Question #: 765

Question: What else to I need to purchase along with the "3 Axis Electronics Combo w/ USB Interface Board" to get the electronics up and running? (software, 5V power supply, 4-conductor wire, etc.)

Current Solution

Here is a list of the parts needed to get the electronics combo functioning (parallel or USB interface options):

- 22 or 24 gauge stranded hookup wire to connect all of the drivers to the USB or parallel interface (terminal to terminal connections),
- 18 gauge stranded hookup wire to connect the drivers to the power supply,
- a power cable (extension cord) to connect from the power outlet to the power supply,
- 4 conductor cable to connect the drivers to the stepper motors,
- a USB cable to connect from the computer to the USB interface (or for power to the parallel interface),
- for the parallel interface, a parallel cable is needed (male to male db-25),
- a computer (for parallel interface, the computer will need a parallel port and if the computer does not contain a parallel interface, the motherboard may have a header for it, or you can purchase a parallel adapter to plug into the motherboard, very inexpensive),
- cnc control software: for the USB interface, you will need planet-cnc software, for the parallel interface, you can use any industry standard cnc control software (the typical is Mach3 for Windows, or EMC2 or Linuxcnc for Linux (Linuxcnc.org).

5v power supply is not needed. The 5 volts signal level power is derived from the computer through USB on both types of interfaces.

  • if i purchase the 4 Axis Electronic Combos and the Combo #1 with hardware, plans and DVD what else do i need to have a complete cnc machine

    Other items you will need if you are purchasing the electronic combo (motors, drivers, power supply and computer interface) and the hardware and plans kit:

    You will need the wood to create the structure of the machine. You will need a router to serve as the cutting instrument. You will need a computer to control the machine and the software that will serve as the control program. You will also need lead screws and rails (aluminum angles). If you intend to have faster travel than 20 ipm, we recommend purchasing the 5 start lead screws so you can achieve up to 300 ipm. https://www.buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

  • Hello. I'm currently building my first CNC router, and I'm powering it with a 3 axis electronics kit that was purchased through your site. I chose to get the Mach 3 USB Breakout board, but now I'm wanting to try to use Linux CNC to work with the computer I have available. Will that work with this board?
  • If I purchase the [blackToe 2x4 v4.1 CNC Machine Kit - USB Electronics - Table Included] all I would need for this CNC to be fully operational is a laptop with mach 3 software and a router. Is this correct?

    if you purchased the USB interface, you will need planet-cnc software rather than Mach3, and you will need a usb cable to connect the usb interface to the computer.

    The blackToe 2x4 CNC Machine Kit with optional table will need wire to connect the electronics. Don't forget to get some end mills to use for cutting the intended material.

  • I recently purchased 3 axis electronics with the USB controller board. I'm trying to install an E-stop switch. Where do I connect that on the controller board?

    There are many ways to wire an emergency stop switch. The simplest, and arguably the most certain, way is to wire the switch into the incoming power so that throwing the switch kills all power to every part of the machine. Here is a diagram showing how a customer wired such a switch on their blackTooth laser which you could adapt to your needs. http://www.buildyourtools.com/phpBB3/viewtopic.php?f=12&t=4872

    Alternatively, you could use an input pin on your USB board. The wiring would depend on whether and how you might be using limit switches (single or multiple switches; normally open or normally closed). Our website datasheet for the USB board is at https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/ and shows how to configure the switches for each set up. If you use this method, you'd essentially wire the e-stop as a limit switch.

  • Looking to buy a black toe 2x4, what electronics are included ? Is it optional with USB-interface? And for last do you ship to sweden?
  • The electronics for my current cnc machine has a 36v 8.8 amp power supply. Is this power supply sufficient to power my new Mach3 USB interface?

    The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

    the mach3 usb interface can be found here:

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

    But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)


    Additional Information:
    The 36v 8.8 amp power supply we typically recommend is for powering the stepper motor drivers.

  • Is there a complete wiring diagram for the Medium Combo Kit with the usb board? Your USB tutorial does not cover the modular 2.5a drivers. https://buildyourcnc.com/item/electronicsAndMotors-3axis-100-elcombo

    We are currently getting it completed for us to post it under the 2.5A stepper driver page. However here is the correct wiring procedure.

    First: Wire the 24V power supply to the 2.5A driver, by wiring +V on the power supply to 12-24V on the driver. Next wire the COM on the power supply to Ground(GND) on the 2.5A driver. GND on the driver will also go to the GND on the USB board, for specific axis. (additional 3-4 wires connected to ground will be needed for the other axes as well).

    Second: Wire the USB board to the driver(one driver per axis on the USB board):
    CP on the driver will go to CP on the desired axis on the USB board.
    CW on the driver will go to CW on the desired axis on the USB board.
    5V will go to the VCC pin on the keyboard jog pins on the USB board (check schematic here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/).
    GND on the USB board to GND on the driver. (as specified in step 1).
    EN is not used.

    Personal Note:
    I would recommend that you crimp the VCC pin to a wire which could be split for the other axes as well, each driver will need 5V.

    Third: Wire the stepper motor to the driver, (using either the Nema 23 100-oz or the Nema 17 62-oz stepper motors, the wiring will be the same. For the Nema 23 the yellow and white is not connected.)
    Black to A1
    Green to A2
    Red to B1
    Blue to B2

    Fourth: Repeat steps 1-3 for each driver/motor per axis.

    Mention: Remember that GND on the driver will also go to the GND on the USB board for specific axis, and VCC pin on the USB board (keyboard jog) will go to 5V on all drivers for each axes as well, each driver will need 5V!

  • What would I need to purchase to increase the Z axis stepper motor up one size from the one that comes with the Blacktoe 4.1 with computer? I can't get Patrick to answer e-mails, so I'll try here.

    Thanks for the question. The blackToe z-axis motor is a NEMA 24 425 oz-in stepping motor and the next step up is a NEMA 34 651 oz-in motor located here: https://buildyourcnc.com/item/electronicsAndMotors-nema34-651ozin


    To make it work on the blackToe CNC machine, you would need to fabricate a new mount and the top bearing mount, or request us to fabricate it for you by calling the office.

    Curious, why the need to increase the size? If the motor is having a difficult time, there may be a deeper mechanical issue at play. One issue you may have is that the bearings are needing shim washers to separate the inner and outer races. If the two races are rubbing against the coupling or collar, the bearing may be difficult to turn under the weight of the assembly. If there is too much friction between the anti-backlash nut and the lead screw, you can add some 2-in-1 oil, or other similar lubricant.

    Thank you for using our Customer Service Live. Patrick often answers these questions. We prefer this system over email as these questions will benefit others.

    If you have additional questions or need more explanation relating to this question, please add to this answer.

    User response:
    I have added the shim washer between the bearing and coupling and have always used a light oil on the lead screw. I halved the acceleration on the Z-axis. Then I re-ran a topo that took two hours on the finish pass. No change in my results - the Z-axis slowly dropped until when the program finished and everything went back to the start point, the Z axis was lower by 0.378 inches than when it started at 0.800 above the surface.

    Any suggestions would be appreciated. Maybe I need more shim washers in the assembly between all the bearing surfaces?

    buildyourcnc response:
    Before you add a larger motor, check these first:

    1. take the motor off by remove only the motor screws and removing the motor as well as the coupling half that is secured to the motor shaft.

    2. Turn the lead screw by hand. This will still be connected to the z-axis assembly by the anti-backlash nut, so you will feel the resistance in the upward motion of the z-axis. Does it feel relatively easy to turn, or very difficult?

    3. If the resistance is relatively normal with respect to gravity and normal friction between the anti-backlash nut and the screw, then you may want to half the velocity as well on the z-axis motor tuning, and even reduce the acceleration a bit more. Doing topographical layouts should not require fast z-axis motor travel. Be careful not to lower the z-axis acceleration if you are using constant velocity as this can make the topo "too smooth" where there may be features such as cliffs present. If you need to lower acceleration drastically, then use exact stop rather than constant velocity.

    Another gotcha that may be causing this phenomenon is motor cable/wire chafing. We had this same issue crop up where two wires were shorting only at a specific position because the wires moved just enough to cause these wires to connect. This was caused by a zip tie. Zip ties have a very sharp edge that can cut the insulation of the wire. A hint of this problem is if this phenomenon is only present after working successfully with the machine for a greater period of time.

    Use response:
    I bought a new lead screw, bearings, antibacklash nut, and shim washers (WHICH NEED TO BE IN YOUR ONLINE CATALOG) and installed them. (Like another commentor on this site, my lead screw wouldn't go through the bearings. Simple solution was to chuck it into my drill press and 400 grit smooth it until a snug fit was had. Lowest RPM.)

    Anyhow, I ran another Topo yesterday and got the same results. The wires are not frayed, the acceleration has been halved, the speed reduced to a crawl. When testing manually, twisting the Z axis up was very hard to do compared to lowering it.

    I have thought about a counterbalance of some type, but that introduces lots of other problems.

    Anything you can thing of will certainly help.

    I can send pictures, etc.

    Thanks!

    What router/spindle do you have installed?

    User response:
    The one you sold me - 110 V, 1.5KW water cooled.

    User response:
    This problem of the z axis drift has been evident since I first started using the machine a couple of years ago. Lithophanes, stipples, topographic and other heavy z axis users have been particularly bad. It is to the point that I am turning away opportunities for lack of capability.

    Buildyourcnc response:
    I think all options may be exhausted. We will design a new mount that holds a large motor. Please give us a call so we can arrange to send that out to you.

    We just determined that the existing mount need to be adjusted by about one millimeter for the main mounting hoes for the larger NEMA 34 motor to fit. The overall mount will look the same but the outside hole spacing will be adjusted by a very small amount to match the larger motor mounting holes. This new adjustment will be included with all new machines. We will send you the new mount (consisting of two structural pieces) and the longer screws that will be needed to extend to fit the motor frame thickness.

    Additional Information:


    Additional Information:
    They didn't send the longer screws, nor the new required coupling, but I finally got it together and it works just fine. It returns to precise Z zero every time.

    But the motor runs pretty hot because I think it should be run at a higher voltage than the current power supply provides.

    Any new sales of Blacktoe 4.1 should include this modification.

    Cheers.

  • Looking for electronics for a plasmacam table. It's going to to be a 5'x10' table with x,y,z axis. Will be running on windows ten with a hypertherm powermax45 xp plasma cutter. Any information or links would be greatly appreciated!

    What electronics do you have at the moment? Depending on your machine, you will need a minimum of 3 stepper motors and 3 drivers (unless your heavy axis requires two stepper motors and two drivers). You will also need an interface board that is capable of providing three inputs for the THC (Torch Height Controller), THC on, THC up and THC down, and outputs for firing the torch. I would recommend the Pokeys57CNC interface for the primary interface. This interface will connect to the stepper motor drivers and the THC. The Pokeys57CNC can also communicate via USB or Ethernet.

  • Going to purchase a new laptop computer. Question. What is the minimal requirement for laptops running cnc planet software and other softwares that are needed?

    Your purchase of a laptop will depend on what CNC software and CNC interface you will be using. In most cases, CNC interfaces use a parallel port, or the interface will convert USB instructions into a form of parallel I/O pins. We provide both types of interfaces, but you will be required to use specific software packages compatible with the interface. The USB interface that we sell at the moment is only compatible with Planet-CNC software (which is very good software), and if the computer has a parallel port, you will have your choice of many software titles including (but not limited to) Mach3 and LinuxCNC.

    The hardware and processing performance is not as important. Computers with relatively slow processors (i.e. Pentium) can control a CNC machine and achieve good performance.

    If you intend using CAD and CAM on that computer, then you will want a more modern computer that will have a good amount of memory and processing power. You will need to refer to the software requirements for the minimum specifications.
