> If not, would it be useful in a future version? Very. Never used a control where holding the cycle start in moves things back to the orginal location, but it sounds interesting. The ones I run just move on to the next programmed block fine if it is a G1 move and in absolute mode, but can cause problems with G2, G3 moves or if the G code is in incremental mode. Also most of the machines I have run the operator needs to remember to turn on the spindle, the machine builders pass it off as a safty issue. I think it is just a good way to break end mills. Since EMC needs to use computer keyboards the procedure may need to be somthing like. Push cycle start to put the spindle, coolant, air blast, etc. back to original condition. Push again to move back into positon. Push a third time to get the program running. Also note that EMC does not use a cycle start, feed hold, and a toggle switch for auto single block like most commertial machines it has cycle start, pause, single step, and restart buttons I think that is what they are called. > Not a show-stopper for my current EMC application. >P.S.
