The DRO ALWAYS matches during jogging. It just when running code that it doesn't match the actual movement. The part that is confusing is that I'm not loosing steps, I'm GAINING them somehow???
If I tell the machine to jog 1.5": It move exactly 1.5" and the DRO says it moved 1.5"
If I use the code with a center drill in the chuck:
G00 X0 Y0 ;go to the start point
G01 Z-0.1 ;lower the tool and make a small dimple
G00 Z0 ;raise the tool
G01 X1.5 ;move the tool 1.5"
G01 Z-0.1 ;lower the tool and make another small dimple
G00 Z0 ;raise the tool
M02
The DRO says that it is at X 1.5", but its actually moved 2". I'm not gaining distance because I'm taking the diameter of the bit as part of the measurement. I'm measure the center-to-center distance between the two dimples. |
