Florian, EMC2 can do that. I corrected the perpendicularity of the linear axes and also the misalignment of the rotary axes A and B. The X, Y and Z axes are not mechanically orthogonal. The axis of rotation of the A axis is not exactly parallel to the X axis. The axis of rotation of the B axis is not exactly parallel to the Y axis. I have a kinematics file that does these corrections. Under this directory http://www.mpm1.com:8080/cinci/cinci_running you will find the files that configure my Cincinnati 5 axis hydrotel retrofit. The cincikins.c file has the orthogonal (what I call skew) correction. Look in the file for skew. The gear4.comp is for the 4 speed gearbox on the spindle. Try this: Grab your left earlobe between your left thumb and left index finger. Grab you right earlobe between your right thumb and right index finger. You now have the limitations of EMC2 between your hands. :) Have fun Stuart

Money and goods are clearly not the same things, but are exactly opposite things. Goods are wealth which you have, while money is a claim on wealth which you do not have. Goods are an asset; Money is a debt. If goods are wealth; money is clearly not wealth, it is negative wealth, maybe even anti-wealth. – Quigley, Tragedy and Hope, pg. 44 (emphasis added) ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
