I am having problems with me feed rate [rotation speed on 4th axis]. When I export my tool path files the a axis rotation speed is not translated and is moving very slow as a result. When running a piece the movement along the y axis is unhindered however when a rotation of the a axis occurs i takes between 3-8 seconds to complete a movement that should take less than 1 second. I know the problem can be fixed by adding to or editing the post processor file. Here is a copy of my post processor. Any and all help is greatly appreciated.
