General Mach Discussion / Y axis missing steps while running gcode, smooth while jogging

« on: March 19, 2015, 04:06:09 PM »

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!

General Mach Discussion / Mach3 Windows 7 64bit with UC100- NEED HELP!!!

« on: February 12, 2015, 09:37:52 PM »

I am running Mach3 on windows 7 64 bit.  I have a UC 100 motion controller.  Everything is wired according to the wiring diagram.  I cannot get a motor to turn during testing.  The computer is connected to the UC 100.  I have voltage at the signal side of the motor driver when I press the keyboard buttons to move the axis.

I am not sure what I am doing wrong but I cannot get the motor to turn with anything I try.

Please Help!
