Title: Have issues with my X axis need troubleshooting help!
Post by: Big Country on January 29, 2015, 09:52:58 PM

I am very new to CNC forgive me if my terminology is not correct

I left my machine today for twenty minutes or so and my x axis went postal. It jogged all the way to the left and that is how i found it.

my left arrow key on my keyboard moves my X axis left as it is suppose to. and when I hit the right arrow key it moves to the left also.

In mach 3 program my arrow keys show normal working negative and positive in the display.

I swapped my cables on x and y axis to see if it was the motor, it was not.

I have not had any problem with my cnc machine until today, I have using it for two months now.

Can anyone help me trouble shoot this Problem. Running Mach 3, my G code was generated in Artcam,

Thanks...

When I had a problem like this it was because a wire had come adrift between the breakout board and a stepper driver, resulting in all pulses looking like left pulses.  Check the wiring to the x driver very carefully.
