Assuming you unplug the rotary axis when you remove it, you could simply use a normally closed homing switch that unplugs with the axis. Problem with this is it wouldn’t let you use the fast approach, slow home sequence with a single switch.

The simplest is probably to set it for immediate homing (home search velocity zero) but have it in the homing sequence. If you want it to physically home when present, but not home when absent, automatically, then it's harder. I imagine that some HAL logic to detect presence or absence and a mux2 to switch between real and simulated home (wcomp looking at apparent position of the stepgen?) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emcemail@example.com https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emcfirstname.lastname@example.org https://lists.sourceforge.net/lists/listinfo/emc-users
