All options are available, but not all options have been "interesting" enough for anyone to document them. :-) If the Stepconf Wizard doesn't offer the option (I haven't used it for some time) then you can edit the .hal file that it produces to suit. ie, assuming that Pin 11 is the "all limits and all homes" pin then set it to be the combined pin for the X axis and then edit the hal file to combine all the axes on one pin. Something like: net all-homes-and-limits parport.0.pin-11-in-not => axis.0.home-sw-in axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in axis.1.home-sw-in axis.1.neg-lim-sw-in axis.1.pos-lim-sw-in axis.2.home-sw-in axis.2.neg-lim-sw-in axis.2.pos-lim-sw-in (All on one line, ignore any spurious line wrapping). You will need so assign a home sequence number to each axis so they can home one at a time or EMC won't know which one has hit a limit. Note also that this might not actually work, I have not tried it. You might need to use some slightly more clever logic (AND functions or similar) to prevent inactive axes faulting when another homes. However I think that limits should be disabled during homing by default > 2.

There is probably no way to do it in Stepconf, but there should be a way to do it in manually-coded HAL. You should be able to set a pin high when axis accelleration is over a threshold. -- atp ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
