I think check the keep tool down in depth cuts, if I understand what you are doing. Then it never goes up to Z0. However I just discovered it still wont rapid down second pass. It wont in 9 either.

I think what I used to do was put a fast plunge rate for this case.

Thats no good kepping tool down gouges when returning to start of contour.

 

Take a straight line drawn at Z0.

Countour it to Z-100. with depth cuts -2.

 

I want the tool to retract to Z5. after each pass, return to the start of the contour, then rapid to Inc Z1 of the next depth of cut.

rapids up to .05

rapid to start

rapids down to pass 2

feeds pass 2

etc. till pass 4 Done.

 

I am working in english units and only took 4 passes.

gcode,

All of geom are solid edge curves so I want to leave them where they are.

 

So say all contour Geom is the start of the cutting depth, now from there I want to go 10mm deep at 2mm deepth of cut.

 

What I want is the tool to retract above the geom but rapid back down to the new depth of cut and not feed from the geom or Top of stock.

It feeds down from the retract height. There is no Inc rapid to 1mm above the next depth of cut as per the toolpath parameters. Backplot shows a Inc rapid though?

David,

 

Try using clearance AND a retract.

 

I'm pretty sure your lack of use of the clearance move and relying solely on the retract is why you're not seeing the usual behavior many of us do.
