General Mach Discussion / x axis only moves negative
« on: January 28, 2015, 03:55:53 PM »
Hoping someone can help..
My X axis works fine when using the arrows on the keyboard. right arrow x moves positive..left arrow x moves negative.
The problem is when I start the gcode. The x only moves negative. the DRO shows a positive movement, but i is traveling negative.
I am using stepper motors and a LPT BOB. Have changed BOB, but same problem. I even thru on another stepper driver and still same problem.
