  1. Hi got the same cnc 6040 and same control panel as you and having a few problems. When the router is running it clicks every so often and also it moves out of position by anything from a couple of thou to 30mm. For example I did a circle with letters inside first cut everything OK second step down started cutting same design but missed circle by 2-3mm and then on letters was even worse.
    Please any ideas or fixes would be great.

    Regards

    Keith

  2. Hi Keith, sorry it took a while for me to reply.
    If you go to my Mach3 set up and copy all the settings, that should do the trick, if not then get back to me, and i will see if I can help you out.

  7. Hello Kev

    First I want to thank you for your input about grounding on the cnc fourm.

    Now I am really new to the world of cnc. I have been a wood worker for many years and decided to try using a cnc in my wood working.
    With all that being said I need help with grounding my machine. I have USB 3 Axis 3040 CNC Router 400W Engraver Engraving Drilling Mill Machine. I do not understand what and where and how to ground. I know I have stray noise interfering with the operation of my machine. When I run a job the mach3 software stops responding. The only way to get mach3 responding again is to unplug the usb cord and plug it back in. Mach3 only stops responding when cutting material. If I run program with no cutter than everything runs fine.
    So could you please explain how I ground my machine in a simple way so I can understand.

    Oh yes what a nice blog you have. Some good information.

    Thank You,
    Dennis Killian

  8. Hi Dennis, I know that all electrical items over 50v in the uk must be earthed. Having said that i didn't earth my spindle but i did run an earth wire from the earth terminal or post inside the control box to the frame the machine stands on and then from the frame to the frame of the machine. have a look at the photo above and you will see a wire coming out from underneath the control box. However your problem doesn't sound like earthing the spindle will help, can i ask what material you are cutting

  9. Hello Kev,
    Thank you for responding so quick.
    I am cutting walnut or maple for inlay work.
    I do get a static electricity shock from the control box. So I will try and ground the machine and control box and see if that helps.

  10. Hi Dennis, Copy the link below and paste into your browser,the yellow wire in the picture connects to the earth terminal from the 240v input socket of the control box. Then it connects to the box itself, scrape the paint off so it makes good contact

  14. Hello Kev,
    I grounded the machine and control box and now after running machine for 30 mins it stopped and the fault message said VB failure Check System. Can explain what this means. I am totally lost at this point.

    ReplyDelete
  15. As far as I know that is Visual Basic. Are you running an authentic registered copy of mach3 ? If not then I would suggest you do, the free copies that come with machines are probably pirated, and may cause computer read errors.

  16. Hello Kev,

    My machine uses usb not parallel port. The only legal copy of mach3 I have is for parallel port. Do you know if mach3 software can be changed from parallel port to usb?

    ReplyDelete
  17. Morning Dennis, if you go to the mach 3 website and ask about the VB error I’m sure someone will know the solution to your problem
    Sorry I can’t be of more help.
    I hope you can solve this as I’m curious to know too
    All the best

  18. Hello Kev,
    I have a chinese router 30x40 /Vectric VCarve, CNC USB controller/.
    It seems to work, only .... moves on the X axis in the opposite direction. Can I swap /as you write/ only the x direction or reversing the axis in Settings will help?
    Thank you in advance, István

    ReplyDelete
  19. Hi, I’m not sure I understand, when you say just the X moves in the wrong direction.

    ReplyDelete
  20. Thanks, as x value increases, the spindle goes to the "left".

  21. Hi there, have you set up your machine as shown in “my mach 3 set up” ? If not then that would be the first thing to do. Make sure you copy all the settings. If that doesn’t solve it then When I get home from work I’ll try changing some settings on my machine at home and try to help you out

  22. Hello Kev,
    for the moment I have a solution for the - probably - wiring mistake. I am carving the "mirrored" /to the y axis/ image..
    Thank you for your attention, regards, István

  23. Hello Kev,
    Thank you for all your help you have given me.
    My problem is when I start a new Pattern in mach3 and press the start button the spindle moves up to far before it moves to the first cut. I zero z axis to the surface, but when I press the start button the spindle moves up and hits the stops and this is causing my first cut to be to deep. How can I change how far the z axis moves up when the program first starts.

    Thank You,
    Dennis Killian

  24. Good morning Dennis, there are a couple of things that you can check. First go to my mach 3 settings page, scroll right to the bottom to safe Z settings and copy the settings. Then check your program. Assuming the Z height is set correctly, are you using a Z height probe

  25. Thanks Kev,

    I got it fixed. Maybe you can answer one more question.How do you program The tool change part in mach3. Right now see no way of doing a programing a tool change when I create a tool path in vcarve pro.

    And again Thank You very much.

  26. Hi Dennis, I've done a search to your question and can't find an easy way to do a tool change. However it is possible, the tool change command as you probably know is "T" so tool 2 would be T2
    Sorry I can't be more helpful, but i'm now curious how to do this
    Kev

  27. Thank you for your response. But right now I have a bigger problem. I just broke the spindle on my cnc and it is only 2mos old. So can you recommend a good quality spindle. Thanks Kev

    Thank You,
    Dennis Killian

  28. Hi Dennis as your spindle is only two months old I would contact the manufacturer, but if you damaged it yourself try an EBay search like this mini mill 400w spindle motor

  29. Hello Kev,

    I have finally got my machine running and would like to know if this china 3040 machine supports probing for a zeroing x,y and z axis. I tried to contact manufacturer and have not gotten a response. I have looked at some of the fourms but none talk about the china made machines. I really do not know what to look for. If you can can you help me determine if my machine will support probing. My machine is a 3040 with the blue control box.

    Thank You Kev.
    Have a Nice Day,
    Dennis Killian

  30. Hi Dennis I’ve just had a look around and there are some videos on YouTube of how to write the required G Code for your application

  31. Hi,

  32. Hi there, this is the machine I purchased, the only difference is mine is a 3 axis https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F253434884614

    1. But no info about diameters of X, Y, Z Sliding units.........

  33. I’m not too sure what diameters you are asking about. Are you asking for leadscrew diameters, if so then X=16mm Y=16mm Z=12mm

    ReplyDelete
  34. No, i asking about sliding units (2 units for each axes), where the bearings

  35. This is awesome��...I just purchased the same machine you have except it’s only 3 axis...I have never ran a cnc machine so it’s a bit intimidating..but I have a strong mechanical background and over 30 years fabricating,welding experience..and have always wanted a cnc something...haha...anyway I’ve been pouring over information for days and I’m trying to do this right��...first thing I want to do is install limit switches because I fear running to the end of the ball screws resulting in broken or burnt parts...I’ve located the area of the plug you have mentioned on the parallel break out board but need more info...could you please email me so I can better ask you how to go about wiring these switches?....it would be very much appreciated!.....my email is ..sbjuke@chartermi.net.

    2. Thank you...yes that did help...and I’m assuming the a axis pin can be used as the z probe?......I also read somewhere that the limit switches have to be wired n/o because of this board....just wondering why they couldnt be wired n/c....

  36. Hi Steve you can change the way the probe works like this. Go to my mach 3 settings page, link below, scroll down to the probe and tick the active low box

  37. I'm curious to find out what blog platform you happen to be using? I'm having some small security issues with my latest website and I'd like to find something more safeguarded. Do you have any recommendations?

  39. This design is spectacular! You most certainly know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost...HaHa!) Wonderful job. I really enjoyed what you had to say, and more than that, how you presented it. Too cool!
