Question #: 1104

Question: Do you offer single shaft NEMA 34 steppers in your cnc kits?

Current Solution

Our NEMA 34 motors have a dual shaft, meaning, there is a shaft that extends from the front and rear. Our machines use this dual shaft motor in our machines. Currently we do not sell/carry any of these motors with one-input shaft.

  • Do you offer or can recommend a place where I can buy the Drive Pulley for NEMA 43 Stepper Motor (1586 oz-in 3/4" single shaft) 5.5 Amps?

    We don't offer those drive pullies with a 3/4" bore at the moment. We can supply them if you are willing to wait. If so, what is the pulley pitch, how many teeth and the width of the belt.

    Additional Information:
    Meant to say pulleys, not pullies.

  • Your combo kits don't specify whether they are standard NEMA motors. I need Nema 34 with a .375 shaft diameter. Which 3 axis kit work for these requirements?

    We currently do not have any Nema motor's with a .375"/3/8" shaft diameter. The motors in stock 100 oz, 425 oz, with a 1/4" input shaft. Our 651 oz, with a 1/2" input shaft.

  • Do your cnc machine kits include all of the components to make a working machine?

    Our kits include all of the parts needed to put a whole working machine together. However, understand that the kits are quite advanced and require a good level of mechanical competence to be completed correctly. We offer assembled machines for those that can't assemble these machines due to their complexity and need for fastening the overall components in a way that there is good smooth and tight motion, minimizing backlash to the fullest.

    We do have a few kits that you need to supply the table which include the greenBull 4x,5x and 6x, and the blackFoot. The tables would be far to large and heavy to ship. Our greenBull Kit is our best selling machine. All of the other machines are all inclusive.

  • Does your electronics combo allow 2 drivers on a single axis on the interface board?

    Yes, you can have two drivers connected to a single axis. If you want the two drivers/motors to work as a single, more concerted pair, then I would suggest connecting the two drivers to a single step pulse and direction signal.

    That is to say:
    driver 1 and driver 2 have wires connecting from the CP terminals of the drivers to a single step terminal on the interface board (USB or parallel breakout board), and the CW terminals of the drivers connected to a single direction terminal on the interface board.

    If the motors need to spin in the opposite directions, simply reverse one of the the motor A B coil connections (i.e. wires that would go to A+ and A- is connected to the B+ and B-, and the same with the B+ and B- to the A+ and A-). You can alternatively resolve this mechanically if desired.

  • I purchased your single relay and need to know what wire go s to the signal in

    Hi. The relay that we sell here:
    https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

    Has the same relay as the parallel breakout board:
    https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay

    And contains three terminals: "S", "P" and "P". The "P" is always connected and will be the connection between the "S" or the "O" depending on if you need the connection to be Normally Closed (NC) or Normally Open (NO).

    - Use the "O" if you need the connection from "P" and "O" to be Normally Open, meaning that the circuit will close (be connected) if the relay engages.

    - Use the "S" if you need the connection from "P" and "S" to be Normally Closed, meaning that the circuit will open (be disconnected) if the relay engages.

  • 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.

  • can your vacuum pump controller card work with a 1-1/2 HP single phase 200v motor?

    The relay on the Vacuum Pump Controller can handle up to 250V and 12A. If your vacuum pump falls below those values, then the vacuum pump controller will work.
