I've been running CNC machines since the 80's, never found the need to "home" except when forced to by software/firmware. I've never run the machine off the end of the screw, drilled the bed, hit the chuck or any other disaster or been a supporter of a nanny state. I simply put the work on the table or in the chuck, zero to the top corner, (or end of stock in lathe) and run my code. I know the physical limits of my machines and I keep within them. I also tool change at the absolute minimum distances I can get away with as wasted movement is wasted time and time is money. Only one of my machines has operational limit switches, the only times they get tripped is when I clean it <G>. I've no problems if anybody wants to use offsets, tool tables, home switches, home tool change positions or whatever, please just don't make them compulsory as there are many ways of skinning a cat ;) Steve Blackmore -- ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
