The settings that will have to be change will be your steps per inch in motor tuning (mach 3), or settings/axes(planetCNC). But we do not have the actual numbers/specs that will fit your 10 TPI 5 start lead screw, here is a tutorial video which explains how to get the exact numbers you need! (

No, at this time, we do not offer any .dxf or any other type of file to cut the pieces for the DIY Combo #1. Just the directions that you are already able to access with the dimensions in them.

I can't think of any reason that it would be dangerous. However, I checked with the Cellular Telecommunications Industry Association. The Chairman of the Association sent the following memo on 18 June 1999, to the Associations' Board of Directors and others:
"You may have received inquiries about wireless phones causing fires or explosions at gas stations. In particular, you may have been asked about an alleged explosion at a gas station in Indonesia. We have been unable to verify any such occurrence in Indonesia or anywhere else. Moreover, in our discussions with Shell Oil they have stated they have attempted to verify these reports and also have not been able to document any such occurrence."
Nonetheless, in an abundance of caution, some manufacturers have included language in the owner's manuals for their products that recommends wireless phone users turn off their phones while at refueling points (gas stations). In addition, we have received information that Exxon will begin issuing warning signs at all domestic gas stations advising drivers to turn off all wireless communications devices when entering Exxon gas stations.

While wireless phone owners should always consult their owner's manual for information on the use of the phone, we are not aware of any incident that would justify these concerns."

If the laser tube is the same dimensions then yes, that tube can be implemented and take into account the required laser power supply and safety protocols on that high powered laser tube.

Our blackTooth is a fixed machine and is only made for the 40 watt laser tube that we sell.

Can we use a more powerful laser tube in the blackTooth? Say, 100w from ColeTech? Are they just physically too large/long?

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

Yes, it is feasible to create a machine with a cutting area of 13'x15'. Your mechanical and structural systems will need to be able to span a bit more than the 13' if that will be the axis travel along the gantry.

We have not cut carpet with our lasers, but I don't see why not. With that said, be extremely careful with the materials in the rug. Read the MSDS (Material Safety Data Sheet) for the rug you intend to cut as some materials will emit corrosive and harmful gases and chemicals when lased.

Hi I want to build a cnc laser table 13'x15' cuttting area. Is this feasible. Also would the 80watt laser be enough power to cut through carpet

A CO2 laser will not be suitable for cutting steel. You would likely need a very powerful fiber laser to cut steel, and even then you have to take into consideration the reflective properties of steel which can pose danger to the machine.

The best machine due to the width, will be the greenBull 5x which would have a cutting surface of 5' x 10'. Also our machines with spindle are accurate for 1000's of an inch, and can do 45 degree angle cuts.

Thank you for your feedback. Generally we are considered to be quite sane as a collective, although this can change from time to time.

We have a disclaimer on shipping rates, especially if you are ordering from outside of the United States, rates are generally shown only for air-shipments from USPS, UPS, and FedEX, which can be quite expensive. We do work with several freight and shipping companies that allow us to calculate options for lowering shipping costs. These companies do not generally have APIs that we can integrate into the website, so we need time to process quotes.

If the shipping quote you received from the website seems unreasonable, there is a good chance we can quote you a better rate. All you need to do is inquire with sales@buildyourcnc.com and we will make sure we get you the best possible rate.

are you out of your freaking minds with these shipping rates. About to go through with order but you lost me! Good luck!

The hub length of the drive sprocket and the other mechanical devise that is used to connect on the shaft will determine the length of the shaft needed for use with the drive sprocket.

The hub lengths for our drive sprockets are 1/2". So if you are connecting the drive sprocket to a motor, your motor shaft will need to be at least 1/2" in length.
