Hi,

 I'm trying to figure out Mach3 is calculating it's origin then using G68.

Example say I'm doing with G54 set to X0 Y0

G68 X1 Y1 R15

Mach3 will say my new origin is X-1.2247 Y-0.7071, but if you calculate a roration about X1,Y1 by 15 Degs the
origin comes as X0.2929 Y-0.2247.  Can anyone shed a light on this for me?

Thanks,
Tomas

Hi Tomas,
see picture.

Hi Alex,

  Thanks for drawing! I see what is going on now. Do you know why when the DRO's are
red they are showing the distance from the rotation point and not the origin location?

The G68 will rotate from the givin point in the call . IF there is no Givin point then it rotates from the point from which it was called.


Just a thought, (;-) TP
