Question #: 14898

Question: [4th Axis with Tail Stock] is therer a harmonic or planitary gearbox in nthe headstock, or is it just driven by the pully?

Current Solution

No, the motor shaft is directly coupled to the chuck via timing belts and drive pulleys. The mechanical advantage in this system is by using a small drive pulley on the motor shaft to the larger drive pulley on the shaft of the chuck.

  • DOES THE RADIATION ONLY EXIST WHEN I'M ACTUALLY MAKING A CALL, OR JUST ANY TIME PHONE ON?

    Whenever they are turned on, cell phones communicate at infrequent intervals with a nearby base station even when they are not being used for a call. This is necessary to tell the system where the user is in case a call should come in. Thus, even while they are inactive, the phones are a source of (very low) radiofrequency energy exposure to the user. Hands-free kits reduce exposure to a user by removing the phone from the vicinity of the head. There is no identifiable health benefit in using the kits, but there is no detriment either, and using them may increase a user's peace of mind. Contrary to a widely publicized report by a British magazine last year, the kits are effective in reducing exposure. (This is not necessarily true of other devices that can be bought to be used with phones.) In your case, the cell phone and hands-free kit are clearly an important link to the outside world and I would not hesitate in using them. There may be comfort issues with having the earpiece in place for a long time, but radiofrequency radiation exposure should not be a concern at all. The hands-free kits will reduce exposure below that which you would receive if the phone were kept close to your head. Kenneth R. Foster Professor, Department of Bioengineering

  • DO NEED TO GET THE BIG PLANING BIT OR SURFACING AND GO OVER SPOIL BOARD MAKE SURE THAT IT IS PERFECTLY LEVEL IN RELATION ROUTER?

    Yes, that is highly recommended for all the reasons you can imagine. Say you were doing engraving, not surfacing the spoilboard will either exhibit some areas that have no engraving at all, or areas that have engraving that is too deep. If you are cutting completely through the material, then one end may be cut all the way through but the other end will not have a complete cut, or produce onion skinning on the bottom of the workpiece.

  • IS IT OK TO LEAVE THE VACUUM PRESSURE CONTROLLER PLUGGED IN ALL TIME WHEN PUMP SWITCHED OFF?

    I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

  • Will it be possible to only buy the CNC plans, I live in South Africa and shipping is very expensive...

    The files and hardware option for our machines has been removed from the site due to the following reasons:
    Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
    The abuse of these files over the internet.
    Ultimately may reduce the sales of machines keeping us in business.
    Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.

  • THE CNC MACHINE IS UNSAFE WITH EXPOSED SPROCKETS THAT CAN DAMAGE FINGERS AND HAVE CLOTHING CAUGHT IN IT.

    These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

    With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

  • MOTOR GOING TWO DIRECTION WHEN JUST PUSH UP. IT WILL GO DOWN AND THEN GOES AGAIN UP WITH THE SAME BUTTON.

    Try slowing your feedrate down and increasing spindle RPMs. End-mills will leave a poor finish if you go too fast. Make sure your cutting depth isn't too much. Maybe the endmill or cutter is blunt? Could it be the feed direction of the cutter? Some materials need to be fed in a certain direction.

  • Can we use a more powerful laser tube in the blackTooth? Say, 100w from ColeTech? Are they just physically too large/long?

    If the laser tube is the same dimensions then yes, that tube can be implemented and take into account the required laser power supply and safety protocols on that high powered laser tube.

    Our blackTooth is a fixed machine and is only made for the 40 watt laser tube that we sell.

  • I BOUGHT YOUR BOOK AND WAS HOPEING IT HAD PLANS OR DIMENTIONS ON HOW TO BUILD A CNC HOLD 4X8 SHEET OF PLY. WILL THE IN SCALE UP?

    BYCNC Response:
    The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

    User Response:
    I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

    BYCNC Response:
    It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

  • 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.

  • [410] what I need to buy to make this work on my GreenBull machine and the redfly?

    Since this 4th axis already comes with a stepper motor, you will need a driver and some cable to connect to the driver from where the 4th axis will be placed. If you have extra space in the redFly electronics enclosure, you can fasten the driver there. You will also need some wire to connect the driver to the breakout baord.

  • I JUST RECEIVED A REPLACEMENT SPINDLE (2.2KW 220V). HOWEVER, WHEN ATTEMPTED IT USE THE NEW SPINDLE, WOULD ONLY REACH 1500 RPM. IS THERE SOMETHING NEED TO CHANGE ON CONTROLLER?

    VFD settings........
    1) To program the VFD, wire it up, plug it in. It takes several seconds to come to life.

    2) Push the PRGM button to enter programing mode.

    3 )Push the SET button. The display will read PD000.

    4) If you push the SET button again, it will display the present setting of PD000.

    5 )By pushing the up or down arrows, you can change the setting to whatever it needs to be. (This is just an example. PD000 needs no changes)

    6)Push the SET button again to lock in the setting of PD000 and advance to the next number, in this case, PD001.

    7) Push the SET button and it will display the present setting of PD001. Again, use the up and down arrows as necessary to set PD001, then push SET again to lock it in.

    Note: You can also scroll through the PD numbers with the up and down arrows.

    8) make all settings this way.

    9) by pushing the SET button you can scroll through the settings. First push of SET moves to the next number, second push displays it's setting, third push moves to the next PD number.

    Note- If you take too long, it will leave the programing mode on it's own. If it does, just push PRGM again to return to programing mode. Then press SET and continue what you were doing.

    10) Start with PD013. Set it to 1, which returns the settings to the factory settings.

    11) Then set PD005 to 400, PD004 to 400, and PD003 to 400 IN THAT ORDER.

    12) Then set the following: PD041=8, PD144=3000

    13) Set PD209=50

    That's it for the programing. You should get 24000RPM when you push RUN.
