The installation of the motor inside the gantry is mounted and wired before installation of the back plate of the gantry. For Example, our blackFoot machine seen in steps(124/139), you can see that the gantry and and z axis is complete finished before back plate is placed.

Am I supposed to drill a hole in the back of the gantry to access the wires for the motor?? There does not seem to be a way to access the wires for the x axis motor once the gantry back is installed.

Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

[575] Hi, I have an old version of MACH3 V1.84 - Can someone tell me where to place the USB motion drive as there is no plugin folder in this version.

a 2' (24 inches) diameter workpiece for a 2'x8' machine may be a bit too much for an overhang. I would recommend the 4'x8' that can house a 4th axis in a cavity within the limits of the machine for a 24-inch part. If you need the rotary axis on the side of the machine, I can design a machine that would work.

[790] Is there a way to build a 2x8 flat cnc with a 4 th axis on the side so I can do 24” diameter objects. Or have the z axis that tall

Yes, you can use a corner plate very easily. You will want to make a corner plate that has three independent plates that do not conduct with each other. Each of these plates will be connected to a different input (i.e. IN1 for X, IN2 for Y and IN3 for Z). The end mill or tool that is inserted into the spindle will connect to V- of the 24V power supply, or the DCM on the controller, which is connected to the 24V V-. Then, you can use the ref all home button on the program run screen of Mach3.

Is there a way to use an X,Y plate that will only be responsible for corner finding in Mach3 with the Mach3 USB controller?

Currently we planned on having upgraded electronics with the whiteAnt 3D printer, which would have had the ability to support the heated bed, and other options. Which is why there was a configuration file in the downloadable files. However in newer developments we have been working on our prototype blackAnt 3D printer which will have the upgraded electronics and the option for the heated bed, but currently our whiteAnt cannot support the heated bed with the gen4 electronics supplied with the kit.

Whiteant- In the software there is a configuration for a heated bed. Where would I wire this in the kit's electronics if i bought one? Would the temperature be on/off or PID?

You would use a combination of bearings and collars to prevent your lead screw or rod from being able to move back and forth. Without it being able to move back and forth, you shouldn't have the couplings coming apart, because the motor is solidly mounted and unable to move as well.

I will try to draw a picture using symbols, with a key to define what each part is.

--CB|--------------|BC}{M

- = Lead Screw or Rod
C = Collar
B = Bearing
| = Wood, the frame of your machine
}{ = Coupling
M = Motor

On the example above you could replace the collar on the motor side with one half of the coupling, putting it right upside of the bearing to hold it in place instead. Like this:

--CB|--------------|B}{M

You could also place the bearings on the inside as follows:

----|BC----------CB|--}{M

can you please specify how to connect the collar/nut and bearings to prevent the axial movement of lead screw. Do I have to put that next to the stepper motor /coupling assembling or on the other side where the lead screw comes out. Or is there any way I can make the flexible coupling rigid so it does not come out of the middle spider?

I need wiring instructions for the breakout board you sent yesterday. It is not like the one in the videos and I don't know where to connect the 5V. No data sheet or anything.

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.

This is correct if it is the Mach3 USB controller. You will also get a rapid flashing led if you jog the machine (assuming the machine is not in reset mode or e-stop mode).

Portable cell phones emit about 0.6 watts of radiofrequency energy, limited primarily by the power of the battery. As with any radiofrequency transmitter, there will be some amount of absorption in the human body; the amount depends on how close you are to the antenna. The Federal Communications Commission (FCC) limits the amount of radiofrequency energy which cell phones can deposit in the body to levels at which no health effects are to be expected. See an article on Cell Phone Safety on this website for more information.

Yes, you will need a sensor to determine the speed of the rotation. For instance, you can use a hall effect sensor and put a magnet on the shaft of rotation. By installing the hall effect sensor near the shaft that contains the magnet, you can use this to determine the RPM of the axis and reflect this value in Mach3 using an input in your controller and setting that input in the index line item of the Mach3 input signals dialog box.

Here is a great video that shows the circuit and process:

You can set the Index input with Mach3 Turn and check that the Index is lit on the screen, but it is not reflected in the rotation speed. Is there any way?

Yes, you can absolutely communicate with the Pokeys57CNC controller. The developer's website has various ways of control, including their poblock software, or directly programming using C#, or C++. I have tested the C# method for a job I did for Lockheed Martin and worked really well.

[596] Hi there! Thank you for your great works. I was wondering if there is a way to communicate with this board using custom-developed software instead of Mach3 or Mach4.

The Planet CNC Software will require purchase after the trial version is completed, and will be purchased through their website. Currently that is the only software available for the USB Controller.

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

You can use grease, low-viscosity grease or oil. Your application may need to be considered.

Here is a document on the lubricating instructions from HIWIN:

The breakout board has a relay installed and uses the terminals labeled S, O and P. The following link explains the operation of this relay and how to connect the terminals:
https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/8/

You will run your power cord (use an extension cord rather than the actual power cord of the router) through the relay using the S, O and P. The P is a general connection and the S is normally closed (S and P is connected when the relay is not engaged) and O is normally open (O and p are not connected until the relay is engaged).

There are three wires in the power cord: neutral (white), live (black) and earth ground (green). You will run your neutral wire (white wire) through this terminal. At some point in the power cord, remove the outer insulator and expose the three wires within. Cut your neutral wire and strip both ends of the cut. Then insert one end in P and the other end in O (normally open), so Mach3 or other control software you are using will engage the relay and the router will turn on.

You will need to setup your control software to turn on the relay using Pin #16 as this is the digital signal pin that controls the relay.

You will definitely want to adjust your debounce setting in mach3 if your emergency or limit switch is engaging.
