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

If the pdf. files cannot be viewed please update your pdf. reader, also for the X Table End, There are two of these table ends on the machine, each an exact mirror of the other. You will need six (1/4") 2" screws to fasten this to the two table halves. The two holes on either side of the bearing seat require 3" screws to fasten the motor mounts.

For specific requests with needed files (please state email address or email customerservice@buildyourcnc.com)

I am building the machine frome the book. The measurements for the 6 screws that hold the table together are missing. The chapter seven addisional material on the your website has the measurements but they are unreadable. Can you send me a PDF of that sheet. The cnckit1-1.pdf file on your website also is missing the measurements. Thanks Joe

It sounds like you got a misprinted book. If you purchased it from us, please contact us directly for a replacement. If you bought it from Amazon or a third party, you'll need to contact them. General information about lead screws is available on this website and at buildyourtools.com.

Just bought Build Your own CNC Machine book. It is missing the chapter on lead screws that is described on page 181 at the end of Chaprer 16. Where can I get this info?

Consider the loads on each axis when choosing appropriate stepper motors. If your holding torque is maxed out at roughly 16oz/in (1lb/in), then you could use the NEMA 11 or 14. Also consider the shaft sizes and current ratings when choosing drivers that pair with the motors.

I am planning to build a scratch CNC machine to do rotary engraving on writing pens. Can you recommend the parts I would need? I'm thinking NEMA 14 (11?) and 3/8" acme rod. Not sure which linear motion to use. I have an old lathe to use for the 4th axis.

Depending on the size of your CNC machine, it will vary the length required for your application.
Please verify the CNC machine, and we can go into detail on the specific lengths or methods for the linear guide mechanics.

Hi, this BBB comes with a USB port and its cable to power it up. Once connected to the computer a led in the BBB will light up to show it has power.

Additional Information:
Breakout board I have does not have USB port for the 5v power. Does the parallel port supply the 5V power?

Hi, I need assistance, the parallel breakout board I received looks different from the one on the video, does this one need a 5V supply? If so, where do I connect the positive and where do I connect the ground? Thanks for your help.

If your bearing does not turn anymore, it is possible to repair the frozen bearing.

You can carefully remove the shield on one side of the bearing. Use a very thin blade to remove the shield.

Once the shield is removed, use WD-40 or kerosene to wash out and clean any debris that exists within the bearing. WD-40 is a cleaner, not a lubrication agent.

You will then need to re-lubricate the bearing. Packing grease into the bearing will provide good protection not allowing too much metal on metal friction. There will be a layer of grease separating the ball bearings from the inner and outer races.

If you have a production environment, you may want to purchase extra bearings so that you will not have any down time.

If you have a rubber shield, just pry it out using any sharp object, like a utility knife. If your bearing has a metal shield, there may be a retaining ring along the outer race keeping the shield in place. Simply remove the retaining ring and the metal shield will fall out easily. If the metal shield does not have a retaining ring, that shield will not be able to be removed and a new bearing will need to be purchased to replace the frozen bearing.

You built the first 36 inch Blue Chick for me. One of the V-Groove bearings on the X-axis froze. Is there a method of repairing this? Or do I order another and a spare. If so, what is the procedure to repair or order?

The blackTooth laser power supply will use 4 - #8 x 1" screws, and 4 - #8 nuts. As stated on step 10 here (https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/10/)

I am building a blacktooth. I don't see in the instructions what screws are meant to fasten the power supply to the wood. The instructions show how to wire it but I don't see where it says which screws to use. I don't want to guess and end up being short later. Thanks. .

Just specify the full length in the quantity field in the shopping cart and give us a call to inform us of the cut lengths (you can also email customer service - link in the contact us page - link at the footer). We are working on a way to do this at the product page, but won't be finished for a few more days.

How do I order 3 specific lengths of lead screws in one order? I could only order a single total amount via the shopping process. I require 36", 60" and 14". If I order 110", I will get 79" + 31". Do I have to order 115" and pay for an extra 5" to get around this?

You need to either call us or email us, and provide the name you used when you ordered, so that we can find your order, as well as what parts you are missing.

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.
