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.

  • 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.

    Additional Information:
    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.

  • 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.

  • 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.

  • HOW BAD IS THE SMOKE AND EXHAUST USING BLACKTOOTH?

    I'll be honest, it can be pretty awful at times. You'll want a dedicated exhaust line. Cut a new hole, make a dedicated line. Also, invest in a charcoal air filter, it will help. Trust me. They can also be done DIY very inexpensively. Buy a "Universal Pre-filter" and simply wrap it around a screen and have air push down through the screen wrapped in the charcoal laden felt. $20 + fan + screen. Away you go =)

  • Using your NEMA 24 stepping motor with microstepping, can I get a speed range from 3 RPM to 600 RPM ?
  • I get a "communicating unsuccessful" when using LaserCAD and the AWC608 Laser controller

    If you are getting the "Communicating Unsuccessful!" error when you are trying to communicate between LaserCAD and the AWC608 Laser Cutter and Engraver controller (after you have already tried installing the USB driver from the LaserCAD setup procedure), these are the steps you will need for a successful communication:

    - Open the Device Manager window (right click on the start menu and select Device Manager)
    - When you plug the USB cable from the AWC608 Laser Cutter Controller (USB Type B connector) to the computer, you should see a new item in the Device Manager, possibly under "Ports (COM & LPT)", or under "Other Devices". It may show as an item under "Other Devices", possibly FT245R and has an "!" in a yellow triangle.
    - Download the latest FTDI drivers from: http://www.ftdichip.com/Drivers/D2XX.htm
    - Unzip the files to a folder that can be easily browsed.
    - Right click on the item that appeared in the Device Manager when the cable was plugged in between the Laser Cutter AWC608 controller and the computer.
    - Click on update driver
    - Select the procedure to manually install the driver and browse to the folder containing the FTDI driver and follow the step in the driver installation wizard.
    - The item should now be located under the "Ports (COM & LPT)" and should be named "USB Serial Device (COM#)". The # will be the number you will use in the LaserCAD software.
    - In the LaserCAD software, click the "Select Mode" at the far top right of the Laser CAD user interface.
    - Make sure USB mode is selected.
    - If the Machine name with the correct COM number is listed, select it and exit the dialog window. Otherwise, click on "Add" and fill in the details with the new COM number.

  • 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

  • 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?

    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.

  • HOW CAN I DETERMINE THE DOSE EQUIVALENT (MREM/HR, MREM/WK, MREM/YR) USING RAW DATA FROM A TLD (THERMOLUMINESCENT DOSIMETER) THAT WAS PLACED IN AN OFFICE FOR 22 DAYS?

    Assumption 1: The "raw data" of 24 mrem on the TLD is the total dose received by the TLD during the 22 days that the TLD was deployed in your office. This means that (1) any TLD reader background signal has been properly subtracted, (2) the signal accumulating in the TLD during any transport or storage time between preparation (annealing) and deployment in your office has been properly subtracted and, (3) the signal accumulating in the TLD during any transport or storage time between removal from your office and processing (reading) has been properly subtracted.

    With this assumption, the total dose rate in your office is (24 mrem)/(22 days), or 1.091 mrem per day. The reference background is given as 63 mrem per year which is (63 days)/(365.25 days per year) or 0.172 mrem per day. Thus the average net dose rate to the TLD during the 22 days was (1.091-0.172) = 0.919 mrem per day.

    Assumption 2: The net dose rate of 0.919 mrem per day in your office is attributable to the accelerator or other regulated sources under the control of your institution.

    Assumption 3: The office occupancy factor of 1/4 attributed in your question to NCRP Report 49 was misread from Table 4. The correct occupancy factor given in NCRP 49 for offices is 1.

    Assumption 4: You take 20 business days per year off for vacation and holidays. You work in your office for the remaining 240 days per year.

    Assumption 5: All of the accelerator shots occur while you are in your office.

    Assumption 6: The average net dose rate of 0.919 mrem per day determined during the 22 days of measurement continues for a year.

    Based on the data that you provided and my assumptions, your annual dose received in your office from the accelerator or other regulated sources at your institution is predicted to be (0.919 mrem per day) x (240 work days per year) = 220 mrem.

  • 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.
