Using the post-processor found through these forums (rep to martin-db, I think), I have the origin set to the lower left top surface. I didn’t review the gcode the first run and quickly realized that X and Y are moving to negative values (Z is fine).

I tried searching on autodesk for an answer but only came up with answers for troubles with Z. I am sure there is something simple I am missing.

Here are the snippets of code with negative values:

I am not sure what I fudged around with after the first run but this time around there are very few lines directing the machine into the negative (my work area is 609.6x609.6 and it was printing 300 to -300 last time).

This is not that big of a deal at this point (my machine can actually move 26 inches in x and y).

I was thinking that this might be a problem with my roughing operation, I have 0.50mm set for material to leave… thoughts?
