Question #: 14523

Question: i zero out the z axis on a file ad about have way through the bit is lower then it started. about 1/8 off

Current Solution

Sounds like it is stalling as the z is trying to move up. I would first try putting 3-in-1 oil on the screw and run the z up and down a lot as fast as possible so you can confirm the z is capable again. It could also be the shaft or the lead screw slipping in the coupling. Finally, check the wiring where there may be zip ties or other places where the wires are fastened and look for chafing. This can cause intermittent shorts in the wires.

  • can I control the speed of a 2.2 spindle through your 5 axis breakout board with relay?

    Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. It requires making some changes to the settings in Mach3 and in your inverter. It also requires an additional part, which is called a USB to Serial Converter, found on our site here:

    https://www.buildyourcnc.com/item/Interfaces-newbiehack-Interfaces-TTL232R-USB-UART-Serial

    I have some additional instructions, that I will send upon request, by email. I will also be adding a complete tutorial and video, to the website, on how to do this soon.

  • I couldn't find any information about how to mount the "z-axis lead screw in the book" (Build Your Own CNC)

    The details will differ depending on the type of lead screw you use.

    For allthread lead screws, you will need the 1/2" square nut, 1/2" allthread lead screw, two 1/4" screws and nuts to hold the square nut in place, two 1/2" ID bearings, two standard 1/2" nuts, and one coupling hub.

    Attach the square nut to the nut support using the two 1/4" screw and nuts. The bearings will need to be inserted into the seats of the lower and upper part of the z-axis. Insert the lead screw through the top bearing. Use one of the standard 1/2" nuts and start threading it on the allthread screw just below the bearing. Lower the lead screw to the square nut and start to screw the lead screw into the square nut. Continue until the screw is near the lower bearing. Add another standard 1/2" nut to the screw and keep turning the screw until the screw just passes the lower bearing. Add the coupling hub to the top of the screw just above the upper bearing. Turn the lower and upper standard 1/2" nuts until they are snug against the bearing. If the standard 1/2" nuts become loosened, consider adding another nut to each end against the existing nut to keep them in place.

    For 1/2" acme 5 start lead screws, you will need to use an antibacklash nut in place of the square nut. This nut attaches with a flange using two #8 screws and nuts. The standard 1/2" nuts are replaced by clamping collars.

  • I am thinking about buying one of your kits. Do you offer a way to interchange bits without using wrenches. also do you have an option to add an additional smaller spindle for drilling parts?

    Currently we have no option for auto-tool change as this feature is mostly limited to higher-priced heavier duty spindles. We are aware of some new technology being developed to bring auto-tool to lighter duty spindles. We will be following the progress of this development closely in order to bring this option to our website whenever it becomes available.

  • Is the parallel breakout board in the kits capable of being wired to turn on/off the spindle through mach3/estop or will it require additional hardware?

    The parallel breakout board is able to control the spindle using its on-board relay circuit. Full instructions on how to wire the spindle to the breakout board and configure mach3 can be found here:

  • BUT DIDN'T SEE ANYTHING ABOUT COOLING THE LASER OFF - IS YOUR SETUP LIKE MOST OTHERS NEED BUCKET OF DISTILLED WATER TO PUMP THROUGH MACHINE?

    Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

    1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

    2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

    3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.

  • I have a BlueChick that came with the 5-Axis Bread-Out Board V5 (parallel port), it has 3xCW230, how to configure it on LinuxCNC?

    Strictly to the point. Assuming:
    -You have a working linuxcnc install with a compatible parallel port
    -You have wired Bread-Out Board V5 to the motor drivers so you know which pins are for which signals(watch video tutorials for that on this site)
    -You have wired motors to motor drivers (watch video tutorials for that on this site)

    a)We need to know the base parallel port addres, for that you need to input on a linux terminal the command:

    #lspci -v

    You can scroll up and down the result with page up and page down. Look for a "Parallel Port..." line, the value you are looking for is the "I/O Ports at.." Write them down

    To get the Base Period Maximun Jitter, go to
    applications - cnc - Latency Test

    Now you should let that window running for a while, so it calculates an accurate jitter, go watch the tutorial videos for the connections between the Bread-Out Board and the motor controllers.

    After its been running for half an hour or so with the machine in use, write down the calculated jitter values, mine was Servo Thread - 39000

    Now close the Latency test dialog

    b)Go to applications - cnc - stepconfwizard
    "START" - Create a new config
    Check - Create Desktop Shortcut to config files
    Check - Create Desktop Shortcut to start linuxcnc with this config
    FORWARD

    c)"BASE INFORMATION"
    Fill in a Machine Name that suits you
    Bluechick is XYZ on inches
    Fill in the Base Period Maximun Jitter with the value obtained in "a)"

    FORWARD

    d)If you watched the tutorials on a) and b) you know the pin numbers for your signals.
    Parport Base Address you need to put the value obtained in a), mine was cf00
    Output pinout presets I used Sherline

    FORWARD
    FORWARD

    e)Axis X (chain and sprocket axis)
    Data for bluechick from build yourcnc
    Motor Steps per revolution 200
    Microstepping 64 (that if you followed tutorials, change if you have different)
    Pulley teeth 1 ; 1
    Leadscrew Pitch 0.444444 (that value comes from 1rev / (.25 in * 9 teeth))
    Maximun Velocity 10
    Maximun Acceleration 0.5
    Home location 0.0
    Table travel 0.0 to 34.0 (maybe you want to change this later)

    Now, you can do "Test this axis" and jog it (move it!) Try to position everything in the middle (you will be doing it axis by axis) and select
    "+ 0.5 in" Hit run, I used a pencil held at the gantry and paper to draw a line, then confirmed that the measurement was 0.5 in. Also tried with "+/- 0.5 in" and confirmed 1" measurement

    FORWARD when happy with your Axis X

    Repeat for Axix Y but the table travel is 0.0 to 12.0

    f)AXIS Z
    With data from buildyourcnc.com
    Motor Steps per rev 200
    Driver Microstepping 16 (as recommended for lead screw)
    Pulley teeth 1 ; 1
    Leadscrew Pitch 2
    Max Vel 2.5
    Max Accel 0.5

    Table travel 0.0 to 3.5

    Test, and FORWARD when happy

    g)After configured you can go to
    Applications - cnc - LinuxCNC, and there you go...

  • For the thread rod on the x asis, You have a device for the thread rod to ride through ?

    For our machines the threaded rod will be included with only our whiteAnt, an it is only sustained with to nuts on each side where it goes through the structure. Nothing besides the structure is it riding through.
    For the scratch build kit, if a threaded rod is being used please refer to using a anti-backlash nut similar what we carry (https://www.buildyourcnc.com/item/mechanical-leadscrews-antibacklash-nut-!375-2-starts-10-tpi).

  • My spindle is creating an unreasonable amount of pressure headloss! Is there a way to clean our the water channel inside the router to get the water to flow through it better?

    To rush/clean the water from the spindle, you will need a air compressor or air tank that you will use with a blow gun, which you will rush air through one end cleaning the water from within the spindle.

  • I WOULD LIKE TO INQUIRE ABOUT THE PHYSICS PRINCIPLES REGARDING USE OF MOBILE PHONES AND DEVELOPMENT BRAIN TUMORS. I'VE BEEN THROUGH MANY SITES BUT THEY CAN NEVER GIVE AN EXACT ANSWER. REALLY SOMEONE TUMORS OR DOES IT HAVE DO WITH INTENSITY RADIATION DISTANCE BETWEEN PHONE INDIVIDUAL?

    It is not clear that mobile phones do produce brain tumors, or any serious health effects for that matter. A number of epidemiology studies have been almost completely negative on the issue.

    See the article I wrote with John Moulder in IEEE Spectrum magazine and also Moulder's FAQ on mobile phones and health.

    There has been a lot of discussion over the years about the possible mechanisms by which microwave energy such as emitted by cell phones might produce biological effects. The one unequivocal mechanism is the heating of tissue, but mobile phones operate at power levels that are too low to cause noticeable heating in the user. Scientists have speculated about other mechanisms, but these theories remain unproven and many of them have been challenged on biophysical grounds.

    Whatever may be the risks or nonrisks of mobile phone radiation, a hands-free kit is an effective way for the user to reduce his or her exposure to radiofrequency energy while using a mobile phone.

  • I built a 2' x 4' cnc about 2 years ago and bought all the plans and part through this website. My average 2D design takes approximately 35-40 minutes to complete. Is there a way to make my cnc faster?

    Yes, if you are using 1/2" standard allthread lead screw coupled to your stepping motors, you can increase the speed by changing the lead screw to 10 TPI 5 Start Lead Screws with antibacklash nuts. This will allow you to have up to 200-300 IPM (inches per minute) travel and cutting speeds.

    The reason why the feedrate and jogging speed is faster is because the lead screw will travel a farther distance for each turn of the motor. A standard allthread will only travel one inch after 13 turns of the motor. The above (link below) 5 start 1/2" lead screws will travel one inch with only 2 turns of the motor! That is a drastic difference and you will get more torque from your motor since most of the torque is present at low speeds.

  • are you out of your freaking minds with these shipping rates. About to go through with order but you lost me! Good luck!

    Thank you for your feedback. Generally we are considered to be quite sane as a collective, although this can change from time to time.

    We have a disclaimer on shipping rates, especially if you are ordering from outside of the United States, rates are generally shown only for air-shipments from USPS, UPS, and FedEX, which can be quite expensive. We do work with several freight and shipping companies that allow us to calculate options for lowering shipping costs. These companies do not generally have APIs that we can integrate into the website, so we need time to process quotes.

    If the shipping quote you received from the website seems unreasonable, there is a good chance we can quote you a better rate. All you need to do is inquire with sales@buildyourcnc.com and we will make sure we get you the best possible rate.

  • My CNC machine has suddenly started going in only one direction in the Y axis. It was working fine for several days and then started going in a single direction when I would do a manual job.

    We have ran across this issue on occasion, and usually results is there is something along your wiring that is causing a fault or is not getting good contact.
    We would recommend going through the wiring thoroughly and checking continuity with the y-axis wires, going from your USB or Parallel BoB to the driver.

  • The spindle has started on my Machine while the machine was sitting idol, I'm not sure if the relay has failed on the breakout board. Is there a way to test this?

    First, you should check the configuration in your CNC control software and determine if the spindle control pin is correctly set. That pin will engage the relay.

    The P and O position of the relay is set as Normally Open where the relay is open (open circuit, or no connection) at idle and when engaged will be closed (closed circuit, or connected). If you suspect that the relay is damaged, the recommended action would be to disconnect the spindle from the relay and operate the spindle/VFD manually using the Run and Stop buttons on the face of the VFD (until the breakout board can be replaced).

  • Is it possible to increase the Z axis on the Blacktoe 2x4? My ideal would be to have 8" of travel.

    Increasing the size on your Z-axis is possible by making the over z axis longer (rails, wood structure). Remember the location of your router/spindle and over all integrity of the z-axis structure.
    Now another way of getting a longer reach is making a adjustable height table, so that you can raise or lower the material section(2' x 4') to add taller material or get a deeper cut.
