  • HOW SERIOUS A PROBLEM INFLUENZA (THE FLU) IN THE U.S.?

    Influenza is the most frequent cause of death from a vaccine-preventable disease in the United States. From 1990 through 1999, an average of approximately 36,000 influenza-associated pulmonary and circulatory deaths occurred during each influenza season. In addition to fatalities, seasonal influenza is also responsible for more than 200,000 hospitalizations per year. Rates of infection from seasonal influenza are highest among children, but the risks for complications, hospitalizations, and deaths are higher among adults ages 65 and older, children younger than 5 years, and people of any age who have medical conditions that place them at increased risk for complications from influenza.

    A novel H1N1 virus was first detected in March of 2009 and quickly spread to pandemic levels. In the U.S., it is estimated that approximately 43-89 million persons became ill with 2009 pandemic H1N1 from April 2009 to April 2010. The virus also resulted in significant hospitalizations and deaths among children, adults 19-65 years, obese persons, and pregnant and post-partum women.

  • What's the difference between the redLeaf and redSprout?

    The redLeaf uses a standard motherboard with a reasonably fast processor that can control the CNC machine and run CAD and CAM applications. The Hard drive for the redLeaf is 1 TB.

    the redSprout uses a miniITX motherboard that contains an Intel Atom of equivalent processor. This configuration is adequate for controlling a CNC machine however, CAD and CAM programs may run slow. The hard drive is either a 500GB or 60GB SSD. The overall size is smaller than the redLeaf.

    Both systems come with 2 GB of RAM.

  • WHAT'S THE DIFFERENCE BETWEEN PARALLEL BREAKOUT BOARD AND USB ITERFACE?

    The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

    The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

    The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

  • What's the difference between 128 microstepping and 1-1/64 microstepping?

    I'm not sure what particular devices you're talking about so I can't help you as far as compatibility goes, but a microstep fraction refers to the resolution of the rotating motor. let's say your motor takes 200 whole steps to make one complete revolution of the spindle. If you then set your motor to run at 1/64 microsteps it would mean your motor is taking 64 times more steps to cover the same distance, making a total of 12,800 steps to make one complete revolution of the spindle. So a smaller fraction of steps like 1/128, would take even more steps to complete one revolution, 25,600 in fact.

    If you're talking about motor drivers it's probably telling you how many options of resolution you have.
    one giving the highest resolution of 1/128 microsteps but probably still capable of doing 1/64, 1/32, 1/16, 1/8, 1/4, 1/2 and 1 whole step.
    the other one that says 1-1/64 is telling you it ranges between 1 whole step and 1/64th microsteps, so you could do the fractions between like 1/32, 1/16, 1/8, 1/4 and 1/2 as well.

    The amount of microsteps you want to make in one revolution is totally up to you, more steps potentially means a more precise machine, but at a certain point the extra steps may be unnecessary.

    hope this helps

  • What's the difference between 128 microstepping and 1-1/64 microstepping?

    Stepper motors are designed to move in specific increments; these increments are called "steps". For example, a common standard is for 200 steps per full revolution. Microstepping is a method to send signals to the motor to move only a fraction of a full step at a time. For example, if a motor has 200 steps per revolution and is microstepped 1/16, then effectively there are 3200 small step movements (microsteps) per revolution instead of 200 larger ones. This makes the motion of the motor much smoother and more precisely controllable, at the cost of decreased holding torque.

    Here are is a good references for stepper motor theory: http://users.ece.utexas.edu/~valvano/Datasheets/StepperMicrostep.pdf

    And Wikipedia has a good overview as well:

    Therefore, the difference in 128th and 64th microstepping is increased resolution and smoothness for 128th microstepping, at the cost of decreased holding torque.

  • What's the maximum speed at I can machining reliefs without lost steps with BlueChick?

    This will depend on the material, end mill that you are using, and whether you are using a spindle or a router. The stepping motors and the mechanics on the blueChick (and the other machines as well) can move the machine very fast (x and y about 700 ipm rapids).

    You will need to refer to the manufacturer specifications for the speed on the end mill with the particular material. The Onsrud end mills sold here are of top quality and can generally go faster than standard end mills. If the reliefs are in wood, you will be able to machine around 200 to 80 ipm depending on the wood and the depth per pass. Generally, you want to rough out most of the wood with a roughing end mill then finish off with a finishing end mill with a small tip and a small step over.

    If you are using a router, the speeds will be slower than a spindle since the spindle can handle more torque and the torque is compensated with the VFD (Variable Frequency Drive).

  • THE DUST SHOE HAS STIFF BRISTLES, IS THERE PROBLEM WITH MOVING Z-AXIS DOWN SINCE BRISTLES PUSH AXIS SIDEWAYS

    A couple things to consider, the machine is most likely moving sideways, so the bristles won't be a problem. The lead screw has a very hight mechanical advantage and the bristles don't pose an issue with this. We have not found that the bristles cause any appreciable deflection to the work we do in our shop; however, you can change the brush for a more pliable plastic, or reduce the number of bristles by selectively pruning.

  • What's the cost of a Bluechick 4.2 with computer ready to go shipped to Reno NV. porter 892 set up.

    The price for the blueChick is here: https://www.buildyourcnc.com/blueChickVersion42CNCMachineKit.aspx

    You will want the kit without electronics that will cost $1360.00.

    Then you will need either the redSprout, or redLeaf CNC computer systems and the prices can be found here: https://www.buildyourcnc.com/AssembledElectronics.aspx

    The redLeaf has a bit more power and speed than the redSprout. You will need to purchase windows, found on that page, if you desire that OS to be installed. Otherwise, we will install Linux and linuxcnc. You will also need to purchase the length of motor wire that you need from the motors to the computer. This is variable and is determined by the position you wish locate the computer system with respect to the CNC machine.

    The shipping is determined at checkout. When you have the items in your cart, enter your shipping information and click on "calculate shipping". You will need to select your shipping preference, service and carrier.

  • Anyone having a deflection problem with onsrud compression 1/4 bit

    We can't speak to the specific endmill you are using, but can provide some general information about tool deflection. In general, anything that increases rigidity of the cutter will minimize deflection and vice versa. Mathematically, deflection is directly proportional to the cube of the length divided by the fourth power of the diameter.

    Practically speaking, with all else equal, cutter diameter will have the largest impact on deflection (bigger being better), followed by stickout (the amount of cutter extending past the collet) which should be minimized, and finally number of flutes (fewer cuts in the metal = more rigidity).

  • My Z axis stepper is "cogging," new problem on an older machine, any solutions?

    If by cogging, you are referring to the lack of torque by the presence of the lack of current to the motor, I would check the wires coming from the motor to see if there is any chafing, causing either shorting, or a connection issue. This happens on older motors due to the method of holding the wires steady using zip ties or other form that can cut the insulation of the wires. If you see this phenomenon only at specific locations on the axis, then wire chafing could be the culprit. But, can also be friction on the lead screw/anti-backlash nut.

    Check the anti-backlash nut for any presence of oily debris. Remove this debris and re-lubricate the lead screw.

    Check between the coupling at the motor shaft and the bearing that is positioned against the coupling. There should be a small outside diameter shim washer between the coupling and the inside race of the bearing. If there is no shim washer, then the coupling is rubbing against the outside race, causing friction, or binding.

    If these methods do not work, please submit additional information on this FAQ page using the additional information button and a new solution will be submitted by us.

    Customer response:
    Thank you for your quick response. I found the Z-axis binding with the anti-backlash nut. What would you recommend to lubricate the anti-backlash nut and lead screw?

    Additional answer:
    I would recommend using 3-in-1 oil to lubricate the lead screw and the anti-backlash nut. Don't worry about the material of the anti-backlash nut breaking down since it is made of Delrin, a plastic that can be exposed to lubricants and oils.

  • HI..I am having a problem with my machine going off axis and not returning to zero

    Hi, can you elaborate on what you mean off axis? If the CNC router is milling correctly and then suddenly in a location that you would not expect, then you are exceeding the torque of the stepper motors and stalling. If the cnc router stalls, then the cnc router will continue but the software controlling the cnc router will not have the correct position of the cnc router.

    If this is the case, then you need to either reduce the acceleration, reduce the velocity, or both. Does the problem occur during the milling process or during the jogging (rapids)?
