I ran a big Shopbot gantry machine with LinuxCNC 2.5 and gantrykins. It successfully made tons of parts, but it was a little rough around the edges... Some of the things that bugged me were: * In Free mode (aka joint mode) it honors the soft limits, but in Teleop mode (aka world mode) it doesn't. * No incremental jogging in Teleop mode. * Jogging the gantry in Free mode racks it, and there's no way that I could find to forbid it. * Running MDI via halui switches to Free mode. I'm curious of the joints_axes4 branch fixes some of those problems... -- Sebastian Kuzminsky ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
