Sherline 4-axis mill with Mach3
I ran a gcode of a 4 axis toolpath and noticed that wherever the A value decreased even a fraction of a degree, the A axis made a full revolution less the degrees of the difference.
To clarify....if the code was A310 going to A312, the rotary axis would move clockwise for just those 2 degrees (cool) but if the code was A310 going to A308, the A axis would rotate clockwise for 358 degrees.
The little test I want to run has hundreds of line with decreasing A values. How do I prevent an almost 360 degree clockwise rotation of the A axis if a 2 degree counter-clockwise rotation would do the job more efficiently?
The A axis, works correctly via keyboard input.
EDIT: I found it. Un-tick ROT 360 ROLLOVER...Right?
