The problem is that I didn't explain properly. I was meaning that you might need to pass one or both the position signals though a HAL "scale" function with a value of -1 to get the required effect (this means that the "offset" becomes "subtract" rather than "add") http://www.linuxcnc.org/docview/html/man/man9/scale.9.html Can you analyse what needs to happen to make the hand do what you want? ie, with the original one-to-one joint mapping, manually jog the hand into (0,0), (90, 0), (-90, 0), (0, 90, 0, -90) positions in (elevation, rotation) and note down the motor-position-cmd values which correspond to each position? There is only so much we can do by guessing. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
