Michael G explained how to do this in another message, which leaves me free to spout my opinion instead! I have extensively used a (non-EMC) machine that requires a rehome after estop. In at least one case I can remember, I had a crazy setup that was in the way of homing. If I had estopped during that job, it would have been a very big pain, involving cranking the knee down out of the way and losing my origin. Even when it is possible to rehome, it is an unwelcome distraction. The result was that it made me think twice or three times before hitting estop. I went for feed hold instead - a much harder little button to hit on this machine -- and it doesn't stop the spindle. So I recommend that you fix your machine so the encoders don't ever lose power. It is such a luxury on my EMC machines to not worry about hitting estop. On both my servo EMC machines the encoders are run by the PC power supply so no matter what, if EMC stays running, the encoders do too. Now that I have written this, I notice you don't say it's a servo system. If you disable stepper amps, I guess you don't have much choice but to rehome... If this is your situation, I'll say this is just food for thought (for others) and you should ignore me :-) Chris ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
