A #6 screw will fit snugly in the mounting hole provided in the 1/2" Antibacklash nut. However, I would recommend tapping the mounting hole for a #8 or a #10 so you can create a jam-nut configuration.

[365] What is the diameter of the mounting hole? I'm not sure which size bolt to use with it.

No they will not come in that length as a default, we would contact the buyer to ask specific lengths due to the total length purchased.

However if you order the 1/2" lead screw we can get them cut to the specific length you require, by contacting us here or call us at 281-815-7701.

If I order 19ft of the 1/2" lead screw will it come in three 6'5" lengths by default? This is what I need. Thanks

The VFD does come with a manual that details the wiring and connection specifications, terminal features and a list of the parameters. There is no information on how to connect it to Mach3. It does detail the specifications within the parameters and terminal features on the analog input that is used with Mach3 and other control programs.

We do offer all of the parts; but it is best to purchase them a la carte. You will probably not want the hardware since this would not conform to a design in metal.

Our SBR20 rails use M8 bolts and are suitable for use with 8020 aluminum or any other common machine material. We suggest the use of our ball bearing pillow blocks with these rails, which you can find on our website here: https://buildyourcnc.com/item/mechanical-rails-linear-ball-bearing-block

What are the hole spacing dimensions for the Linear Guide Rail 20mm? I'm trying to figure out what size aluminum extrusion to purchase so I can mount these to it.

Here is a list of the parts needed to get the electronics combo functioning (parallel or USB interface options):

- 22 or 24 gauge stranded hookup wire to connect all of the drivers to the USB or parallel interface (terminal to terminal connections),
- 18 gauge stranded hookup wire to connect the drivers to the power supply,
- a power cable (extension cord) to connect from the power outlet to the power supply,
- 4 conductor cable to connect the drivers to the stepper motors,
- a USB cable to connect from the computer to the USB interface (or for power to the parallel interface),
- for the parallel interface, a parallel cable is needed (male to male db-25),
- a computer (for parallel interface, the computer will need a parallel port and if the computer does not contain a parallel interface, the motherboard may have a header for it, or you can purchase a parallel adapter to plug into the motherboard, very inexpensive),
- cnc control software: for the USB interface, you will need planet-cnc software, for the parallel interface, you can use any industry standard cnc control software (the typical is Mach3 for Windows, or EMC2 or Linuxcnc for Linux (Linuxcnc.org).

5v power supply is not needed. The 5 volts signal level power is derived from the computer through USB on both types of interfaces.

Yes, all of the spindles come with collets. The collets have a 1/4" (6.35mm) bore for end mills that have a 1/4" shank. The ER specification is different for the 1.5kW (ER-11) and the 2.2kW (ER-20).

I’M LOOKING TO PURCHASE SPINDLE AND VFD WAS CURIOS IF THE SPINDLES COME WITH COLLETS SO WHICH ONES?

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

There are several CAD/CAM programs out there for MacOS. Here is a list of a few: http://www.macuser.de/forum/f53/3d-2d-cad-395058/#post4499316
I've also read good things about punchCAD: http://www.punchcad.com/
Of course, there is always SketchUp if you are in a pinch. There are a few CAM plugins for SketchUp as well, but I've never used them, so I can't vouch for them.

CAD/CAM will get you as far as designing your parts and producing the g-code, but if you also want to run the CNC machine with your Mac, you will need a piece of software similar to Mach3 or EMC to run the g-code. I haven't been able to find anything like these programs that runs on Mac, so you may have to run Mach3 or EMC in Windows using Boot Camp or a virtual machine such as VMware or Parallels.

Personally, I would use the Mac to do all the CAD/CAM, then use a cheap PC to run the CNC machine.

When purchasing the 1/2" 5 start lead screw, the length is based on the quantity. Specify the total length you will need and we will email you (if you don't contact us first) to determine the cut lengths.

For example, if you desire 36 inches of lead screw for the X axis and 12 inches of lead screw for the Y axis, just purchase 48 inches of lead screw and tell us you need this lead screw cut so you have two lengths at 36 inches and 12 inches.
