  • Do you have a more detailed diagram of the rotary and 15A limit switches on the vlxl?

    Are you trying to determine how to wire the switches or where to place them on the Vertical Laser XL? Let me know and I will provide some pictures or video on how to do this.

    Additional Information:
    Kind of both. Have somewhat of an idea as to how to wire them but you included rotary and other limit switches. Not sure which ones to put where. Never worked with these before.

  • I have a usb cnc driver board on your 1'x3' cnc and i cant get the z+ limit switch to stop the machine in the provided software. It registers the button but doesn't inhibit movement. inversly the button works when selected as '-' for negative movement.

    All USB boards, are tested and checked before shipment for all axis, and inputs. Here is a link with clear instructions on how to setup Planet-CNC (http://www.planet-cnc.com/faq/machine_setup/).

    Please check continuity and for any crossover disruption when wiring your board, try to wire each as cleanly and with out crossing any live power wires and or motor motion wires.

  • How do I wire the limit switches on the VLXL? Also, where do I place them? You included 2 rotary and two other limit switches.

    You can actually select many places for the switches, depending on where you think your zero will be. I will take pictures of where we positioned our switches. We set the positions so the zero is at the bottom left corner of the machine.

    Additional Information:
    I will take pictures tomorrow.

    Additional Information:
    Thank you. Just want to finish before the holiday.

    Additional Information:
    Not a problem at all and my apologies for not having that information. I have been meaning to put up a video on the limit switch connection as it is somewhat difficult to explain the process in words and diagrams.

    Additional Information:
    Any update?

    Additional Information:
    I plan on driving to the office later today and take pictures.

    Additional Information:
    Thank you. I've just done almost everything else. Just waiting for the grade 3 grease in the mail. Also, where do you suggest connecting the cable carriers? I ran everything through the top but the carrier is getting kind of full. Because of that, it is pushing the belt out when the gantry moves.

    Additional Information:
    I will take pictures of those connections as well.

    Additional Information:
    Much appreciated.

    Additional Information:
    It’s my pleasure.

    Additional Information:
    I’m almost to the office. I’ve been shuttling my kids around today. Sorry for the wait.

    Additional Information:
    I’m adding the images to the end of the VLXL instructions.

    Additional Information:
    The limit switch connections use the NO (Normally Open) terminals. That means that the switch, when not engaged, is normally open (no connection between the com and the NO terminal). When the switch is engaged, then the connection is closed and the NO and COM terminal become connected, making a circuit.

    Additional Information:
    Did you bend the arm on the x switch? Or can you mount it flush with enough give to trigger? Same on both sides?


    Additional Information:
    It does look like it is bent in the picture. No, you do not need to bend the arm of the rotary switch.

    Additional Information:
    We only have the rotary switch on one side.

  • 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.

  • 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.

  • Limit, E-stop and home switches: To set up the maximum number of switches set up I would need 2 BOB's, correct? How is this implimented and wired?

    The parallel breakout board allows for 4 input connections. Each input connection can have an unlimited number of switches, but if you need to separate the switch circuit for, say, all of the home switches, you can use another input pin. There is no need to add another breakout board to add more switches unless you need to use the input pins for totally unique conditions that may or may not be related to CNC functions.

    Customer response:
    To Clarify: I need to set up 3 home switches which can double for limits (that's 3 pins.). Another pin for a probe. That's 4 pins used. Now I need to set up the other limit and E-stop switches. No pins left, how do I do that? Can a ground pin be doubled up on?

    Plus, I have a SuperPID. Another pin?

    Additional answer:
    You can put all of your limit switches (including the E-stop which serves the same purpose as the limit switches) and home switches on a single pin. When homing, mach3 will move the axis it wants to home, hit the switch, pull away from the switch, then move the next axis and repeat the steps for the next two axes.

    The probe is on the 2nd pin. The SuperPID is on the 3rd pin and now you have another pin remaining.

    The GND terminal can be doubled up.

    Additional Information:

  • I recently received missing stop button and limit switches in my 5x kit. Thank you. Is there suppose to be any bulk wiring in kit for limit switches and 2.2 spindle? If not could you please describe correct gauge wire for both? Cheers.

    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.

  • Do you guys have any videos showing how to connect limit switches to a redleaf? If not, could you please make one? I looked at the diagrams on the limit switch page but I don't understand them.

    Connecting the limit switches on the redLeaf use the input pins on the parallel breakout board. Here is a link to the wiring diagram for that parallel breakout board.

    https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/

    The connection is simple. Just create a circuit from ground to the pin. When the pin is engaged, the circuit is closed (using normally open on the switch). Use mach3's autoset to automatically set the pin for the limit or home setting.

  • Hey Guys, I have a brand new redleaf and 5x. In the final stages of wiring and wondering a few things. Can I connect the Mach3 USB board V+ V- to my frequency inverter (type YL600-2s-2k20)? If so where? Will your upcoming (part 2)video deal with this as well as final connections for limit switches and stop button? Merry Christmas!

    Yes, the Mach3 USB board has two terminals that require 24V connection. Most VFDs have a 24V output that can be used to power this part of the Mach3 USB board.

    The V+ and V- on the Mach3 USB is not absolutely necessary to operate the CNC machine/router. The V+ and V- of the Mach3 USB board powers the outputs, inputs, and spindle's speed and control.

    Here is the Mach3 USB link for more information:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    The new YL600 VFD we have in stock may not have this 24V output. There is a 12V terminal, but I have not tested that terminal if it outputs 12V, or if it is a 12V input. If you are only conecting limit switches to the Mach3 USB and need to power that portion, 12V will be sufficient.

    I will delve into these aspects in far more detail on video.

    Thanks and Merry Christmas to you as well!

  • How can I convert from Xylotex to yours, four axis with limit switches. Have parallel PC and steppers on machine.

    Sure, the USB interface has a place for 4 axes of limit switches.

    Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

    A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

    Let me know if this information was helpful (or not) by adding information to this question. Thanks.

    User response:
    Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
    Thank you.

    buildyourcnc response:
    On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

    Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

    In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

    There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.
