    help please

    Ok here is my problem. I am using a c-10 break out bord my drivers are kl-6050 and my steppers are kl23h284-35-4b. my power supply punts out 45 volt 4.0 amps. I have habe recently moved them to a diffent machine and get no movement. they worked on the old machine and the are hooked up the same way. for the life of me I can not figure out what is wrong any idea?

    The first things that I would check would be the Mach3 ports and pins configuration and the LPT1 port address.

    Then I would try to verify that when you jog an axis manually in different directions, the voltage on the direction pin of the C10 (for that axis) switches between +5 volts and 0 volts when the direction changes. If you can see that working OK, it means that Mach3 is probably talking correctly through the LPT port to the C10. If you can't verify that, then you would have to focus on something wrong between Mach3 and the C10.

    What operating system are you using on the new computer? Is it a 32-bit or 64-bit operating system?

    Maybe I misunderstood you - did you move to a new PC or did you move the steppers to a different CNC machine?

    How do you know that your power supply is only putting out 1 amp, and that it used to put out 4 amps?

    When you power up your equipment, do the motors make any noise? Do they get warm?

    sorry If I wasn't clear I tend to ramble a bit a say nothing . I moved every thing to a new machine my old one was a hand made one from junk parts and it never would cut straight. my fault really when I welded the gantry I used a mig welder because I didn't want to wate for a tig to open up. any way I bougt a harbor freight mini mill then the conversion kit to convert it to cnc. I am using the same pc and I didn't disconnect any thing in the move to the new cutter.

    as to the the measuring of the amps I used a dummy load that I ave for measureing amps up to 100 amp and the most it would put out was 1 amp when I did this before on building the old cutter it measured 18 max. I use to fix electrons as a side line business so I still have some of the equipment left of and it has helped me a lot.

    OK, I understand a bit better now.

    The power supply is certainly suspect, since its behavior obviously changed.

    I don't think that you can necessarily blame a grounding problem, because presumably when you put the load on the power supply to make your measurement, you would have connected it directly to the output terminals, and still you detected a problem.

    So, substituting a different power supply would make sense. Perhaps something went wrong (bad capacitor, bad internal solder joint, debris got into the power supply, internal potentiometer had a defect, etc.), although it may be easier just to change power supplies rather than to get bogged down in a possibly futile attempt to troubleshoot and repair the proximate cause for the problem.

    However this would also be a good time to review the configuration and hookup of your entire system, starting from the computer, Mach3 setup, LPT port, and connection to the C10 breakout board, and then on to the connection to the driver and the motor wiring (along the same lines as what I described in my first post).

    Even though you don't think that anything else was changed from your original setup, it's a good idea to double check everything.

    That is a good point, and some thing I did not do. We moved houses at the same time so I guess it is possible that wires got pulled out. as for the power supply I forgot to mention that it is 4 Pc power supplies daisy chained together and has always worked for me in what ever I have needed them for. I am disabled and cant afford a proper power supply to run it I had planed on using my cnc to make money to help make up for the lack of funds my disability check doesn't give. I went from $4000.00 a week America while I was working as a cnc laser team leader to $949.00 a month American. so it is rather important with the cold weather I get this working asap. I am trying every thing you suggest with hast and am greatfull for your help. Who said shivery is dead

    Hi

    I expect on three of the four power supplies you have disconnected the internal link from the common 0V (black wires) connection to the earthed case ,so all the metal cases are still earthed ?
    this avoids disconnecting the earth from 3 of the power supplies cases

    with 4 random ATX power supplies you may find some work
    once you connect the green power on wire to a 0V blackwire

    others will need a load resistor of 5ohm 10W to 10 ohms 5W across the +5V
    output ( red and black wires)

    are you sure all the power supplies are working OK ?

    on a 300W power supply I'd expect to be able to take about 14A
    from the yellow +12v wires

    John

    Thanks I think that may be my problem On the old machine it worked just fine with out the loads but this new one is much stiffer so its going to take more juice to move ime headin out to the garage to add the loads to the 5 volt lins Ill let you know I will also double check all my wiring thanks again
