Hi, Rob, I am not sure about that if you have received my msg, so forgive my repeating.
Your presentation of LinuxCNC trajectory planner last time sent to me is really meaningful. As you said that you would like to scan your notebook about blendmath into pdf. Do you have done ? or you have not got time to do ? Can you send me the link or pdf docs when you have finished? Thanks.
