### Question #: 3553

Question: Does the MDF have to be 3/4" or can you use Thinner sheets?

Current Solution

It's best to use 3/4" sheet for the scratch build machines on this site. There needs to be room on the edge of the sheet for an intersecting hole to meet the hole for the cross dowel.

• DO YOU HAVE BLACKTOE MACHINES WITH TABLES READY TO GO OR HOW LONG DOES IT TAKE MAKE ONE?

Yes, we have the optional table for the blackToe, but we need to fabricate it, which only takes one day. We generally reserve one week for the total fabrication and packing of all parts.

• MDF is slightly larger then 4'. Can the Blackfoot handel sheets of MDF (3/4" x 49" x 97")?

The sheets of MDF (3/4" x 49" x 97") will fit in the blackFoot since the cutting surface is 4x8, but the machine itself is a bit larger. However if you were trying to cut the entire sheet(edge to edge), the gantry might not be able to reach the extra 1".

• DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

• CAN .7MM END MILL BE USE TO CUT 15MM MDF?

An end mill smaller than 1.5mm or 1/6" is too small a diameter for end mills to cut through materials that are thick. A good rule of thumb is if the end mill has a cutting length that is more than what you want to cut, that diameter will be acceptable.

• HOW CAN THE ROUTER BE CONTROLLED OR CONNECTED TO ELECTRONICS COMPUTER?

The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

If you are interested in the USB breakout board, you will need to get an independent relay board.

• WHAT CAN ADD TO MY BLACKTOOTH LASER CUTTER MEASURE THE TIME OF USE?

Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

• Do you offer or can recommend a place where I can buy the Drive Pulley for NEMA 43 Stepper Motor (1586 oz-in 3/4" single shaft) 5.5 Amps?

We don't offer those drive pullies with a 3/4" bore at the moment. We can supply them if you are willing to wait. If so, what is the pulley pitch, how many teeth and the width of the belt.

Meant to say pulleys, not pullies.

• CAN I USE AN APPLE COMPUTER TO RUN THE CNC?

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
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.

• CAN JUST USE PARTICLE BOAD FOR THE SPOIL BOARD OR SHOULD MDX SOMETHING ELSE?

Well, I've never tried particle board. I would stay away from MDF since it is pretty terrible to breathe. You can use standard ply.

• I HAVE A 2000 WK 11–3 Z LIMIT SWITCHES GOING TO C10R10 BREAKOUT BOARD . CAN ALSO USE THEM AS MY HOME POSITION WELL. NEED THE WIRING CONFIGURATION

No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

I will answer the other question as another FAQ. Please check the Customer Service page to see the answer to that question.

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

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.

• CAN YOU GIVE ME SOME HELP OR POINT IN THE RIGHT DIRECTION TO INCORPORATE MK 7 EXTRUDER WITH BOOK PLANS FOR 3D PRINTER?

Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.
