It doesn't. It has no sensors on it. The new position is based on the software knowing which tool is currently in "play" It is purely stepper driven. 8 positions per revolution, Drive it one way >45° and then the other way more a few degrees to drive it up against the stop, it will not drive any further that way. My Mach3 macro works along the lines of ... (simplified for explanation) Rotate A axis +ve ((NewPosition - OldPosition) *45°)+5° Rotate A axis -ve 10° > Here is what my ladder looks like... Thanks for the info. Can I use ClassicLadder to drive a stepper axis? Do I have to connect the stepgen and count the pulses I send to it? or can I just instruct it to do a GCode sequence? Does EMC automagically remember the value between sessions or do I use the external file for it to save the axis positions? (I can't remember the name of the file off the top of my head) Thanks Simon ------------------------------------------------------------------------- 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
