Question #: 6850

Question: I believe I understand USB v Parallel BoB on the Blacktooth but what is "integrated computer" mean?

Current Solution

Integrated computer for our blackFoot means, that the computer components will be included with that kit. Meaning that a motherboard(mini itx) with a on-board processor, RAM, HDD and power supply is sent.
So the blackTooth will be a all in one kit, excluding any software with the price.

  • from what I understand, The BlackTooth Laser comes with an open bottom with no bed, does one pull air through this opening for fume ventilation through the bed?

    On the blackTooth laser cutter and engraver, the ventilation is at the back and there is a slit at the bottom front so when the machine is placed on a surface, the air will move from the front of the machine and out the back through the ventilation. This will move the particles past the mirrors and tube output efficiently with a reduced likelihood of building up on these important surfaces.

  • On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.

    The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

    If you use the TL or L terminal to control the laser:
    If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

    If you use the TH or H terminal to control the laser:
    If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

    You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

  • what is the difference between parallel and USB electronics. I have a laptop that will run the mach3 program.

    The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

    The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

    The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

  • WIRING THE BLACKTOOTH LED PANEL TO PARALLEL BOB

    The blackTooth build instructions explain how to hook the four LED control panel to the USB breakout but not the Parallel BOB. Turns out it's very easy. Simply wire the corresponding LED cathodes (top pins on the display) to the matching CP- for the X, Y, and Z axises and wire the anodes (bottom pins) to the 5V terminals. For the on/off LED, wire the cathode to the G terminal on the laser power supply and the anode to the 5V laser supply terminal. Also, remove the 5V wire running from the Parallel BOB to the 5V terminal on the laser power supply. It is not needed and will cause the laser on/off light to always be on if the USB cable is connected.

  • The parallel break out board on the Blacktooth machine has the parallel 25 pin socket, and also a usb socket. Should this usb socket be connected to the computer's usb port as well as the printer cable being connected to the printer socket?

    The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).

  • What is the dot resolution (size) of the BlackTooth laser?

    The dot resolution of the blackTooth is a combination of two specifications of the machine:

    - The steps/inch (or steps/mm) which is the resolution but not the dot size
    - The size of the actual dot, which is not specifically related to the resolution.

    The steps per or resolution can actually be a range, since the driver microstepping can be modified.

    A simple formula can be used to determine the resolution:

    step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)

    if microstepping is set at 16 (1/16 on the driver) and you are using a pulley that has a pitch of .08 inches and 20 teeth on the drive sprocket

    = (200 steps * 16 microsteps) / (20 teeth * .08 inches)
    = 3200 steps / 1.6 inches
    = 2000 steps per inch

    To increase the resolution, just increase the microsteps on the driver.

    The actual dot size will depend on the lens you are using, the material being lased, the time period that the laser energy is applied to the material, and the focal height of the lens to the work surface material. The energy from the laser will converge to a point and create a dot on the surface (which is different than the kerf of the laser cut into the material).

    The dot will appear in different sizes depending on the material because, say wood, will burn causing a dot that burns the fibers of the wood and spreads a bit. The dot lased on the surface of a plastic, say Plexiglas, the dot will be smaller because the energy is absorbed only at that point, but since Plexiglas is a thermoplastic, a bit of the energy will melt the dot edges depending on the time frame (period) that the energy is applied to the surface.

    The focus of the laser energy from the lens looks like a cone converging to a point, then diverges outward after that point. Depending on the distance from the lens to the surface of the material, the dot will be bigger or smaller. You want to find focal point (where the energy is focused into a point). You can use the technique where you lay a material on a slope and lase that material along the slope to find the sweet spot (dot) and that will be your smallest dot, or kerf location. Remember that the kerf will widen or narrow within the material thickness depending on the focal length lens specification (the cone will be shorter or longer depending on the lens focal length).

  • Hi, whats the actual (with the fixed errata) laser electronic wiring diagram for the blacktooth? thank you

    Which wiring diagram are you specifically requesting? Due to your current model blackTooth? We currently have two wiring diagrams, Parallel Interface board (https://www.buildyourcnc.com/images/LaserWiringParallel.jpg) and the USB interface board (https://www.buildyourcnc.com/images/LaserWiringUSB.jpg). Also if you have the new model blackTooth with the control unit, we still do not currently have that wiring diagram in a document format!

  • What solder will stick on the tungsten terminal of the laser tube in a Blacktooth kit?

    We use a standard leaded solder with flux. To help the soldering, you can add flux to the wire end and the tungsten rod. We have not tried non-leaded solder in fear that we would crack the glass with a rapid temperature rise. The leaded solder will melt at a lower temperature.

  • WHATISTHE DIFFERENCE WTIH THE PARALLEL BREAKOUT BOARD AND USB BOARD?

    The parallel is the most versatile breakout board we have and will work with most of the software out there, but many computers are not equipped with parallel connectors anymore. Parallel adapter cards are available if you don't have a parallel connection on your computer.

    The USB interface must be used only with the planet-cnc software, which is great software, but you are still limited to only that software application. This is actually the least expensive option unless you use linux and go with the above option.
