  • 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.

  • What side of the x and y axis do you mount the stepper motor to? If it does not matter what side, do I have to change something in mach3?

    It is usually best to mount the motor in a way so it is spinning clockwise to avoid confusion.

    Additional Information:
    ok, but lets say the motors turn clockwise. if you mount it to ether side of the y axis it will pull to that side so what are the correct positions of the stepper motors. is it the left side or the right side of the y axis and also is it the front or back of the x axis?

  • I have a BlackFoot with a 3.25hp Porter Cable router. What is a safe starting IPM to optimize feed rate? How fast do you guys run full depth passes through MDO or MDF?

    It is not recommended that standard routers do full depth passes. This is better done with a spindle. For best results with routers, we recommend a depth that equals the cutting diameter of the end mill. The IPM will relate to the chip load of the end mill (look up the formula online and add it here). The IPM will also depend on the end mill diameter, the larger the diameter, the faster the feedrate. A 1/2" end mill can cut about 300-500 ipm where a 1/4" end mill will be able to cut at 80-120 IPM, at a depth equaling the cutter diameter using a router. With a spindle, the same feedrates can be applied, but with more depth per pass. For instance, an MDF full depth cut at 3/4" can be cut at the 100 IPM using a 1/4" cutter.
    Here is a basic setup we have for our blackFoot (default setting):
    X-Axis
    SPI: 914.29
    Acc: 400.02
    Vel: 5
    Y-Axis
    SPI: 1422.22
    Acc: 400.02

    Z-Axis
    SPI: 1600
    Acc: 400.02

  • I just made the book build Cnc machine with the feed rate of 11.19 inch/min as suggested in book. Can I increase it to 20 inch/min? I have 2hp of router attached

    The book (scratch build) will be able to cut at very high rates of speed, but the speed is partly determined by the mechanical setup. Cutting wood is generally recommended between 60-200 ipm depending on the end mill and spindle being used. The larger the end mill (with increased chip load capacity) the faster the feedrate.

    If you are using a standard allthread, you will not be able to have these high feedrates. You will need to purcahse high lead leadscrews: https://www.buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

    The stepping motors need to turn 13 times to travel one inch using standard allthread (1/2-13 TPI - threads per inch). The higher lead leadscrews shown in the link provided will move one inch with only two turns allowing the machine to move many times faster.

    These speeds are especially important if you are cutting materials that have low melting points like aluminum and thermoplastics like acrylic, Plexiglas, etc. These materials require high feedrates and smaller depth per passes.

  • My computer doesn't have a parallel port connection. Can I use a usb to parallel port cable to communicate with my breakout board?

    A parallel to USB adapter will not work. You will need to use a USB interface like the ones below:

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

    Poeys57CNC Interface:
    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

    Additional Information:
    To answer the question in more detail, the parallel port is actually an extension straight from the CPU and is also called the GPIO (General Purpose I/O) pins. These pins carry signals independently, hence the description as being a parallel port.

    The stepper motor driver receives a pulse train (series of pulses). A single pin on the parallel port sends a pulse train to one stepper motor driver and stepper motor for a single axis. Another pin on the parallel port sends a pulse train to another stepper motor driver on another axis. This happens simultaneously as with the direction signals for each axis.

    If a parallel port is adapted through a USB (using an adapter), the parallel port cannot have these signals happen in a simultaneous fashion and will cause the stepper motors of a CNC router or machine to be very clunky, if it works at all. To elaborate, the computer sends an instruction to the USB to send a high signal to pin 1, so it does, then another signal to pin 2, so it does. This is happening one after another. The speed at which this happens is reduced dramatically, and the position of one axis may now be out of sync to another axis.

    The reason the USB interfaces (linked above) work is that the USB delivers broad instructions to the interface (to a microcontroller) and the interface parses the instructions and outputs simultaneous signals to the stepper motor drivers.

    Hope this helps.

  • I AM PUTTING TOGETHER THE BLACKFOOT AND USING A PORTER CABLE ROUTER. CONFUSED ON HOW TO RELAY ROUTETR WITH USB BOARD. IS THERE ANOTHER SWITCH THAT GOES BETWEEN BOARD ROUTER SO PLANET CNC CAN TURN PERHAPS VACUUM OFF?

    We are currently working on a relay board that will connect to USB breakout board, and the router/spindle for both the on/off function. Unfortunately we still do not have it completed or ready to be placed on our website, but it is in the final stages of testing. Please check back regularly for updated stock!

    Here is a link to a tutorial for a DIY relay circuit:



    There is no vacuum control on the Planet-CNC program, however you could use the same concept of the router/spindle on/off using the relay circuit. Although you will have to use either the flood or mist function for the vacuum.

  • Is it possible to increase the Z axis on the Blacktoe 2x4? My ideal would be to have 8" of travel.

    Increasing the size on your Z-axis is possible by making the over z axis longer (rails, wood structure). Remember the location of your router/spindle and over all integrity of the z-axis structure.
    Now another way of getting a longer reach is making a adjustable height table, so that you can raise or lower the material section(2' x 4') to add taller material or get a deeper cut.
