    Default 6040 Help

    Hi All
    New here and need some help

    I am a gunsmith and have purchased a Chinese 6040 router for cutting aluminum for jigs etc.
    My problem is :

    I am running mach3 on Windows 7 pro 32 bit
    I have no X axis movement but Y & Z are fine

    Connection is Parallel port

    Disconected X axis cable and connected it to Y axis outlet and it moves fine
    Put Y axis into X axis outlet and agian nothing

    Any help would be greatly appreciated
    Thanks Rodd

    Did you change the connections at the box, or at the motors? likely the cable inside that cable chain.
    Sounds like a cable issue. I had to replace all three x, y and z cables on mine, did it over a couple months as each failed.
    Can you ohm the cables?
    Are you hearing a grinding sound but it does not move?
    Can also try manually moving the x axis to middle, or other end, enable power to driver then see if the cable randomly makes connection and moves.
    If I may give some advice, buy enough to replace all three at once... they are a very weak point of the system.
    They can be found on amazon, both 4 conductor shielded cable and the connectors they use.

    Another note, you may need to check your settings if you are having issues with reliability.
    My machine would lose counts with small increments, it was due to the configuration being incorrect coming from the supplier.
    2 ways to test if you lose counts.
    1) try to jog with F=6; if you hear a grinding sound but see no movement, you are likely losing counts.
    2) set up a job to run 150mm in one direction, and 1mm in the other (x,y) or (Y,X). the axis on the smaller direction will likely not move at all.
    If you are not having issues, do not change anything. If you appear to start losing counts, follow this guys advice.

    A couple notes, he put in his own limit switches, if you do not have them, do not enable those.
    Also, he has a setting to make the screen full size, I did not like it and changed mine back.

    Hi Thanks for the reply

    I have changes the connections on the control box
    I pluged the X axis into the Y axis outlet and the moter moves perfectly when using the Y axis jog buttons

    I then plugged the Y axis into the X axis outlet and nothing moves when using the X axis jog

    I used a ohm meter on all the X axis connections and all perfect

    There is no noise at all when X axis is in the X axis outlet Mach3 DRO moves when jogged but no motor movement or noise
    The cable have all tested OK
    I loaded a Gcode that was a 100mm square and ran cycle
    The Y axis and Z axis responded perfectly but again no X axis

    I have uninstalled mach3 and reinstalled a couple of times to make sure it was all good


    Could it be a faulty control box (X axis Outlet) ?

    Thanks For your help

    Rodd

    it could be a poor / missing connection between the breakout board and the X axis driver

    do you have a 3 or 4 axis control box ?

    some of these control boxes use a TX14175 breakout board
    I have traced the circuit for while fault finding for some one

    6040 Help-6040-controlbox-vfd-wiring-jpg

    when the power is on
    is the motor connected to the faulty X axis locked or is it free to rotate by hand ??

    if the motor is locked
    you could try unplugging the Y axis ribbon cable from the Y axis driver
    and plugging it in to the X axis driver
    to see if its the X axis driver that's faulty or its not receiving the step signal



    note -
    the spindle control board will be live !!
    and the 5 pin chassis plug used for the spindle motor connection is a shock hazard
    when the cable is not connected

    some control boxes have the "BOB" & 3 axis drivers combined on to one PCB
    it saves on the interconnection wiring but makes it more expensive to replace when one of the axis driver IC's has been damaged

    Hi thanks for the info

    I have a Four axis control box

    When the power is on the X axis motor has power (locks up)

    I have plugged the X axis into the Y axis outlet on outside of control box and I get X axis movement
    When I plug the Y axis into the X axis outlet I get nothing

    I changed the conections inside the control box Plugged the X into Y and Y into X
    When I used the Y jog the X axis moves but when I use the X jog nothing again

    I plugged the fourth axis in today as I had not done that and it also works fine

    Its only the X axis that has no movement but is getting power to the motor

    I have attached some photos of the inside of my control box

    perazzi, from all the test and info you done, it looks to me to be the driver with the issue. Check your x driver and compare all the connections and flip switches or same as your y driver. If it is your x driver you could use the driver for the 4th axis to get you going until you get another driver.

    Thanks
    When you say "Driver"
    Is that the board withe jumper switches?

    The x axis and y axis switchs are set the same ?

    To use the fouth axis driver for the time being do I do the following ?

    1. Set axis switchs to same as x axis
    2. Set the A axis in mach 3 to x axis pin numbers ?

    Thanks again Rodd

    I would make note of the switches for A so you can put it back later and just move the x wires to the A driver ,

    That`s exactly the same on our units, did you copy/paste the mach3mill XML file that came together on the CD? copy/paste that in mach3 folder then voila!! everything will be factory calibrated in seconds

    looking at the photos your 4 axis control box is more or less what I expected

    as you have checked all the motors and the external wiring is OK

    assuming the stepper drivers are wired in the order I expect
    what happens when you swap the 3 wire ribbon cables between the X & Y axis drivers ?
    6040 Help-tx14207-connections-3-jpg

    if the fault moves to what was the Y axis driver the problem is associated with the BOB ,and its wiring or Mach3's ports & pins setup

    pins 2 to 9 in mach3 the ports & pins should
    match the BOB connections
    which it does in picture 3 in your first post
    6040 Help-tx14175-bob-step-direction-connections-jpg


    6040 Help-tx14175-bob-jpg

    note-
    after re reading post 6

    it looks like there is a problem with the X axis step & direction signals (pins 2&3)

    it could be the X axis 3 wire ribbon cable -
    they don't always get a good crimped connection on the cables !

    remove it and replace it with the A axis ribbon cable
    to connect the X axis BOB connection to the X axis driver

    the other cable to check is the printer cable



    if the X axis driver did not not respond to the Y axis step & direction signals
    then you either have a faulty driver or a problem with the connections to the 4 pin chassis plug to the motor

    one broken or disconnected wire to the motor would prevent the motor from stepping
    but the one energised coil would lock the motor

    Just throwing this out there. It looks like you have two different types of config for the switches.
    It seems to me that the x axis should be set up like the y and z, so you should have three motors with the same switches, and the a axis with its own
    Is your x axis motor the same as the y and z? It may be possible since the x axis was configured wrong it burned up the controller?

    Can anyone verify if it is possible the x axis could burn up if configured like the a?

    good point

    from another post I replied to ( I can not find the thread at the moment)

    some one found the switch settings for theTX14207 stepper drivers to be
    6040 Help-tx14207-dip-switch-settings-jpg
    the settings imply the machine had 3 identical motors for the XYZ axis
    and the A axis having a different torque setting for a different motor -
    (A axis needed more motor current )


    I have noticed in photos found in other postings have different switch setting

    note - the GAL in the table is a logic IC that modifies step direction & enable signals from the BOB and torque TQ2 switch (motor current ) control inputs to the TB6560 stepper IC
    this an attempt to correct a design error with stepper drivers without the GAL IC


    John

    PS
    incorrect switch setting would only damage the stepper driver if you set too high a current and damaged the motor

    is there any part numbers or data on the motors to find out what the current should be ?

    does the X&Y axis have motors the same size but the Z axis have a smaller motor ?

    Hi all

    When i swap the 3 ribbon conecters I get perfect X axis movement when I use the Y axis jog button

    When I changes the switch on the A axis to be the same as the X axis and connected the X axis cable to the A axis outlet I got very slow X axis movement to the right only with no left movement

    so when the ribbon cable is swapped as in the 1st picture in post 13

    the Y axis signal from the BOB operates the X axis driver & motor
    but the X axis signal plugged into the Y axis or A axis stepper driver does not work



    unplug both ends of the original ribbon cable that connected the X axis signal to the X axis driver and put it to one side


    remove the ribbon cable the is connects to the A axis BOB connector to the A axis stepper driver

    now use what was the original A xis ribbon cable
    to replace the original x axis ribbon cable and connect the BOB's X output to the X axis driver

    what happens now ??

    Hi

    Replaced the X axis 3 ribbon cable with the one from the A axis
    Re started everything still no X axis


    This is driving me mad

    Thanks for your help so much

    I Just changed the conections inside the controller box

    I switched all the X conections to the Y board and the Y conections to the X board

    I got perfect x axis movement when using the up and down arrow keys on keyboard but nothing on the Y

    in addition to the BOB , one thing not tested so far is the printer cable

    what test equipment do you have - a multimeter ?


    If I am correct , the wires used for the E-stop switch could be used to temporary connect the supply the BOB to bench test it ??

    I don't think it would be easy for you to test the break out board while its inside the control box
    from what I remember seeing the under side of the BOB is too close to the top of the enclosure

    its a pity you don't live in the UK
    it would easier for me to test it for you

    with the BOB removed from the control box and
    just a 12 to 24V DC supply connected to the BOB
    it will be easier to test the signals on the printer cable pins and
    the corresponding signals on the output connections to the stepper drivers
