what do i need to buy for a complete replacement 4 axis cnc mill nema 34 motors mach 3

If one or more motor is not responding, please follow the troubleshooting directions below:

For parallel Bob only! Make sure both the parallel and USB are connected.

Re-check wiring, and connections for continuity (no breaks in the wires) and check for correct wiring locations from driver to BoB.
Check dip switch settings on the driver.
Check components, by swapping the motors (ex. y-axis motor to z or x-axis driver and z or x-axis motor to y-axis driver) to check if motor functions on another driver.
Depending on software check step low active (mach 3) or invert pulse (planet-cnc) for the axis which is not responding.
Mach 3 - config/port & pins/motor outputs / Planet-CNC - file/settings/axes

I have an engine NEMA 34 from Y axis on my green bull that do not response, I already check connections and everything seems to be OK, how can I check that the motor it's working properly or not?

If you do not have electronics for your CNC, you will need stepper motors (or servos) that will fit your torque requirements, drivers for the motors, a power supply, applicable wires, and an interface board for computer communication. We sell electronic combo kits here https://buildyourcnc.com/electronicscombo.aspx

I just bought a 3040 800 watt cnc. What electronics do i need to buy to run it?

Make sure all your bolts/screws are tighten correctly and if using a lead screw make sure your anti-backlash nut is not offset. Now a default setting will be 10101100 for your driver dip switch settings and in motor tuning (mach3) 1600 steps per, 400.02 velocity, 4 in acceleration. now the acceleration and velocity can be adjusted to move your machine faster, but if set to high they could stall. Make sure you have the correct wiring from your motor to your driver (https://www.buildyourcnc.com/Documents/PN.SM60HT86-2008BF-U%20(inhouse%20PN.60BYGH303-13)%20(1).pdf).

I have your Nema 24 electronics kit and am having problems with the Z axis dropping over time. I am using a PC 8902 motor. Any ideas on what the problem is? What should be the motor tuning values in Mach3? Thanks

The available options for the blackFoot, is only structural components with hardware, and structure components/hardware with electronic components.
However we currently do not have any plans available for public use/distribution.

I have a 4x8 CNC and would like to cut my own parts for the Blackfoot. What is the price for the plans and the electronics ?

Yes, we offer a CNC electronics assembled package called the redFly, redLead and redSprout. If you already have a computer, I would recommend the redFly. You would still need to add connectors to the ends of your motor cable.

I need to replace the fried electronics box for my 6090 wood router. Do you offer a play and play, no wiring required, kit? If yes, how much? If no, can you recommend one?

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

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

Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

We recommend checking the dip switch settings on your drivers, having the correct microstepping/amp settings along with the steps/unit will help the motors run as effective as possible.
This is a default parameter that we use while we test our motors:
Driver dip switch settings will be at a 1/16 microstepping and 2.7amp (11001100) for x/y-axis and the z-axis will be at 1/4 microstepping and 2.7amp (10101100).

In planet-cnc with increasing the motor speed, you will have to modify the settings in planet-cnc (File/settings/setup) you will modify the initial speed, maximum speed, and the acceleration.
X/Y-axis step/unit: 1422.22 initial speed:500 maximum speed:750 acceleration:25
Z-axis step/unit: 1600 initial speed:100 maximum speed:300 acceleration:25
The initial speed and maximum speed will have to be roughly tested and adjusted per application.
Make sure to adjust the JOG slide bard underneath the axis controls on screen to about 750, to compensate for your x/y-axis adjustments. If left alone the speed will max out at the default setting.

Here is a video tutorial to calculate the steps required depending on your mechanical linear motion components. (

I bought Nema 24 motors and driver package with usb board. What do i need to have more speed? Cant even jog past 25 ipm without the motor stalling (not having enough torgue)

In regards to getting a complete plug and go system, there are a lot of items to consider.
Electronics, DYI or one of our electronics kits that come assembled and tested?
Cable for the motors is a additional purchase, spindle? = silicone tubing/water pump, etc.
Cable carrier (wire management), software (also additional purchase).

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?

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.

What do I need to purchase that doesn't come with the electronics packages?

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.
