Question #: 14384

Question: What precision do the CNC machine have, for instance the 12’’ x 36’’ x 3’’?

Current Solution

Our machine that matches those dimensions, the blueChick, uses roller chain for both X and Y axes, and a 1/2" 5 start 10 TPI lead screw for the Z axis. The precision is generally related to repeatability and we have not does extensive measurement of these tolerances. The resolution is set at better than 1000 steps per inch.

  • HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

    BYCNC response:

    Milling aluminum is no problem with our machines.

    Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

    The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

    For the dimension drawing of the anti-backlash nut, please contact us directly by phone or email to techsupport@buildyourcnc.com

  • WHAT CABLE LENGTHS SHOULD USE FOR THE BLACKFOOT CNC MACHINE

    The blackfoot requires a total of 50 feet of cable.

    The X axis needs 15 feet
    The Y axis needs 17 feet
    and the Z-axis needs 18 feet

    These are 20 gauge 4 conductor cable.

  • What is your shipping costs for the greenLean CNC machine to Perth Western Australia

    You can determine if the country is serviceable by:
    - selecting the items you want to purchase on the website
    - go to the cart (shopping cart top left of any webpage)
    - log in, or register
    - Enter the address and click on calculate shipping.

    The webpage will return the direct rates and whether your area is serviced or not. Feel free to enter any address as long as you are able to receive the package from that address.

    The shipping times are determined by the service you select in the shopping cart. If a machine is purchased, we generally have a one week lead time unless otherwise stated in the description of the machine's product page.

  • What size motor is powering the y axis on the greenLean CNC machine?

    For our greenLean CNC vertical machine, was built and controlled using 2 651-oz in motors/425 oz-in motor.
    The 651-oz motors runs both the x/y axis, as our 425-oz motor controls the z axis.

  • what do you mean by Kits , are they complete machines ready for use or prototypes to be followed?

    Our kits include all of the parts needed to put a whole working machine together. However, understand that the kits are quite advanced and require a good level of mechanical competence to be completed correctly. We offer assembled machines for those that can't assemble these machines due to their complexity and need for fastening the overall components in a way that there is good smooth and tight motion, minimizing backlash to the fullest.

    We do have a few kits that you need to supply the table which include the greenBull 4x,5x and 6x, and the blackFoot. The tables would be far to large and heavy to ship. Our greenBull Kit is our best selling machine. All of the other machines are all inclusive.

  • What is the Max thickness of wood that can be placed in the 4x8 cnc milling machine?

    Tricky question. That depends on the way the table is built. If the table is built with a step down area, you can put as thick a material as you want. If the table is flat, the clearance is 6 inches. Now, the thickness depends on the size end mill you insert into the collet. If you use an end mill that has a 2 inch cutting length, then your material thickness is 4 inches without a spoilboard. If you need to mill thick material, I would suggest that you fashion the table accordingly so the table can accomodate any thickness you desire. That's one of the great aspects of the buildyourcnc machines, adaptability.

  • What is the z-axis travel for your largest machine?

    The largest CNC machine we make at this time (12/04/2015) is the GreenBull 6'x12' model. This model has 2 options for Z-axis travel.

    The short-z option has a total Z travel of 5.75 inches. From that you would subtract the length of the end mill used and the thickness of the spoil board to determine the maximum material thickness. (Example: If the end mill extends 1.25" from the collet and the spoil board is .75", then the material could be up to 5.75 - 1.25 - 0.75 = 3.75 inches in thickness). This is good for most sheet-type materials.

    The long-z option, used mainly for large 3D carvings, requires a custom frame and allows for up to 36" of travel.

  • What is the best way to determine speeds and feeds for machine and bit longevity?

    The speeds and feeds are generally based on the amount of flutes that are being used per pass and how hot the end mill is getting when milling.  You want to use as much of the flutes as possible on single cuts.  Make the deepest cuts you can to increase the life of the tool.  For instance, if a tool that is 1 inch in cut length and the depth per pass is 1/4", then only that 1/4" is being used for the cutting.  The 1/4" tip of that tool will wear faster.  
    Make sure the feedrate is as fast as possible without a cost to the edge finish.  This will keep the end mill cool since there will be minimal friction as you are always cutting into fresh cooler material.  
    Use the end mill manufacturer's chip load for the tool to determine the starting feed rate.

    Feedrate (IPM - Inches/Min) = Spindle RPM x # of Flutes x Chip Load
    See each end mill for the chip load value.

    If your machine cannot achieve these feed rates, reduce the spindle RPM using this formula:
    Speed (RPM) = Feed Rate (IPM) / (# of Flutes x Chip Load)

  • What causes the cnc machine to stop/pause a second, or 2, in the middle of operation

    Did you look at the g-code instruction during the pause? There could be a dwell operation. Also, take a look at the status bar next to the reset button. There is information at that location that may be helpful.
