Question #: 13826

Question: Can i wire my drivers and motors in parallel to your laser controll system to add a laser unit on my router?

Current Solution

It is possible to add the laser control system to an existing CNC router but there are a few considerations:

All of the signal wires from the laser controller that connect to the drivers drivers and all of the signal wires from the CNC controller that go to the drivers will need to first pass through a tri-state gate buffer chip that will allow one set of signal wires to be switched off and the other set switched on.

We have a board that does this in development, but If you wish to accomplish this on your own, you will need:

- 3 Quad buffer line drivers (each one can receive 4 signal wires): https://newbiehack.com/categories/newbiehack-integrated_circuits-buffer-quad-buffer-line-driver-throughhole
- Some perf board, solder and a soldering iron, and some hookup wire.

If this doesn't scare you, please feel free to submit additional information and let me know if you would like more information.


Additional Information:
You will also need a physical switch to select laser control or CNC control.

  • Can I wire in a 5vdc relay board to the spindle relay for my router. Gnd would be negative and the arrow would be positive right?

    Yes, a 5v relay board can be connected to a spindle. Relays generally have terminals labeled S, O and P and you will want to pass one of your main wires "through" the P and S terminals or the P and O terminals depending if you want normally closed or normally open function.

    User response:
    I have the USB board. I was thinking of wiring a 5v relay board to the breakout board labeled (spindle) using the GND and (arrow) which i think is 5vdc. I will need this relay board to operate my router. Thanks

    Buildyourcnc response:
    Yes, those terminals are to control the relay (engage the relay). On the switch part of the relay, the router main poser wire (say, the live, black, wire) would pass through this switch portion of the relay.

  • How can I connect my pc to my motor drivers and motors?

    All you need is a CNC controller like the following options:

    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

    Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

  • Can I have two motors and drivers on a single axis?

    Yes, you can have two drivers connected to a single axis. If you want the two drivers/motors to work as a single, more concerted pair, then I would suggest connecting the two drivers to a single step pulse and direction signal.

    That is to say:
    driver 1 and driver 2 have wires connecting from the CP terminals of the drivers to a single step terminal on the interface board (USB or parallel breakout board), and the CW terminals of the drivers connected to a single direction terminal on the interface board.

    If the motors need to spin in the opposite directions, simply reverse one of the the motor A B coil connections (i.e. wires that would go to A+ and A- is connected to the B+ and B-, and the same with the B+ and B- to the A+ and A-). You can alternatively resolve this mechanically if desired.

  • I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

    Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

  • I am interested in getting your 40W laser system. How difficult will it be to increase the size to 48" x 48"?

    The blackTooth machine, as it is designed cannot be modified easily as the box within which it is contained also serve as its structure. We are currently designing a special mount for the greenBull (for the 40 watt tube) which will provide 5'x10' or 6'x12' work area and the machine is far less expensive than comparable 4'x8' laser systems. We are also developing a 4'x8' 80 watt system where the tube is in the horizontal orientation. More information can be found in the R&D section.

  • My x and y motors are on each end of my gantry do I wire each motor to the same XP

    I'm not sure what you mean by XP. Can you clarify? Thanks.

    All stepper motors must be wired to their own stepper motor driver. If two motors need to be driven by one signal (say there are two X motors) then the two drivers will be connected to same CP (pulse or step) and CW (direction) pins on the control interface. If the two motors need to turn in opposite directions, then swap the A and B coil connections.

  • I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

    The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

    Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

  • Can I put a laser on my cnc router that I didn't purchase from buildyourcnc?

    We don't have a laser kit to retrofit another CNC router other than ours, but we can create one. Some things that may help:

    - You are located close to use so we can work closely with you to implement to retrofit,
    - or you can provide very detailed drawings or measurements so we can use them to create the necessary parts for the kit.

    Other things that you need to understand:

    - A laser has a number of parts that will bulk up the head of the CNC router causing a bit more inertia which may require lowering the acceleration for smooth ramping up and down of the velocity

    - The bulk of the parts required for the laser may restrict the travel of the x and/or y axes.

    - The nozzle of the laser will be offset from the end mill of the spindle.

  • I have your breakout board with relay parallel port , I have a vacuum, light on router and air pump I want to also hook up to board, can I hook those up to board and also could I had reylays to each one, what is the best way to figure this out any information would be great. Thanks

    Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

    See this image of a similar connection. The terminal has the same connections.
    https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG

    Image of the relay terminal:
    https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

    The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


    Additional Information:
    You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

    Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

  • I am asking what to set my steps per using your kit stepper motors and a 1/2"x13 lead screw with Mach3

    Here is the formula for steps/inch (steps per inch)

    Steps = how many steps for a full ration of the motor = standard motor steps x number of microsteps for each step
    Standard motor steps for our stepping motors is 200 steps per revolution.
    Microsteps are selected on the driver and are shown as full, 1/2, 1/4, 1/8, 1/16, 1/32 etc... Use the denominator for the number of microsteps per step.

    Inches = how far the travel is for one full rotation of the motor. For the 1/2" - 13 TPI (threads per inch), the travel length will be 1"/13 or .076923". So, for one revolution of the motor, the travel distance will be .076923 inches.

    So, the steps = 200 * microsteps, let's make this 1/4 just for the formula.
    The inches will be .076923. Plug those into the formula:
    Steps / inch = (200 * 4) / .076923 This can also be written as:
    200 * 4 / (1 / 13) = 10,400
