Question #: 14670

Question: 'Z' axis, I push the down button the unit goes up, when I push the up button it also goes up. It's been doing this off and on for awhile

Current Solution

The direction wire for that axis is not securely connected. Remove that wire from both terminal ends and reconnect more securely. You may need to completely change the wire just in case there is damage to the wire between the ends.

  • 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.

  • My Z axis motor changes direction in the middle of an operation. It starts out correctly, than in the middle of an operation the Z axis goes in a negative operation instead of the positive direction. When I reset after this having the Z axis go down it goes up, and then asked it to go up it also goes up?

    That is a simple loose connection. How the direction connection works. There is a high state (5v), and a low state (0V or ground). If the down operation is the high state and the connection is not good, the connection could go to a low state and then go in the opposite direction.

    Check the connection and confirm it is secure.

  • Spindle is making a strange sound for a few seconds then shuts off. It is also tripping the breaker on the surge protector. Is this fixable? https://youtu.be/aofbvY3RnIw

    Yeah, that is not right at all. I think you either have an issue with the shaft, or the bearings are bad. Probably the latter. How old is the spindle?

    Additional Information:
    I bought this off craigslist so it is at least 3-4 years old. I've been hearing an odd noise for the last week or two so I'm thinking it was starting to fail.

    Additional Information:
    I would say that it has lived its life. In CNC routers, routers will last far shorter time. Spindles are relatively inexpensive, so I would just replace it.

  • Hello, I bought your 110v 2.2kw spindle and vfd. When I turn it on it reaches the full 24000 rpm, but will not let me decrease the speed. How Can I fix this?

    Are you using the control panel (front panel with the speed control knob known as he potentiometer)? Or are you attempting to use the computer to control the speed?

    Additional Information:
    I am using the control panel, however there is no knob on mine, just buttons.

  • I have a usb cnc driver board on your 1'x3' cnc and i cant get the z+ limit switch to stop the machine in the provided software. It registers the button but doesn't inhibit movement. inversly the button works when selected as '-' for negative movement.

    All USB boards, are tested and checked before shipment for all axis, and inputs. Here is a link with clear instructions on how to setup Planet-CNC (http://www.planet-cnc.com/faq/machine_setup/).

    Please check continuity and for any crossover disruption when wiring your board, try to wire each as cleanly and with out crossing any live power wires and or motor motion wires.

  • I wpold like to know how to hook up my water pump (12vdc 9 amp) to turn it on and off using Mach 3. I have your Blue Brew break-out board Rev. 2.8 dated 8-12. Explain how the three relay connections work for this application? Thanks.

    Since the pump will use a standard 12v power supply, you will have two wires. One of those wires will be connected from the power supply to the pump. The other wire will be connected to the power supply and the pump, but cut that wire and connect one side of it in the P terminal and the other end in the S or the O terminal depending on if you need the connection as NO (Normally Open) or NC (Normally Closed).

  • I'm using the big 651oz in stepper motor for X and Y and the smaller 325 for the z and X and Y keep tripping when I try to tune the motors on Mach3 but Z seems to work. I have to turn power on and off to reset....is this a wiring issue?

    This is most likely a wiring issue. I would disconnect all of the power to the drivers and reconnect one at a time to isolate the problem.

    Additional Information:
    that was not helpful. I already did that way before submitting this question. there are not that many wires here and I have already rewired this a few times. I actually think its a software or interface board issue because it does work sometimes but then trips (possibly a amperage / voltage issue) I am using the interface board that has a parallel port and usb for 5V. are there different settings that I need to setup?

  • I PLANTED SEVERAL CONCORD GRAPE VINES DURING THE PAST FEW YEARS. GOT A COUPLE OF VERY TINY BUDS THIS YEAR, BUT THEY DRIED UP AND DIED. WHAT AM DOING WRONG?

    Everyone always assumes they are doing something wrong when a plant fails to perform to their expectations. Grapes need pollinator activity to set viable fruit, but there is a shortage of bee activity throughout the country. When the flower cannot be pollinated by bees, the resulting fruit usually atrophies. It is not your fault, just a shortcoming in nature's network.

  • I'm trying to get the planet-cnc mist, coolant and spindle output to work. It's showing no voltage when I test

    On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.

    Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.

    Additional Information:
    I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?

    Additional Information:
    There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.

  • I have a home built CNC running Mach 3. I have power to all the motors and the breakout board but no movement when running g-code. I cannot even manually move the motors with the arrow keys or page up and down. It also has an integrated 120v receptacle showing an open ground. I don't know if all this is related.

    The fact that you cannot move the motors with the keyboard serves as a clue to a couple possibilities.

    - The software may not be communicating with parallel port. (One possibility may be that your step pins are not low active, or vice versa depending on your drivers).
    - You may not be in the correct tab of Mach3. Make sure you are in the Program Run tab.
    - The jog on/off button on the program run screen may not be lit (invoked).

    This address below shows the complete troubleshooting for this type of situation. It will show how to test each pin at the parallel port at the back of the computer and everything else associated with correctly wiring the electronics.

  • I have a planetcnc USB controller to run my project and when I start the 240v router the USB connection shuts down.

    The USB controller will only work with the Planet-CNC software. This software is well made and will provide great functionality. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly.

    There are two main alternatives if you want to use the mach3 software:
    First, get a parallel port card and add it to your computer and get a parallel breakout board. If you have a laptop/notebook computer, this will not be possible.
    Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3.

    Additional Information:
    The planet cnc controller can be prone to electrical interference and has been known to cause such problems. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Alternatively you may need to sheild your limit switch, estop and or motor cabling. My pick is that a quality USB cable will fix it though, worked for me.

  • The tube is illuminated but I don't get clear firing to the piece. This is a rastering work and I get faint results and then it will be fine, then nothing. Tube changes from pink to solid line purple even when vectoring or manually holding the fire button.

    If your laser machine needs to reflect off of three mirrors before it finally passes the focal lens, then I would recommend realigning the laser.

    You might also want to see if the nozzle is hot. If so, then the laser energy is hitting some of the nozzle body and not all of the laser energy is exiting the small aperture of the nozzle. To determine if this is the cause, remove the nozzle and try the operation again to see if you have better results. If the results are better with the nozzle off, then realign the mirrors. If you are still having difficulty getting the laser energy to exit the nozzle, increase the diameter of the nozzle aperture.

    If you are still having poor results, take a look at the focal lens and the mirrors for any debris. An unclean lens and mirrors are a common cause of poor lasing performance.

  • [575] Do I have to use the motion driver and configuration file to use this card? The x,y,a shows that it's moving on display, but the motors aren't moving.

    Yes, the RNRMotion.dll file must be used and put in the plugins folder under the Mach3 folder.

    The XML file that I link on the Mach3 USB controller page is the file you should start with. This file will have the necessary configuration that links the Mach3 USB controller to the Mach3 control software. You can then make whatever changes you need to this configuration to tailor it to your machine.

    Do you see a quick flashing red led on the board when you press the arrow keys?

  • my motor only goes one direction. I checked all the wiring and it's correct. Any suggestions?

    The video showing the hookup of the large motors showed a sequence that was not correct, or I totally misread what was recommended. I hooked the first motor up that way and it would only go in one direction in a very jerky mode. I confirmed that i had hooked it up the way the video showed, disconnected the wiring that runs through to the motor and reconnected it, thinking maybe a cold solder joint was the problem. No good. I finally went to the motor page that showed a different connection pattern. I tried the one that the motor page said to do, and it works smoothly and in the right direction now.

  • Hey Patrick where is the video to adjust manufacturers parameters on lasercad? I watched it but can not re-find it. For pulse unit

    The latest LaserCAD video that I have is this one:
    https://www.buildyourcnc.com/tutorials/tutorial-trocen-anywells-lasercad-install

    I go over adjusting manufacturers parameters at the end of the video.

    Do you remember another video other than this one?

    Additional Information:
    I also have a video where I calibrate each axis. I go deeper into the manufacturers parameters in this video:



    Let me know if this helps.

    Additional Information:
    I seem to remember one where you did an actual physical measurement to work out the new parameters. Basically the file I put in is coming out much bigger than it should. Also, whenever I reset the settings and put the same values in to double check, it changes them again.

    Additional Information:
    I think the one I just added to this question is it. You may have been writing your response while I was adding this video.

    Additional Information:
    Yes that is the one. My settings should be very similar to yours, yes?

    Additional Information:
    Yes, it will be similar but not exact. If the microstepping is different than mine, the value will be totally different, but that is fine. As long as the nozzle goes where you expect, you will have good X and Y axis values. Remember to do the calibration with point as far apart as possible. That will make the overall calibration much more precise.

    Additional Information:
    The file is still coming out bigger than lasercad says. Says its 65mm and its about 3 times that. Also, X axis is a little joggy again.

    Additional Information:
    If the travel is 3 times farther, then it's going to be 3 times faster as well, so the motor has reached it's speed limit. The value is in steps/mm, so if you divide the value by the manually, see what happens.

  • I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

    The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

    Additional Information:
    I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

    Additional Information:
    Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.
