Has anyone made a 4 stroke CAM grinder using LINUXCNC. Apparently positioning the head is not the way to go. From what I was told the head needs to be positioned with acceleration rather than absolute position. It sound a bit odd but apparently if you have done this before, you have an idea of what I'm talking about.
Thinking about it, the grinding head will have rapid amounts of accelleration and decelleration during the CAM grinding cycle, so unless the PID loop is very fast and accurate and enough power to overcome the large inertia, it won't grind correctly. It could grind correctly and with lot less power if the control system had next move predictive option Cheers Wallace ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
