Question #: 13598

Question: If using a grease how does one protect leadscrews and rails from corian dust etc.

Current Solution

If you have abrasive particles in the air from milling, you will want to periodically clean the mechanical parts like the lead screw and anti-backlash nuts. After cleaning the parts, all of the high friction parts that will be in constant contact, lubricating the parts with oils, grease or other lubricants. If the part is of steel material, that material will definitely need to be oiled, greased or lubricated so minimal oxidation will affect the exterior of the steel parts.

The anti-backlash nut is made of Delrin, so petroleum chemicals like oils, grease or lubricants are ok to use. Abrasive particles may affect the anti-backlash nut over time; however, the spring and bushing of the anti-backlash nut will provide extensive use regardless of the wear.

    Currently our machines are made out of MDO (Medium Density Overlay) plywood, and are used in the construction industry for cement forming. They come lightly coated for moisture protection. Some possibilities for protecting the machine could be:
    Painting the structural parts with a oil based paint
    Coating the structural parts with a protectant sealant (polyurethane)

    Please try to avoid getting any coating or paints on the steel components.

  • Do you sell leadscrews and ballnuts that are 5 TPI? I'd like 0.001" per step, using a 200 steps/rev (1.8 degree) motor.

    We sell leadscews and anti-backlash nuts at the moment. Ballnuts will be available from us in the future.

    Specifically to your question, you want 0.001" resolution:

    The formula: (we are looking for a minimum of 1000 steps per inch
    steps = (motors steps)/(travel with one motor rotation)

    steps = (200 natural motor steps) x (microsteps ) / 0.5" travel (1/2" leadscrew 10 TPI 5 Starts)

    steps = 200 * microsteps / 0.5"

    multiply both sides by 0.5":

    steps * 0.5" = 200 * microsteps

    divide both sides by 200:

    (steps * 0.5") / 200 = microsteps

    replace steps with 1000:

    (1000 * 0.5") / 200 = microsteps

    500 / 200 = microsteps

    2.5 microsteps will provide .001"

    I would recommend 4 microsteps (1/4 microstepping), so your formula will be as follows:

    steps = steps/inch = (200 * 4) / 0.5" = 800 / 0.5" = 1600 steps/inch

  • Can you preset an origin point on this cnc? How long does it take to jog over? (If I have the case that I using the same thickness of maple wood, and same jig everytime)?

    Yes, you can preset an origin by zeroing the machine at the desired location before beginning your work. You can return to that exact point at any time, or you can specify an offset from that point to be the beginning point for the next machine operation (for instance when cutting several parts from one sheet of wood.) Jogging time varies by machine and application but would generally be a rapid move -- our default rapid setting is 400 inches per minute.

  • ARE THERE PRODUCTS AVAILABLE TO THE GENERAL PUBLIC THAT CAN BE PURCHASED PROTECT CELLULAR OR PORTABLE TELEPHONE USERS FROM RADIATION? IF SO, WHERE THESE FOUND?

    There are a number of opportunistic gadgets on the market to allegedly protect the user from hazards of cellular phones. You can search the Internet to find the latest, ranging from antenna shields to whole-body shielding materials. Most experts believe that these devices take advantage of customers' misunderstanding and unfounded fears to sell products with no real value. First of all, cell phones that operate within the guidelines established by national and international safety panels have never been shown to pose a health risk to the user (see answers to other questions on cell phone safety on this website). Secondly, placing any kind of shield over the antenna of a cell phone will in most cases cause it to increase its RF output as it attempts to compensate for signal loss in the shield and maintain a quality phone call. The U.S. Food and Drug Administration published an advisory on cell phones several years ago that said if you are concerned about risks of using a cell phone, then simply use it less. That is still good advice today. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory

  • HOW MUCH RADIATION GIVEN OFF BY A CELL PHONE AND THERE ANY WAY TO STOP THE FROM BEING ABSORBED INTO YOURSELF?

    Portable cell phones emit about 0.6 watts of radiofrequency energy, limited primarily by the power of the battery. As with any radiofrequency transmitter, there will be some amount of absorption in the human body; the amount depends on how close you are to the antenna. The Federal Communications Commission (FCC) limits the amount of radiofrequency energy which cell phones can deposit in the body to levels at which no health effects are to be expected. See an article on Cell Phone Safety on this website for more information.

  • USING MACH3, MY MACHINE STOPS IN THE MIDDLE OF A PROJECT. HOW CAN IT BE STARTED AGAIN FROM POINT STOPPED?

    Dealing with a mid-stop cut via Mach3, you will have to be careful if it is intentionally or unintentional. If you desire to stop your machine while in the middle of a cut be sure to stop it when the machine is moving in an upward motion on the z-axis and the X/Y-axis are stationary. Then you can choose the point (G-code) where the machine was left off and click on the Run from here button on the Program Run screen (left hand side) right above the Reset button.
    (Make sure spindle/router is running before hand!)

    Now if the machine stops unintentionally, and was moving in either the X/Y-axis, then it will be difficult to run the machine from the original point dealing with the coordinates might have been lost due the the machine continuing motion but via Mach3 the machine has stopped.

    If this occurs to fight this issue before hand, is marking your home with the spindle/router to make a hole were your home is. Although moving it manually back to home the machine can be off by the smallest amount and could cause an inconsistent cut. If accuracy is something that can not be risked, then you can home the machine about a 1/4" or 1/2" down from the original home to start your cut on the same material but loosing that small piece.

    Additional Information:


    Additional Information:
    My typical go to solution is:

    - Note the current g-code line where the machine stopped.
    - If Mach3 errored and you cannot control the machine, Exit Mach3 - you may find that reset, stop does nothing to stop the spindle. When you exit mach3, the spindle will stop automatically.
    - Restart Mach3. The DRO (Digital Readout) should show the correct coordinates where the machine position was before exiting Mach3.
    - Scroll to the g-code line where the machine stopped. You may need to go a few lines prior to make sure you are not skipping any machining operations (which is why it is a good idea to learn the basics of g-code - don't worry, it's easy)
    - Click on the "Run from Here" button.
    - Mach3 will present you with a "Preparation Move" dialog box with the location that it will move to. If the coordinates shows a position that is into the material, make sure to specify a rapid height (clearance height) so the machine will move up first and then move to the location before moving down into the material. If the spindle is automatically controlled by Mach3, make sure to check the turn spindle on checkbox. If not, make sure the router or spindle is on before clicking OK.

    My cnc router stops at gcode line 50,000 and cannot finish program. They are about 150k of lines total. I have Mach3 and have bought the additional line capability. Is 50,000 (or around that) the limit? Is Mach 4 hobby license better and in what ways? Thanks! Mike Huber

    Additional Information:
    If you have a license for Mach3, then you should be able to run g-code indefinitely. I think there is something else going on.

  • how do you calibrate steps per inch using Mach3 and a 1/2x13 lead screw

    You will first need to derive the number of turns per inch that your lead screw produces. If there is only a single start (typical all thread screws), then the turns per inch is the same as TPI (threads per inch). If there is multiple starts, then the number of starts is divided by the TPI to determine the turns per inch. For example, 10 TPI with 5 starts is 10 / 5 = 2 turns per inch. Now that we know this, we can get the number of steps per inch as described in the previous question: take the number of steps per revolution that the motor will output. This will be the number of full steps that you motor produces (typically 200, or 1.8 degrees per step) multiplied by the microstepping per step to which the driver is configured. Simply multiple the number of turns per inch and the number of steps per revolution and you will get the steps per inch. Ok, lets see the formula:

    200 steps * 16 microsteps * 2 turns per inch = 6400 steps per inch

  • From the BOB how can I reverse one of my steppers - i'm running 2 on my Y Axis

    When trying to use two motors on a single axis, there is a multitude of methods to get them to work together.
    First: There should always be a slave option in the CNC control software(mach 3/ planet-cnc/emc2/etc.), this will be the easiest way to make the dual motor configuration work. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.(Mach3/config/slaveaxis, planet-cnc/file/settings/axes).

    Secondly: Dealing with our interface boards(maybe third-party as well), you can have two drivers going to the same axis on the interface board. Which then will have one motor per driver, this will use the same motion and control from the (ex.) x-axis to driver two motors. However some adjusting might be necessary due to the orientation of the motor when mounting it on the opposite side of the CNC machine.

    Adjusting of the driver or motor wires, can be done separate from the control software with the use of a hex inverter, that can be used and to switch the signal (ex. takes a low signal and brings it high, and takes a high signal and brings it low) of one of the motors, to run the same as the other motor.
    There is also another method of inverting the orientation of the motors movement without the use of a hex inverter. This method you will have to wire the coil's of the motors oppositely of what is recommended for one of the motors. Example, you will wire our Nema 24 as follows(recommended): A+ - red/blue, A- - yellow/black, B+ - white/brown, B- - green/orange. However to run another motor with with it you will have to switch the A/B connections to: A+ - white/brown, A- - green/orange, B+ - red/blue, B- - yellow/black.

    These method's are usually needed/used when trying to control two motors and setting it up without the help of the CNC control software, and also due to the mounting orientation of the second motor, the inverting the direction of motion will be necessary so they work together instead of working against each other.

  • I would like to know if your breakout board and driver boards are compatible with MAC OS X working with Sketch Up pro using SketchUcam ?

    SketchUcam will output gcode which standard CNC control software will typically interpret, execute and control CNC machines. So, there is no problem using SketchUcam. However, our CNC machine control software that use our CNC machine interface boards require Windows OS, of Linux. The Mach3 USB board will only run with Mach3 control software which runs under the Windows OS. The parallel breakout board can run under Windows or Linux OS and the computer must contain a parallel port.

  • What resolution and level of repeatability can one usually expect from a kit-built cnc?

    Repeatability is very good for these machines and can be as low as .001" depending on the way you control the machine. If you use the spindle, you can be moderately aggressive, but you will want to use a finishing pass to make sure the edges are exactly what you would expect. since this is a kit, there will be varying levels of repeatibility depending on how well the kit is assembled and maintained. Calibration, as with all machines, is a critical aspect of keeping repeatibility over time.

    Timing belts and chain are about the same when it comes to precision as long as the chain wraps most of the drive sprocket. There are differences to each of these systems as Kevlar with steel cables impregnated within the Kevlar and the steel used in roller chain have different coefficients of linear expansion (the expansion and contraction over temperature change), and roller chain may stretch over time, so it is important to maintain the machine by tensioning the chain and timing belt, and calibrating the machine over time and when the temperature changes significantly.
