Question #: 14532

Question: What is the wiring configuration for limit switches on the laser controller?

Current Solution

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.

  • When using the laser controller, what does "engrave beyond border limit" mean?

    LaserCAD: Engrave beyond border limit.

    This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

    Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • Using USB Controller Board with Planet-CNC software. The S/W recognizes limit switches but not soft limits. Help?

    "Soft limits are used to decelerate machine to stop before machine is stopped hard way at limit switch or before it crashes. I recommend "Soft Limits Decelerate" and "Soft Limits Strict" settings are also checked. Sometimes we need to disable soft limits and there is a command for this in menu "Machine/Soft Limits". When soft limit is triggered position display will be yellow."

    Are the soft limits "grayed out"?

  • Mach3 USB interface board. Could you please give me the correct wiring configuration for tool prob?

    Depending on the probe that you have, you should have two wires coming from the probe. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4):
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    The other pin is connected to V-. Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board.

    The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit).

    If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.

  • I am using 5 limit switches on my 3 axis machine. I am using the usb controller for planet cnc. I would like to know where all the wires related to the limit switches get connected? A diagram would be helpful.

    The diagram for wiring the USB interface board is located here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/

    Under the board illustration, there are three smaller diagrams of limit switch wiring. On each, there are two connections, the GND and the pin which are labeled at the ends of the circuit on the diagrams. The pin side would go to the axis label ++ or -- terminal (i.e. X++, or X--). The other end, labeled GND would connect to any ground terminal on the board.

  • Can you tell me what gauge wire is needed for limits switches and the spindle?

    The hookup wires you will need is 22 to 24 AWG stranded and shielded for the wiring of the limit switches and E_Stop. Our kit customers select various places for these switches, so we don't supply the wiring. If you don't use shielded cable, you will need to change the debounce setting in Mach3 (if that is the control program you are using).

    We typically use 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections.

  • 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.

  • Do you sell 22 to 24 AWG stranded and shielded for wiring of the limit switches and E_Stop?

    The wire that we sell for the limit switch wiring is here: https://www.buildyourcnc.com/item/3d-printer-component-cnc-electronicsandmotors-cable-wire-3-conductor-22-awg-wrcon-cablewire3conductor22awg

    This is shielded cable to make sure there isn't any external interference with sensitive components and long wires associated with limit switches. This is necessary due to the interference caused by the motors on a CNC router and the milling process.

    Additional Information:
    So unshielded is cool. That's what I was curious about. Cheers.

    Additional Information:
    Absolutely. It's really the only type of cable I would recommend for connecting limit switches.

  • Is there a wiring diagram for hooking up your hex inverter between your USB breakout board and the controller?

    The use of the hex inverter in the application to invert a direction signal to have a motor run in the reverse directions is relatively simple.

    First, go to this link and look at the chip diagram:
    https://www.buildyourcnc.com/item/electronicsAndMotors-hex-inverter-breakout-newbiehack-integrated_circuits-hex-inverter

    Connect 5V from the USB interface tothe VCC pin. The pin on the keyboard jog header can be used. Connect the GND pin from the USB interface to the GND pin on the hex inverter. Connect the CW terminal from the USB interface to the 1A pin on the hex inverter. Connect the 1Y pin from the hex inverter to the driver.

  • What electronics configuration is included with the blackfoot if I choose that option?

    There are three options on the blackFoot product page.

    Two options include either electronics that use the USB interface, or parallel interface. Both of these options include stepping motors (two 425 oz-in and one 651 oz-in), motor drivers (two 3.0 amp and one 6.0 amp), power supply and either a parallel breakout board, or USB breakout board. The USB interface must be used with the planet-cnc software. The parallel interface can be used in a wider variety of control software but will require a parallel port on your computer. If a parallel port doesn't exist, you can purchase a PCI parallel port adapter (for desktop computers only).

    The other option does not include electronics. This option is if you already have electronics, motors and drivers that will work with this machine, or you wish to purchase the redLeaf or redSprout assembled and plug and play CNC electronics and computer system.

  • Do you have a wiring diagram for a 3 axis system using your compotents. It would be nice if it showed the estop, limit switches,relays...

    Depending on the Breakout board that was purchased with your electronics combo, either USB or Parallel:
    USB: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/
    Parallel: https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/

    These will have the inputs labeled on the board itself, for example:
    USB will have the inputs for all the axis from X, Y, Z, A, limit switches.
    Parallel there will be 4 inputs 10, 11, 12, 13, 16(relay). Which can be used as E-stop, Limits (for all axes if wired in a closed loop), and one relay for a spindle control on/off via mach 3 or mach 4 or a specific relay control that you desire.
