that is exactly correct for conventional 4/5 axis control if you want to simplify the programming you can develop kinematics for the machine this will allow simple programs to do complicated motion - it is not necessary for 5 axis motion - sometimes it is not desirable
to get where you need to go right now having the post processor do the kinematic calculations is probably best you will always be able to start the machine with separate ini files to use posted kinematics or 'in the control' kinematics On Tue, May 3, 2011 at 1:48 PM, Steve <[email protected]> wrote: > Stuart Stevenson replied "agreed - the "kinematics" is in the g code > program > - just having the machine control the axes is enough to be able to cut 5 > axis parts" > > I was under the impression that the kinematics had to be written in EMC2 > for > the coordinated movement between all the axes to function properly? > However > what you say seems to make more sense.
