General Mach Discussion / Re: Mach3 Windows 7 64bit with UC100- NEED HELP!!!
« on: September 28, 2015, 06:12:35 PM »
My problem ended up being defective hardware.  I had a bad board which wouldnt allow the signals to get to the drivers.  I replaced the board and one of the drivers and everything worked fine.

PROBLEM SOLVED!!!

The issue ended up being problems with the hardware.  I noticed some scratches on the C10 board.  I'm not sure if I caused them or if it came that way.  Either way, I bought a new one and the motors were able to jog again.  The problem with the Y axis ended up being a bad driver.  Automation Technologies replaced the driver and now everything is running perfect!

Thanks for everyone's help!

SmoothStepper USB / Re: ESS and Motors Stopping

Was there ever a resolution to this problem? I am having the same issue.

I grounded the drain wire on the wires coming out of the board.  I haven't seen the noise issue anymore.  Now with the UC100, I cannot get the motors to move.  Mach3 shows they should be moving.  I didn't change any of the wiring, not sure why this is happening. 

I tried a parallel cable and a different computer with Windows XP.  I can jog the motors now, but only for a few seconds.  Then the motors start skipping steps and eventually stall.  Mach3 still shows them as moving.  I am at a loss on what is happening with this machine.  I have tried different accel/velocity combinations with the same result.  If I turn off the power to the board and motors, then turn it back on, I can job again, but experience the same problem where they quickly stall out.

Thanks for the reply Rich.  I will work on getting the shielded wires grounded. 

I am using a UC100 Motion controller.  I noticed I do not see the noise issue (ie motors moving when not supposed to) when I unplug the USB.  Could it be the USB cable is the culprit?  It is a cheap cable and does not have ferite rings or shielding.

I have 18/4 wire with an uninsulated wire in the bunch as well.  The manufacturer refers to the uninsulated wire as the "drain" wire.  Is this the shield you are referring to?  The wire is shielded as well by a layer of what looks like aluminum foil.  Do I need to run the "drain" wire to ground and leave one end unconnected? 

I tried a parallel cable to see if the UC100 was the issue and I am having the same issues.  I think you are correct about noise in the system.  Now I am just not sure how to remove it.

Thanks for the tip.  I am using shielded wire on everything.  Is there anything special I need to do to ensure it is properly grounded? (other than connect the wires to the breakout board/ motor driver.)

Also, any idea why the noise in the motors would just now be starting?  It has not happened before. 

Thanks for your help!

Here is the XML file.  I believe the steps per unit are correct.  The X and Y axis are the same and the X did not have any problems, only the Y. 

I haven't turned the machine on in a couple days until today.  Odd thing happened.  When I powered up the motors they began to move very slowly and very jerky.  Hitting the estop in Mach3 would not stop them from moving.  Now, even when jogging, all motors are very jerky and noisy.  Not sure what is happening here.

I finally was able to get my G0704 converted to CNC.  I can run all the axis and they are very smooth while jogging the machine.  When I loaded the roadrunner program, the y axis sounded horrible.  It was missing steps and making a loud grinding noise.  As soon as I stop the program and jog the Y axis, it is perfectly smooth again. 

I am running at 48 volts, nema 23 on the Y with a Keling 5056D driver.  I use an UC100 for motion control.  Dell PC with windows 7.  I have turned off and on the 1/2 sherline mode, tried different kernal speeds, different velocity/acceleration.  I am currently microstepping at 2000.  I have tried 400 (the lowest setting on the driver) and the grinding sound is still present during a program.

I thought maybe the Y axis was under powered so I turned the driver up to 4 amps and it did not help.

I am at a loss right now.  Any help is appreciated!
