Re: [Emc-users] 5-axis table-table kinematics: G54 offsets (Andy Pugh)

I am confused with G54 to G59. Look at the following code and run it on a simulation setup with Axis C rotation added: G10 L2 P1 x0 y0 C0 G10 L2 P2 x10 y10 C0 G10 L2 P3 x0 y0 C-45 o100 sub G0 x25 y0 G1 x30 f200 G1 y5 G1 x25 G1 y0 o100 endsub g54 G0 x0 y0 C0 o100 call g55 G0 x0 y0 C0 o100 cal

Viesturs Thanks for the response. Perhaps before we go any deeper, have a look at what I have done. I Yahoogroups, under group SA-CNC-CLUB, you will find some photos of the 5-axis machine setup and the part cut. I tried to use a G54 in the GCODE for a C-axis offste - it did not seem to work.
