Hi all, I don't want to distract everyone from EMC2.2 but I've done some fun stuff in TRUNK (pre-2.3) with probing. I don't think many people are using probes but I know some are, and they might like to try it. I'd appreciate any reports of success or failure.
There are some new Gcodes documented here: http://www.linuxcnc.org/docs/devel/html/gcode_main.html#sub:G38.2:-Straight-Probe which allows much smarter probing without all the wasted motion. I tweaked gridprobe.ngc into smartprobe.ngc: http://cvs.linuxcnc.org/cvs/emc2/nc_files/smartprobe.ngc?rev=1.1 and the results are something like this (the program preview is turned off, and the purple lines are the backplot): http://timeguy.com/cradek-files/emc/smartprobe.png http://timeguy.com/cradek-files/emc/smartprobe2.png Connecting those points gives this path: http://timeguy.com/cradek-files/emc/probe-results.png This example was 2500 points probed in about 20 minutes. It's often doing several points a second. I also added probe protection, so if the probe trips when there is NOT a probing move going on, the machine stops. I think with these new G38.x primitives there are a lot of smart ways you could probe a shape. If you write one let us know!
