Accessing Interpolation?

Postby Zeppelin1007 » Tue Feb 16, 2016 5:48 am

hey guys.

So, the way we use GCode from Vectric on a rotary axis leaves more to be had. Case and point: Try the rounding gadget and the thing will bounce back and fourth, rather doing a full 360. And if you're doing 3D finishing on say a drumstick? You get TONS of Z retracts. Why? Because its simply 3 Axis code being adapted to a 4th axis.

I wrote my own wizard in mach3 that will put the tool into the material, rotate 0-360, then re-zero at A0 and continue moving. One continuous cut. It works amazingly.

This got me thinking: Anyway to access interpolation in the vectric post processors? If i want to move X0 -> X15, but output code in say 0.25" increments?
So,

G0 X0
G0 X0.25
G0 X0.50
etc etc

This way i could G0 A0 G0 A360 commands in between each increment.
G0 X0
G0 A0
G0 A360
G0 X0.25
G1 A0
G0 A360
G0 X0.50

etc etc

The thought then is, draw a simple 2D profile and have my X and Z follow it, while rotating after each increment.

Is it possible? It would save a TON of machining time.

Thanks guys
