  • Do you have data sheets available for the Adjustable Rotary Limit Switch and E-Stop (Emergency Stop) Button - 120v-10A/240v-6A?

    If the products have documents available, they are generally found on the product page itself, somewhere in the description or under the instructions.

  • Are there any videos detailing wiring of limit switches and stop button?

    This video may serve helpful on the homing and limit switches:
    https://www.buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx

    I don't go into great detail on the wiring, however. If after you watch that video and you still need a video, please let me know and I will make a video on the wiring of limit switches and the E-stop button.

  • How are limit switches connected to the AWC708 controller?

    If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

    For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

  • The rods in my blackFoot gantry connected to the x-axis motor are bowing or bending.

    We are using the 1/2" rods in the gantry now. You can opt to purchase 1/2" rods and new gantry sides which will accept 1/2" ID bearings.

  • Do you have any tutorial about conecting emergency stop buttom?

    We currently do not have a tutorial on setting up the emergency e-stop button, however it works very similar to a limit switch. (limit switch tutorial: https://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx)

    There is 2 sides to the e-stop, first being green NO-Normally Open and secondly being red NC-Normally Closed. From these two sides you will have too choose in which manner you would like to wired the e-stop.
    If you plan on smashing the button when there is a problem, (as we all do :D) we would recommend wiring it in normally open - Green side. The wiring is simple, you will only need 2 wires going from GND to the input pin, the orientation of the wires is not as important with these switches.

    Setup
    Mach 3:
    You will go to config/ports&pins/inputsignals, there will be one item in that tab enable, e-stop, you will then enter the pin number and you are done.

    Planet-CNC:(with our board) there is not designated pin which we would recommend wiring it directly to the power cord going to your CNC electronic power supply. Wire it in normally open and to the live/load wire.

    3rd party board compatible with planet-cnc or a direct planet-cnc board, go to file/settings/general, there you will choose the output pin for your e-stop as stated on the board schematic.

    "On a personal note: I have ran into 1 issue once being that they placed the colored covers on the opposite sides, which means that green is red, and red is green. I only ran into this once but I would rather share this info. as a possiblity."

  • 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.

  • Mach3 USB CNC Interface EMERGENCY STOP

    To connect an emergency stop (e-stop) to the Mach3 USB controller, use the emergency stop switch/button on the NO (normally open) connections of the switch. Connect one side of the NO connection to IN1 and the other side of the NO connection to the DCM, or GND (V-) of the 24V power supply that is used to power the Mach3 USB controller.

    Additional Information:
    The configuration in Mach3 should be default if you used the XML file that is here:

  • Should the spindle be connected to ground PE?

    The protective earth should be connected to the spindle housing in some way. Sometimes the 4th pin is already connected to the housing, but not always. It is always good to check by removing the 4 screws of the connector to confirm this. If it is not, you can use one of the connector screws as a way to connect the PE to the spindle housing. The screws of the connector has a direct connection to the housing of the spindle.

  • HOW THE ROUTER IS CONNECTED TO ELECTRONICS?

    The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

    If you are interested in the USB breakout board, you will need to get an independent relay board.

  • What are the EN connections used for on the QJ8060 motor driver? I notice that your video seems to leave them unconnected.

    The EN terminal on the QJ8060 driver and all of our other stepping motor drivers is the enable terminal. We don't use this terminal and the driver will function properly if left unconnected.

  • Need help configuring Planet CNC software to control laser firing. Currently it is firing using the Z axis but leaves the laser on after a run or when the emergency stop is activated. HELP!!

    To stop the laser completely from continuous firing after a job is complete, I recommend to have your file to end while reaching the clearance plane which you will enter in your CAM software. Make sure that your clearance plane value is very small (ex.) 0.001 above 0 and activates at -0.001 also adding a additional g-code manually that raises the z-axis towards the end of the job/run(only if experienced would we recommend using this). This will turn of the laser, rather than the laser staying on and at its current height.

    When activating the emergency e-stop, (personal opinion) I would wire the e-stop at the beginning of the live/load wire going to the electronics power supply and the laser power supply.
    It will be in at the beginning of the y connection, (https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/13/) so you will cut power to both instead of just the CNC electronics.

  • I cannot turn the shaft of my stepper motor. It not even connected to a driver

    The motor is creating it's own EMF when you try to turn the shaft manually. When coils are connected (or not connected) to any circuit that is not powered can cause unpredictable results.

    The motor freezing from just turning it by hand with no connection is surely the wires touching each other. This is actually how we test if a motor is good or bad. If the motor freezes when two of the wires are touching, that means the motor is functioning properly since the magnets are causing current to flow through that coil opposing the magnet.

  • Under what conditions should the LED on the 3d printer driver be lit when the driver is connected to the MB?

    The driver's LED serves to indicate a fault condition. The driver chip has built in protection for overheating and over current. If the LED is on, most likely, the driver will stop until the condition is resolved. If you see the LED on, adjust the vref trimmer. First, connect a multimeter to the pads just next to the trimmer potentiometer and adjust until the voltage is lowered a bit. Alternatively, even though the PCB contains a vast amount of thermal vias and a relatively large ground plane connected to the belly of the driver, there still may be a need to cool the driver chip using a small heat sink. Do this only if you are not satisfied with the performance of the motor at the torque require.

  • I have the book which has the plans. Are there cad files?

    There is currently no CAD files available with any CNC machines that we currently have on the market.

    However for our BYCNC book, we have a pdf file with all the parts you will need to fabricate here: (https://buildyourcnc.com/Documents/CNC%20Kit%201-1.pdf), however some modifications and updates have been made, which you can purchase the new files and DVD here: (https://buildyourcnc.com/cnckitintro.aspx).
