Brian somewhere im missing something and need some help.
I'm sending two files to you with simple DXF and Output Gcode.
before starting LZ i have tool number 1 with dia .25 (system set to inch), 0 tool height offset.
open LZ change holes to drill.
Layer control
tool = 1
final depth = -.25
rapid height =.25
start height = 0

Load G-code to Mach3
bring tool to work surface
zero all coordnates

start part

? why in line N9 does it try to cut at +.15 not at - 25.
When it drills the holes the machien does go to -.25
puzzled 

sent dwg not DXF

There is a new rev of LCAM (2.54) that should fix the problem that you are having It should be out in a day or so.

Thank you for posting  the info!
