Sorry this is probaly a very basic question but I am stuck.
I am using a 6mm bit to drill two holes at 15mm centres, then ream them out slightly to 6.8mm. The first hole is fine, but as soon as it hits line 12, it travels back to the first hole to do the reaming. How do I hold the coordinates (line10) for the 2nd hole reaming action?
Any help greatly appreciated.

1. (Hole # 1)
2. G00 Z0 F60
3. G00 X0 Y0 F60
4. G01 Z-5 F60
5. G00 X.4 (ream out to 6.8)
6. G03 I0 J0 F100
7. G00 X0 Y0 Z0 (back out of hole)
8. (Hole # 2)
