I can't tell if you're asking whether the software can do this, or whether anyone knows how to rig up the sensor. If you have the sensor and an input that you can get into HAL (through an ADC probably) EMC2 can use it to control the feed. You would hook the signal (after appropriate scaling/offsetting) to motion.adaptive-feed and then use M52 to turn on adaptive feed whenever you want it. The adaptive feed signal should swing from 1.0 (obey F word in the program) to 0.0 (stop altogether). http://www.linuxcnc.org/docs/devel/html/gcode_main.html#sec:M52:-Adaptive-Feed-Control ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
