional process rather than an intentional one.

  • How thick can the material to be engraved will fit inside the BlackTooth machine

    The thickness of material that can be cut or engraved is addressed in other CSL answers.

    The thickness of material that will physically fit into the machine is limited by the distance from the bottom of the cabinet to the laser nozzle, which needs to be at a distance from the workpiece determined by the focal length of the lenses used. (2 inches is standard in our machine.) The standard cabinet of our blackTooth has a cut out section about 25 inches wide designed to allow a sliding tray to be used to easily change workpieces. You could allow for material of any reasonable thickness by adjusting the thickness of this tray so that the surface of your workpiece is the proper distance from the nozzle. You could also modify the cabinet as needed to accommodate special sized work.

    If you need to lase very large workpieces, you might consider our Vertical Laser XL, found here: https://buildyourcnc.com/item/cnc-machine-vertical-laser-xl, or adding a laser tube to the spindle of one of our conventional CNC machines, such as this: https://buildyourcnc.com/Item/cnc-machine-laser-spindle-combo-head.

  • WHAT MATERIALS CAN THE GREENBULL MACHINE CUT? LASER ETCH?

    The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



    BYCNC Response:
    Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

  • WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE

    The blackfoot requires a total of 50 feet of cable.

    The X axis needs 15 feet
    The Y axis needs 17 feet
    and the Z-axis needs 18 feet

    These are 20 gauge 4 conductor cable.

  • WHICH MACHINE SHOULD I BUY, THE GREENBULL OR BLACKFOOT?

    The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

    Previous Solution:
    The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

    The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

  • How should I connect the E-stop to the machine?

    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.
