Hiyas,

I’m about to start milling some fairly large 800x400x400mm polystyrene blocks on my rotary 4th axis. As I usually do I did a dry run to check the gcode. I see at the start of the test gcode the command to rotate the stock material before the mill end is lifted to the clearance height i’ve set. I’d like this reverse i.e. lift to clearance height and then stock rotation.

I’m sure this is a basic one but is it something I set up in RhinoCAM or in Mach3 and how do I do that? I have safe z ticked in Mach 3.

Here is the start of the code…

G00 G49 G40.1 G17 G80 G50 G90
G21
(Setup 2)
(Horizontal Roughing)
M6 T9
M03 S7200
A-45. F10160.
G00 Z143.4785
X-26.7328 Y32.0000
G01 Z98.7135 F3200.0
Z98.0785 F750.0
X-33.7178
X-37.9425 F4000.0
etc

Any ideas most welcome

Thanks
