I am interested in buying the greenBull 5X Long Z CNC Machine Kit, but it is not clear for me what is included in this kit. Is there anything else I need to get the machine work?
The greenBull 4X comes with all of the components and electronics to assemble the gantry of the machine. You will need to build the table. We provide the rails and roller chain for the X-axis (along the length of the table for full 8 feet of travel). You will need to provide some wire to connect the electronics and a computer to run the machine. You will also need to purchase the software that you will need to run the machine that matches how you will apply the machine. We suggest the mach3 control program. The CAM program is up to you as there are many options out there.

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 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:

I ordered the GreenBull 5' x 10' kit. The first video for assembly shows that I should have 5 large boards that attach to the table, but I don't have those boards. Is that something I need to build or were they not shipped?
We apologize for the confusion, however in the very first video that is regarding the assembly, is of the torsion box. We do not included that in any greenBull kit, as we use too sell it individually! However due to high consumption of materials and high cost(both in shipping and for the kit itself) we have removed it from our inventory and no longer sell it.

This video can be skipped, however if you plan on making a DIY torsion box, this video will be helpful in your build!

The torsion box is not needed, as the frame itself will be more than sufficient in keeping the machine from flexing or vibrating.

Hey Patrick where is the video to adjust manufacturers parameters on lasercad? I watched it but can not re-find it. For pulse unit
The latest LaserCAD video that I have is this one:
https://www.buildyourcnc.com/tutorials/tutorial-trocen-anywells-lasercad-install

I go over adjusting manufacturers parameters at the end of the video.

Do you remember another video other than this one?

Additional Information:
I also have a video where I calibrate each axis. I go deeper into the manufacturers parameters in this video:

Let me know if this helps.

Additional Information:
I seem to remember one where you did an actual physical measurement to work out the new parameters. Basically the file I put in is coming out much bigger than it should. Also, whenever I reset the settings and put the same values in to double check, it changes them again.

Additional Information:
I think the one I just added to this question is it. You may have been writing your response while I was adding this video.

Additional Information:
Yes that is the one. My settings should be very similar to yours, yes?

Additional Information:
Yes, it will be similar but not exact. If the microstepping is different than mine, the value will be totally different, but that is fine. As long as the nozzle goes where you expect, you will have good X and Y axis values. Remember to do the calibration with point as far apart as possible. That will make the overall calibration much more precise.

Additional Information:
The file is still coming out bigger than lasercad says. Says its 65mm and its about 3 times that. Also, X axis is a little joggy again.

Additional Information:
If the travel is 3 times farther, then it's going to be 3 times faster as well, so the motor has reached it's speed limit. The value is in steps/mm, so if you divide the value by the manually, see what happens.

I have a breakout board and it appears that the pin 12 connection has failed: when i move my limit switches to pin 11 they work; they don't work on pin 12. Do i need a new breakout board?
For safety's sake I would recommend a new board because they are inexpensive compared to the electronics that they support. Alternatively, it's possible that the one dead pin is a simple fix, such as a bad connection or solder joint; if you feel comfortable making those repairs then it could be worthwhile to check. Finally, if you are not using all the input pins, you could continue to operate the limit switch on pin 11 and hope for the best.

Can anyone tell my the exact center to center mounting hole distance on the 20mm linear guide rails? I have done some measuring but I am afraid they vary.
The 20 mm linear guide rails have a hole distance from center to center of 60 mm.
The 20 mm round rails have a hole distance from center to center of 150 mm.

Mach 4 is not triggering PWM pin 17 on Pokeys57CNC. I am able to get it to work through the Pokeys app but not Mach 4. I've made all of the setting changes prescribed in the manual.
I will check with the developer of the board and show the response on this FAQ.

Additional Information:
The response from the developer:
Are you referring to using Pin 17 for the spindle speed control? Make sure that you set the desired spindle speed in Mach4 by executing S1000 in the MDI or the G-code.

I bought a 1.5kw spindle that came with the ER11 6mm collet. I found collets for 1/4" and 1/2" but will these work with my existing nut? I see there is a nut for sale but it says its just for Bosh and Porter Cable etc.
It is likely that if your Spindle's collet is ER11 specification than other size ER11 collets will work with your spindle.

I'm assembling the gantry for a 5x10 greenbull and noticed that there are 9 spaces for torsion spacers but only 7 in the kit. Should I just space them out on the right side behind the motor?
That is correct. We send the fewer ribs than could be fastened within the gantry. One reduction of a rib will provide more space for the motor at the midpoint of the gantry and at the other side of the gantry (opposite the motor) can be reduced to provide more space to work with the coupling.

On the pokeys57 board should I use the limit/home plug or just the block next to that plug form setting up home proximity sensors? I have them on the plug now and can not get them to work.
For setting up home proximity sensors on the PoKeys57 board, it's typically recommended to use the designated limit/home terminal or pin. This is because these ports are specifically designed for connecting limit switches or proximity sensors used for homing.

If you've already connected your sensors to the limit/home terminal and they're not functioning properly, here are a few troubleshooting steps you might want to consider:

Check Wiring and Connections: Ensure that the wiring to the sensors is correct and secure. Sometimes a loose connection can cause issues.

Sensor Configuration: Verify that the sensors are properly configured in the software you're using to interface with the PoKeys57 board. This could involve setting the correct sensor type (NPN or PNP), and ensuring the software is looking for the homing signal on the correct pins.

Test Sensors Individually: Disconnect other inputs and test each sensor individually to isolate the issue. This can help determine if the problem is with a specific sensor or the board itself.

Firmware and Software Updates: Ensure that your PoKeys57 board firmware is up to date, and that you're using the latest version of the control software.

Is there a specific process for aligning the x axis on the greenbull? There is mention of it at the end either the rail or gantry installation but I could not find it anywhere.
If you are referring to aligning the rails so that the rails are perfectly parallel:

It is important to make sure one rail (a rail at one side of the table) is perfectly aligned first. Do this by fastening one end of the rail to the table (flush with the table edge), then fasten the other end (flush with the table edge). The rail may not be perfectly straight at this point, but that's ok. This process includes the top and bottom rail, fastening and positioning simultaneously.

You are going to fasten the midpoint of the rail. Get a clamp ready so that you can freeze the rail in place. Look down the rail from one end. This is a good way to determine if the rail has a curve, or is straight. If there is a curve, move the rail midpoint laterally until the rail is straight while looking down the rail from one end of the rail. This may take a couple of people to do, one looks down the rail, the other moves it slightly until it is straight and then clamps the rail. Drill and fasten the midpoint when satisfied. Repeat this process, fastening at the midpoint between screws.

Now place the gantry on the table with the v-groove bearings resting on the one rail side. Add the next rail to the other side of the table. Position the rail so that it is directly under the other bearings. Make sure the gantry is at the extreme end and fasten the rail at that end. Move the gantry along the and fasten the rail as you move the gantry so the rail auto-positions itself.

Additional Information:
Thanks for your answer. So the next step is making certain that the gantry is exactly perpendicular to the x axis. Do you just place a square on the rail and adjust one or both chains as needed?

How do I wire up multiple E-stop to breakout board, does each E-stop need there own pin? If not since there are only 4 screws on stop 2 for no and 2 for nc do you just splice the wires together if your only using 1 pin? Thanks

It appears I have a connection issue with the USB port on my computer with the USB cord. I purchased a new cord but has the same issue. Is there anything I can do to correct this issue?
Is this CNC related. If so, what controller are you using?

Additional Information:
I'm using the Mach 3/USB CNC interface board, with the Mach 3 software.

Additional Information:
Does the LED on the controller light up, or blink?

Additional Information:
I believe I've corrected the issue. I found that their are 2 spring like tabs on the female USB port. And take a sharp point like on a compass and gentle raise those tabs a bit. This tighten up the connection, and I never received an error from losing connection.

I installed the USB CNC Planet and got out of your USB controler $ 75 .Viska have linked to a video 'Party - 2.. X - running and y and z-axis does not work, it moves step motors and controller positions X -axis works, and Y and Z does not work.
Recommend first test to check a non-working axis, is to connect the current working axis(ex X-axis) to either the y/z axis to test the actual board and wiring in other axis setup. If tests failed and working (x-axis setup) does not working in the new axis location, go the Planet-CNC/File/Settings/Axes and check if your current non-working axis setup requires a inverted pulse. Check box and test again.
Next test if first fails, is to check continuity in your wires. A simple multimeter(ohm's) will work, just connect the positive and negative ends to one side of the same wire and if reading comes to 0.000, wire has continuity and if reads 0.L then there is a break in the wire and should be replaced.

bluechic v4.2 - mach3 setup video does not play on the metacafe site... since I'm new to this I am lost on how to configure mach3 to the usb breakout board. Please advise, thanks!
To setup mach3 for the parallel breakout board, view the last three videos on this page:
https://buildyourcnc.com/CNCElectronicsandWiring.aspx#prettyPhoto

The parallel breakout board contains a usb connector, but is only used for power. The USB interface board (sold here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout) does not use Mach3, rather it uses the planet-cnc software.

ON THE BOB...EVERYTHING TESTS OK BOB EXCEPT X-DIRECTION OUT. IT'S VOLTAGE IS SLIGHTLY DIFFERENT THAN Y AND Z (5.00 INSTEAD OF 5.03. TESTED X DIRECTION ALL THREE DRIVERS. IN EACH CASE THERE GOING INTO DRIVER BUT NOT OUT IT.
The electronics can be tricky sometimes, especially if more than one change is made for a test. You can move the x-dir wire to another pin and set it in the software configuration. If it works, then only that pin is bad.
