General Mach Discussion / Re: Save Z - Beginner - To many options - Simple but not for me

The surface of a wood that I've been cutting in 2.5D was uneven, and since there was a lot of material on the back side, the whole model was "sunk" for 1mm.

It is not "saVe Z" but "saFe Z".
In Vectric:
Z1 Clearance is height above material Zero (top of material) for rapid movement (G0) to avoid any clamping of your material.
Z2 Plunge is height above material to which your tool will be plunged at rapid speed (G0) before switching to programmed plunge speed (G1).

For Safe Z in Mach3, you should do some reading (Mach3 manual, no link at the moment).

And please, take look at the attached picture. If it does not make all clear, then sorry

Tango PCB exports .dxf in imperial units. If your machine is set in metric units, be shure to add G20 at the beginning of your G code.

For sign making you can use Vcarve Pro and for carving crests an like, Aspire, both from Vectric.
As far as I've been "playing" around, I've found that Lazy CAM is not intuitive enough for me to use.

I use Aspire for all my G-Code generation and 2 1/2 D modelling.

Finished Plugins for Download / Re: Excellon to GCode converter plugin with Camera view ( good for PCB drilling )

Well, more suggestions:
Something is wrong with your optimization, actually it un-optimizes time to finish the drilling.
Statistics:

Optimization UnChecked:
Machine Time: 33:48
Cutting Time: 13:24
Rapid Time: 18:54

Optimization Checked:
Machine Time: 48:30
Cutting Time: 13:24
Rapid Time: 33:26 <====

GalBlastMMrel.txt is the input file, Happy.nc is file without optimization and HappyOptimized.nc is the slowest one.
