Certainly. The easiest way to process this and get you the correct item, re-order the new item and go ahead and send the mis-ordered item back with a note that you would like a refund for this order.

If time is not a factor for you but you don't want to be out-of-pocket, then simply send the item back (with a note that you need a refund) and you can re-order after the refund is made.

Hi Guys, I just received an order for some cable and realized the moment it arrived that I Miss-ordered. I ordered 8 wire instead of 4 wire. Can I exchange?

Yes, if the power supplies were supplied by us, we will exchange them with 110v equivalent power supplies.

Hello, I am a student working on a CO2 laser. We recently ordered two 40watt CO2 laser tubes and two 40 Watt CO2 Laser Tube Power Supply at 220V. However, our school is unable to use them due to being 220v. Is it possible to exchange these for the 110v supply, or is there a way we can go about connecting it at 110v instead of 220v? Thank you.

Roller chain in general is adjustable by using "master links", which are links which have horseshoe clip holding the pin and thus allow connections to be made or broken. The #25 is a designation of the type of roller chain. ANSI codes designate that the first digit(s) specify the pitch in eights of an inch, and the last digit is 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. So #25 is 2/8 = 1/4 inch pitch bushed chain with no rollers.

IS THE "#25 ROLLER CHAIN" ADJUSTABLE TO ANY LENGTH? LIKE IF I ORDERED TEN FEET OF IT, CAN MAKE TWO 3-FOOT LOOPS AND ONE 4-FOOT LOOP USING SOME SORT CHAIN JOINER?

Received the bluechick today. Inventory shows I am missing 1/4" bearing #339 and 4 each 1/4" set screws #360-10536. What do I do to get them replaced? Thanks. Lml

Have you considered reversing the A and B coils on one of the motors to the drivers? This will cause the motor to spin in the opposite direction. This is the easiest method. Using the HEX inverter is a more complex method and not recommended for simple driving tasks.

if you didn’t already, send an email with the cut lengths of the lead screw. If you did, then they will make sure to confirm before sending.

The email to send the cut lengths:
Phdroboticsllc@gmail.com or customerservice@buildyourcnc.com

Hi, I ordered some threaded rod yesterday and I wanted to verify the cut lengths.

We just received our new inventory of motors and that specific stepper motor ski came back with only one shaft. I’m not at the office to look at this inventory, so if that is true, they will all be single shaft. We may have other stepper motors with included rear shafts, but I will have to see on Monday.

If I don’t have the double shaft, we will provide a refund upon receipt of the motors. My apologies for this error.

Additional Information:
Hi, I'm sending these motors back today. As I understand you, you might have some motors from the previous lot still in stock, and these would be double shaft but otherwise you don't have any and won't be getting any. If you do have two double shaft versions of this motor please send them; if you don't have two of them please let me know--today if possible--so I can start looking elsewhere. Thanks, Ted Armen

we just received two nema 11 stepper motors per our order--USR2-2, however they are single shaft, we need double shaft, I thought that's what we ordered. We're sending them back, let me know if you do have the double shaft version and I'll try again to order them. I notice the model number on the motor ends in "A", where the packing slip shows "B".

Yes the CNC will do 3D wood carving and we can ship to Mexico. email sales@buildyourcnc.com for more information.

The greenLean machine comes with the entire structure and features a 4'x8' cutting area. You will still need some hookup wire to connect the electronics and silicone tubing for the water to and from the spindle.

greenLean Machine: https://buildyourcnc.com/item/cnc-machine-greenLean-v1

Thanks for answering my last question. So I have two follow-up questions from the response. The green leaf stands vertical is it designed for the material to be cut without falling free once it is cut through? And second question: you metioned water running to the spindle is this a cooling system for the spindle?

You would use holding tabs to keep the parts from falling out of the cut areas. Holding tabs are generated as part of the CAM file. Yes, this is the way the spindle is cooled. This is far superior to air cooling. Air cooling will blow the chips all over the shop.

I ordered the Mach 3 usb controller board on the 1st and I have not received an order conformation or shipping confirmation. My account was charged however.

You will need a USB cable to connect the computer and the Mach3 USB. The 64-bit operating system must be Windows and you will need the Mach3 CNC control software installed on the operating system.

You will need to install the USB driver called RNRMotion.dll. You can find the driver here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Move the file to your Mach3 Plugins folder Example: "C:/Users/ProgramFiles/Mach3/Plugins"

Mach3 will prompt you to select a driver and this is where you can select the "RnRMotionController" and check "Don't ask me again". This will allow your board to communicate with Mach3.

You will also need the xml file found on this page: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

On that page, you will need to download the XML Mach3 Config File by right clicking on the link and selecting "save as". Save the Mach3Mill.xml file in your Mach3 root folder.

That file is the main configuration file for the Mach3 board. It has all of the typical settings that the Mach3 board needs.

Cutting metals with a CO2 laser is nearly impossible with just the laser by itself, no matter what the power. The wavelength that a CO2 laser outputs is not best for cutting metals.

However, if you add oxygen as a cutting assist in the cutting process, metals can be cut, but we do not advise this as it is very dangerous.

What metal sheets can I cut with the 80W laser? What thickness, alumium, steel? What about the 100 or 130W upgrades?

From our records, you ordered Mach3. We purchase the license from the software developer and then we email you the license file that will be copied into your Mach3 installation.

Make sure to install Mach3 while you wait for the license file to be emailed to you.
