Possibly, yes. Not in G-code, it has no way to handle arrays with curves in well (it might be possible with computed parameters, like #[100 + #1] = [sin[#2]] which is valid, but it would be a struggle. I did my eccentric turning with a HAL module which computed the required offset, and I interposed it between axis.0.position-cmd and stepgen.0….. A better solution might be a custom kinematics module. You could load it with a profile file format as a parameter, and have a wheel-radius pin which was used in the calculations of joint.0 as a function of X and A. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
