  • Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?

    Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

    Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

    A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.

  • I am building a cnc router with twin ball screws on the long axis and I will have a rotary axis as well. I need a 5 axis breaker board using only 4 axis total. Can you help me?

    Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.

  • I am building a wet plasma table for my shop that is 8'x 16'. I will need hardware and software. Please heko me wuth the list, My phone is 9124273734. I would like to talk with someone if possible. Thanks, Rus

    If you purchase the greenLean, you will get everything you need except a router, computer to operate the machine, and software to control the machine. You state that you have a computer. You can use this computer, but you will need to determine if it has a parallel port, or if you are going to need the USB controller option. As for the software, there are too many different options for you to choose from. We would not be able to tell you which to get, and how much it will cost you. This is a matter of preference. I can tell you, however, that you will need 3 types of software to complete a CNC project. You will need CAD software to design your design, CAM software to add tool paths and convert the design to g-code, and then control software to take the g-code and operate the machine.

  • I recently purchased the linksprite cnc engraving router and was wondering if your 3 axis small kit would be ok? the engraver came with nema 17 motors and a arduino board but but not liking the grbl control. could you point me in the right direction .Thanks.

    Sure, our blueChick and blackToe CNC Routers are considered relatively small machines at 1'x3' and 2'x4' respectively. They both use NEMA 23/24 motors. We recommend connecting the machines to either Mach3 or LinuxCNC and come with the necessary interface for either control software. You will need a computer for the control software and if you desire LinuxCNC, you will need a parallel port. Mach3 will accept either parallel port, or USB interface.

  • I was wondering if it is at possible to get a autocadd drawing of the pieces that need to be built for your cnc hardware kit

    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.

  • I AM PUTTING TOGETHER THE BLACKFOOT AND USING A PORTER CABLE ROUTER. CONFUSED ON HOW TO RELAY ROUTETR WITH USB BOARD. IS THERE ANOTHER SWITCH THAT GOES BETWEEN BOARD ROUTER SO PLANET CNC CAN TURN PERHAPS VACUUM OFF?

    We are currently working on a relay board that will connect to USB breakout board, and the router/spindle for both the on/off function. Unfortunately we still do not have it completed or ready to be placed on our website, but it is in the final stages of testing. Please check back regularly for updated stock!

    Here is a link to a tutorial for a DIY relay circuit:



    There is no vacuum control on the Planet-CNC program, however you could use the same concept of the router/spindle on/off using the relay circuit. Although you will have to use either the flood or mist function for the vacuum.

  • when cutting patterns with my cnc router there is significant chatter in the cut-I've replaced the router-what else should I try?

    Do you use the same bit?? If so, check if it is not dull or worn. Maybe it is time for a new bit. Additionally, I would check if the z axis mounts are tightened correctly and the router has no wiggle room. If that doesn't help, check all of the play that may be in the structure and where the bearings run along the rails and tighten all loose connections that may be present.

    Additional Information:
    So confused....is backlash and chatter the same thing or are they completely unrelated?

    Additional Information:
    Chatter and backlash are different. Backlash is a condition where there is play in the mechanical parts (i.e. a nut not tight against the treads, or two gears not meshing together tightly). Chatter is a phenomenon caused by many possible conditions including vibration, resonance, springiness and flexibility in the system and certain types of end kill and machine movement scenarios.

    Additional Information:
    Meant to say end “mill” at the end there.

  • How thick can the Greenbull cut and what kind of material? Wood, plastic, steel? I was also wondering if there is one anywhere in Nevada, Idaho or Utah that I could possibly see in action. Thanks

    The greenBull CNC machine kit can cut as thick as a material as you desire depending on the reach of the end mill that you provide the machine, if it is a straight vertical. The reason for this is that each pass is incremental (multiple passes at a certain depth per pass). For instance, if you need to cut a 2 inch thick piece of wood, you can make, say 3/4" passes until the target depth of 2 inches is met.

    The depth per pass, feedrate and RPM will be determined by the material: wood, plastic, metal and will also be determined by the end mill that is used for that material. Selecting the appropriate end mill is very important. Feedrate and RPM is important to make sure the end mill is as cool as it can be during the cutting process.

  • I am looking at buying the blacktooth-laser-cutter-engraver-40w. Can you give me some idea of the types and thickness of material this machine will cut and/or ingrave?

    Considering that "materials being lased by may emit gasses that are harmful to humans (corrode human tissue and cause damage to respiratory organs). Always read the MSDS (Material Safety Data Sheet) for the material to be lased. You can find these MSDS from manufacturer websites for the material you are considering for use in the laser system."
    We successfully have worked on Thin sheets of Brasswood, glass, foam, plexi-glass. The thickest materials you will be able to successfully cut is 1/4".

  • I PURCHASED YOUR BOOK TO BUILD A CNC ROUTER, THE PLAN DRAWINGS ARE INDECIPHERABLE AND TEXT WITH THEM IS ILLEGIBLE. THERE NOTE REFER MDF PARTS LAYOUT 1 PDF, 2 PDF PLANS & CUT LIST DOWNLOADABLE FROM THIS SITE. WHERE THEY CAN'T FIND THEM?

    Looks like you are trying to screw me out of $30 plus tax as there will be no pdf files forthcoming unless I shell out another $255. Unless you provide the pdf files I will be forced to seek return of funds and will be notifying VISA, GOOGLE PLAY and the BBB doing so until I get satisfaction. If you are not going to honor your book title by providing complete usable information you should remove your book from the market place, or offer it for free. At this point I don't know how you justify screwing your customers like this, but this one ain't going to take it laying down.

  • I have nearly completed the CNC machine from the book, but I am using it with a USB breakout board, and have no idea how to wire the 6 limit switches to the board. I'm having difficulty following the diagram on the USB breakout board screen. Can someone please help me?

    Sure, the USB interface has a place for 4 axes of limit switches.

    Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

    A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

    Let me know if this information was helpful (or not) by adding information to this question. Thanks.

    User response:
    Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
    Thank you.

    buildyourcnc response:
    On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

    Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

    In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

    There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.
