Question #: 14557

Question: laser wont fire...double checked wiring and all seems correct to diagram

Current Solution

Is there a test button on the laser tube power supply? You can test the laser output by using the test button. This will help you determine if the laser tube is bad, or if you have wiring issues. Sometimes, wiring to he TL may not work as some controllers are set to active low, so you may need to wire the controller to TH instead.

Additional Information:
Additionally, the mA on the high tension line does not have any relationship to the digital trigger signal from the controller to the power supply.

  • my motor only goes one direction. I checked all the wiring and it's correct. Any suggestions?

    The video showing the hookup of the large motors showed a sequence that was not correct, or I totally misread what was recommended. I hooked the first motor up that way and it would only go in one direction in a very jerky mode. I confirmed that i had hooked it up the way the video showed, disconnected the wiring that runs through to the motor and reconnected it, thinking maybe a cold solder joint was the problem. No good. I finally went to the motor page that showed a different connection pattern. I tried the one that the motor page said to do, and it works smoothly and in the right direction now.

  • 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

  • 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!

  • I have two nema 34 motors on my gantry and ordered a hex inverter, now I need to wire it correctly. What type of wiring hardware do I need and I will need a wiring diagram also. Please help.

    Have you considered reversing the A and B coils on one of the motors to the drivers? This will cause the motor to spin in the opposite direction. This is the easiest method. Using the HEX inverter is a more complex method and not recommended for simple driving tasks.

  • Have checked stepper motor wires dozens of times and they are wired like diagram says. Stepper motors will not turn under power. I am using laser control option. What should I do?

    This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.

    To move two stepper motors simultaneously with the same signal, simply wire the two stepper motor drivers to the same interface board signal terminals (CP and CW).

  • Do you have a wiring diagram for your breakout board and the SuperPID?

    It is not necessary for a wiring diagram for the breakout board to the SuperPID controller since you are only going to connect two wires from the breakout board output terminals of your choosing to the SuperPID controller. The only thing remaining is to configure Mach3 so that the spindle control section serves as the SuperPID controller.

    To setup this configuration in Mach3, go to your ports and pins dialog box (config menu -> ports and pins). Click on the spindle setup tab. In the Motor Control Section of the dialog, check the box for Use Spindle Motor Output and check the box for PWM control. Change the PWM Base Frequency to 50Hz.

    Here is the wiring diagram for the MAch3 USB breakout board:
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    You will need 24 volt relays for the output on that board since that side of the board requires 24 volt power at the V+ and V-

    Customer Response:
    My inquiry is for the Planet CNC USB and 5v relays.
    I am 99% finished with my 2 axis lathe build and this is the last item for me to conquer.
    I want to control power to router, and vacuum with the BOB going through the 5V relays purchased on this site.
    Thanks again.

    Using the Mist, spindle or flood pins...

    Buildyourcnc response:
    There is an IN, GND and 5V for the digital side to engage the relay. There is an S, O and P for the power line of the device to be controlled.

    The 5V and GND must be connected to the 5V and GND from the USB board. The IN is the wire from the output terminal (i.e. mist, flood, spindle).

    For the power side, here are the scenarios:
    - P to O connection is normally open
    - P to S connection is normally closed

    So, if you have the power wire that would plug into the wall, the L "black" wire from the power cord will pass through this part of the circuit (cutting the wire and one end in the P terminal and the other end in the O or S terminal). Generally, the P to O is used as this connection is normally open and when the relay is engaged, the circuit will close allowing the current to flow through that wire.

  • Hello! Question about the x motor on the vlxl. There is no black lead. Is the yellow in its position? Also, I really just want to double check that this wiring diagram is solid. About to finish the wiring. Juan told me to use the 36V for the tube and 24 for the drivers. Correct?

    The stepper motor on the X axis on the VLXL is this motor here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-nema34-651ozin

    There is no black lead on that motor and the connection diagram can be found here:
    https://www.buildyourcnc.com/Documents/PN.SM86HT80-5504B-U(inhouse%20PN.85BYGH450A-47-80)%20(1).pdf

    Red - A+
    Green - A-
    Yellow - B+
    Blue - B-

    The wiring diagram on the instructions for the Vertical Laser XL is meant as a general guide for all laser systems. The motor specific to the axis should be checked against the datasheet to insure proper wiring.

    The 24V power supply should be connected to the laser controller. The 36V power supply should be connected to the drivers to power the motion electronics.

    Additional Information:
    My fault. Must have had that backwards. I'm sure he told me the right way.

    Additional Information:
    Not a problem. The laser controller has two terminals labeled for the 24V connection.

    The 36V power supply works really well for stepper motor drivers as the voltage/current on this power supply allows for best stepper motor performance with this laser application.
