Question #: 621

Question: DON'T WANT TO USE MY OWN MOTORS FOR THE REDLEAF CNC COMPUTER SYSTEM.

Current Solution

That shouldn't be a problem. I will need the current rating for the motors. We can subtract the price of the motors. and you can add you own. If you want us to solder the cable to the round connectors and them motor, you would need to send the motors to us.

Let me know and I can send a paypal invoice for the redLeaf without motors.

  • ALL OF A SUDDEN THE REDLEAF COMPUTER WONT TURN ON...THE CNC PART WORKS FINE, BUT MAIN ???

    For our redLeaf CNC computer system, if the computer system section is none response check if you have power coming in from your wall outlet. If a spare PSU (power supply) is available, try replacing and running with the replaced PSU.


    Additional Information:
    Other considerations will included, RAM module (memory stick), and motherboard. Please verify you have power going to your motherboard first, by noticing if any LED's are turn on. If not Check PSU first.

    Additional Information:
    Yes there is power to the unit. There is a small green light lit on the motherboard and another green light lit near the usb ports. Usually when I press the yellow reset button, the computer starts, but now nothing happens...

  • CAN I USE AN APPLE COMPUTER TO RUN THE CNC?

    There are several CAD/CAM programs out there for MacOS. Here is a list of a few: http://www.macuser.de/forum/f53/3d-2d-cad-395058/#post4499316
    I've also read good things about punchCAD: http://www.punchcad.com/
    Of course, there is always SketchUp if you are in a pinch. There are a few CAM plugins for SketchUp as well, but I've never used them, so I can't vouch for them.

    CAD/CAM will get you as far as designing your parts and producing the g-code, but if you also want to run the CNC machine with your Mac, you will need a piece of software similar to Mach3 or EMC to run the g-code. I haven't been able to find anything like these programs that runs on Mac, so you may have to run Mach3 or EMC in Windows using Boot Camp or a virtual machine such as VMware or Parallels.

    Personally, I would use the Mac to do all the CAD/CAM, then use a cheap PC to run the CNC machine.

  • Can I purchase a computer off Amazon (I have a machine I want to use) and still use the USB interface to drive it with LinuxCNC?

    You will need to build the table unit for your machine. There are instructions on how to do this at the bottom of the product page here, https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4
    There is no estimate on how much this will cost though, since there are too many variables involved to do this.

    - PC with parallel port and USB port
    - 20awg stranded wires for the motors - http://www.buildyourcnc.com/electronicscombo.aspx
    - 18awg stranded wires for power supply to drivers
    - 24awg stranded wires for breakout board to drivers
    (location and spacing of components varies from one person to another, so we do not provide cables/wires)
    - General purpose extension cord (cut the female end off) to provide power to power supply
    - USB cable to power breakout board
    - Parallel cable to communicate to breakout board
    - Router
    - (optional - instead of router) Spindle with power inverter http://www.buildyourcnc.com/SpindlesAndAccessories.aspx
    - (if purchasing spindle with inverter) General purpose extension cord (240v) (cut the female end off) to provide power to power inverter
    - End Mill(s) http://www.buildyourcnc.com/ProductsEndMills.aspx
    - CAD, and/or CAD-CAM software (to produce geometry, machine operations, and g-code) http://www.buildyourcnc.com/CNCsoftware.aspx
    - CNC control software (to read g-code and control machine) http://www.buildyourcnc.com/CNCsoftware.aspx

    This answer is applicable to most of our machines with the exception of the greenLean and the blueChick since those machines are equipped with a table structure.

  • I DON'T HAVE A PARALLEL PORT ON MY COMPUTER. WHAT DO NEED?

    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.

  • How feasible would a vacuum hold-down system be for a vertical CNC like the greenLean?

    Building a vacuum table, for any CNC machine is possible but doing it right might take a adequate amount of information and extensive planning. Depending on the overall complexity you want to build.
    Example, you want sections, and valves that can be operated to close sections of the table to allow vacuum to a specific spot of you material.
    It is possible and would be a very precise method to hold down your material.


    Additional Information:
    Thanks. It may be something I'd like to try on my greenLean at some point. Dan Spangler wrote a nice article on building a "Universal" CNC vacuum table in the latest issue of Make magazine, volume 41.

  • I would like to use Mach3 instead of the software for my CNC router. Can you fix the electronics for me?

    Yes, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

    Some of the types of CNC electronics we will consider.

    - We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

    - We will repair or retrofit used CNC electronics.

    - Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

    The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.

    Here is an example of CNC electronics that we worked on for a customer:



    This is the type of response that you can expect to receive after the CNC electronics are repaired or retrofitted to work under Mach3, Mach4 or LinuxCNC. You can see the entire work, which also shows the time involved. We also show what we were able to accomplish at the beginning of the video.

  • HOW CAN THE ROUTER BE CONTROLLED OR CONNECTED TO ELECTRONICS COMPUTER?

    The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

    If you are interested in the USB breakout board, you will need to get an independent relay board.

  • WHAT CAUSES ONE OF MY TWO AXIS MOTORS TO STOP WHILE THE MACH3 PROGRAM IS STILL RUNNING

    If one of your stepper motors decides to stop moving and the others are moving during a CNC milling or laser cutting job, then there could be two things that could be causing this.

    - The motor found its limiting torque (usually comes with a not-so-pleasant sound). This is where the control software is trying to move the stepper motor too fast (velocity, or too fast too quickly, acceleration) and the load against the stepper motor (inertia of the machine, or the material against the end mill while milling). Recommended action is to lower the velocity and/or acceleration, and/or lower the feedrate when cutting.

    - There is a wiring issue with the wiring from the driver to the motor. This could be a loose wire, or a chafed wire (or two shorting together). It can also be a loose digital wire from the controller board to the driver. Sometimes wire ties can be the culprit. Recommended action would be to thoroughly inspect the wiring.

    It's probably not the limit switches since that would cause a stop to the entire motion of the cnc router or laser machine.

    Sometimes Mach3 will show a status when something goes wrong, but in cases where the motor is stopping due to its torque limit, then that would not be shown in the status. It's always good to check it anyway.

    Additional Information:
    I need to clarify my situation a little better after going to my shop and trying to run another program on Mach 3. About 15 minutes into the milling process all the motors (2-X axis, Y axis and Z axis)stop but the program continues to run. I stop the program and after a couple of minutes when I try to restart the program all the motors start working again. Then after another 15 minutes or so, all the motors stop again. I checked and rechecked my wiring. This has never happened to me before when running the same programs with the same setups and motor speeds. All of a sudden when I reloaded a program I successfully used before it does this. Do you have any recommendations?

    Additional Information:
    Yeah, it sounds like a more complex issue. Have you tried running in the air without using the spindle. This may be a power related issue.

    Additional Information:
    That's exactly what I did. I ran the program without the router motor on just to see if the motors would get through the whole program but they stopped working after about fifteen minutes and then I was able to start them again after about 3 or 4 minutes. I never had this problem before so you can imagine my frustration especially after ruining a couple of projects on expensive material.

    Additional Information:
    Sure. I can completely understand. Try this: disconnect all but one of the driver from power and digital connection and do the air run. Repeat this for each driver and note your findings. This will rule out the drivers causing a power failure.

    Also, is your stepper motors and drivers on a separate power circuit from the computer?

    Additional Information:
    I will try disconnecting each driver and digital connection, which will be a real pain because it will be hard to access.

    All the stepper motors, drivers and computer are plugged into the same power strip.

    Additional Information:
    Ok, so there is no power failure going on, but I believe it is necessary to test each stepper motor and driver pair individually. Hopefully that will lead to a conclusion.

    Additional Information:
    It will take a little time but I will do it and report back on my findings.

    Additional Information:
    Curious, what machine is exhibiting this problem?

    Additional Information:
    I purchased a BYCNC kit back in 2009 with an approximate cutting area of 2' X 4'. I later changed out the Z-Axis Motor and controller for a larger one and have two X-axis motors and controllers. In 2010 I rebuilt the machine out of birch plywood instead of the particle board that the kit supplied. I sent Patrick pictures to him. The machine never gave me a problem till now.

    Additional Information:
    Thanks for the update. This is Patrick by the way. I answer pretty much all of the Customer Service questions. That machine has given quite a good history.

    Additional Information:
    I love the machine and made a number of samples of my work for my e-commerce site, but I can't start selling product until I know this problem is solved because I will not be able to fulfill orders. I finally got all the electronics out of its enclosed protected area near the machine so that I test each controller as you recommended. I hope the problem can be rectified. Will let you know.

    Additional Information:
    Thanks.

    Additional Information:
    I tested each stepper motor and driver pair individually and they worked so what might be the next step?

    Additional Information:
    Did each stepper motor driver pair work for the full +15 minutes?

    Additional Information:
    Yes, I had them in operation for over 30 minutes.

    Additional Information:
    Ok, well it’s good that the motors and driver are ok. We are now down to the power supply and the breakout board as possible causes for the stop. I have a feeling it may be the power supply where with all three drivers drawing current and the power supply maybe getting too hot. Is the fan in the power supply working? You can also test to see if there is 36 volts on the power supply voltage output (V+ and V-).

    Regarding the breakout board, if you have an oscilloscope, you can test if the driver pulses are outputting, but I would consider this as a last resort after you determine if there is a problem with the power supply.

    Additional Information:
    I tested the power supply with a voltmeter and each output was registering 39-40 volts. I think the problem may be the g-code. I am using V-Carve pro to do design and output to Mach 3 Mill g-code. When I studied the g-code lines I noticed that further into the program the z-axis g-code stopped zeroing out to move to the next part of the carving. In other words both the x and y keep moving and the z just stopped working because there was g-code missing. I think something is missing when the design was converted to g-code. I noticed that when I ran a simpler project it worked without problems so I need to investigate this further.

    Additional Information:
    New Update, Its not the g-code. I started to run the long program and everything was working fine until about 45 minutes into it, all the motors stopped working (but the program was still running) and there was a high pitched hum. When I put my hands on the motors they were all trying to move but it seemed they were all stalled. I turned the power off, gave it a minute and when I turned it back on I was able to move the motors again. Could this be a power supply problem?

    Additional Information:
    It does sound more and more like a power supply problem. Did you test the power supply after the motors stopped?

    Additional Information:
    No, I did not. What should I be looking for.

    Additional Information:
    It’s good that you know the voltage during normal operation, so you have a base understood. If the power supply is the problem, the voltage will be reduced or non existent when measured after the problem.

    Additional Information:
    Also, check to see if the fan is running on the power supply when the motors stop. That may (not absolutely) be an indication.

    Additional Information:
    I'll run another test, check the voltage and fan when the problem occurs and let you know. Thanks for hanging in there with me as we try to resolve the problem.

    Additional Information:
    It’s my pleasure. This service is rarely used and is faster then email. Odd nobody uses it. Any recommendations you can give would be great. No problem using this FAQ to pose ideas as this resolution will be cleaned up later.

    Additional Information:
    It might be that people do not realize you can communicate through the sight like this because they are so used to e-mail and texting. You may want to explain this feature in the customer service section.

    I ran the program this morning and it did not take long before the motors stopped. While operating the voltages for all three motors was 46 volts, when the motors stalled (and again there was a high pitch hum) the voltage went up to 60 volts and the fan on the power supply was operating.

    Additional Information:
    So, the driver work individually, but not all together. There is a high pitch sound when the motors fail. You have noted 60 volts from the power supply and the supply fan remains on. This is a difficult issue to resolve, but it seems to me that your power supply may be bad. The 60v measurement tells me that the current dropped and ohms law tells us that is current drops, volts will rise if the resistance stays the same.

    Additional Information:
    As one last test I am going to test each driver again and let them go through the entire program because it seems that the failure can occur at the beginning or towards the end of the program. When I originally tested ach driver I let them run for about a half an hour and the program takes over an hour to run completely. I just want to make sure that it is not the drivers. I will report back when I finished but as you noted it may be the power supply but I want to make sure.

    Additional Information:
    That’s a great idea.

    Additional Information:
    I just ran the x-axis through the whole program and there was no problem especially since I have two NEMA 23 motors moving that axis. Before I check the Y and Z could having a NEMA 34 on the Z axis with appropriate controller be a problem. I used the larger motor on the z axis because the router I am using is a large 1 1/2 hp. I've run this program in the past with this set-up and have not had a problem.

    Additional Information:
    Having a, say 3.0 amp driver, driving a stepper motor that typically requires a 6 amp driver would not seem to be an issue since the driver is limiting the current draw, but the driver may not be able to handle larger coil and back EMF with the protection on the 3.0 amp driver. With that said, I don’t believe that is the issue in this case.

    Additional Information:
    I don't either because I was able to run this and other complicated programs with this set-up in the past. I will let you know on the y and z axis.

    Additional Information:
    Thanks

    Additional Information:
    I ran the Y axis and z axis separately through the entire program and there was no stopping or problem. I guess the culprit is the power supply and I'll order a new one and hope that resolves the problem.

    Additional Information:
    Yes, that is the most probable cause. Please keep me informed. Thanks!

    Additional Information:
    Received and installed the new power supply. I ran the program with the router on and it worked flawlessly. The program runs for an hour and a half and I did not have a single problem. I guess it was the power supply but I was glad to go through all the diagnostics we discussed before replacing it. I hope this power supply lasts a lot longer than the last one. Thanks much for hanging in there with me and coming up with the solution.

    Additional Information:
    It’s my absolute pleasure and I am so happy to hear that the power supply replacement solved the problem.

  • I have not used my CNC router (Mach3, USB interface board) for several months. When I tried to use it, all 3 stepper motors moved extremely slowly. Where should I start troubleshooting?

    If your motors turn very slowly using your Mach3 USB board, then either the pulse from the board is being output at a slow rate or the motor drivers are set to a higher than expected microstepping:

    The Mach3 USB board outputs the pulse rather than the computer, but Mach3 controls this pulse frequency within the motor tuning section. First, determine if the travel distance is correct with the computer and the physical travel of the machine.

    If the travel is different, then your stepper motor driver's microstepping is incorrect, or the steps per inch/mm in the motor tuning within Mach3 is incorrect.

    If the travel is correct, then simply change the velocity and acceleration parameters to your desired level. If Mach3 will not achieve the velocity you desire, then decrease your stepper motor driver's microstepping setting, readjust the step per inch/mm in mach3 and readjust the acceleration and velocity to your desired levels.
