### You might use something like this to enable chopper drives when machine ON
### the Xen signal is defined in core_stepper.hal
###
# linksp Xen => parport.0.pin-01-out
###
### If you want active low for this pin, invert it like this:
###
# setp parport.0.pin-01-out-invert 1
###
### A sample home switch on the X axis (axis 0). make a signal,
### link the incoming parport pin to the signal, then link the signal
### to EMC's axis 0 home switch input pin
###
# newsig Xhome bit
# linkps parport.0.pin-12-in-not => Xhome
# linksp Xhome => axis.0.home-sw-in
# newsig Yhome bit
# linkps parport.0.pin-12-in-not => Yhome
# linksp Yhome => axis.1.home-sw-in
# newsig Zhome bit
# linkps parport.0.pin-12-in-not => Zhome
# linksp Zhome => axis.2.home-sw-in

### Shared home switches all on one parallel port pin?
### that's ok, hook the same signal to all the axes, but be sure to
### set HOME_IS_SHARED and HOME_SEQUENCE in the ini file. See the
### user manual!

### Just like the shared home switches example, you can wire together
### limit switches. Beware if you hit one, EMC will stop but can't tell
### you which switch/axis has faulted. Use caution when recovering from this.
###
# newsig Xlimits bit
# linkps parport.pin-15-in-not => Xlimits
# linksp Xlimits => axis.0.neg-lim-sw-in
# linksp Xlimits => axis.0.pos-lim-sw-in
newsig limit-reached bit # create a limit switch signal
linkps parport.0.pin-12-in-not limit-reached # connect this signal to pin 15 on the parport
linksp limit-reached axis.0.neg-lim-sw-in
linksp limit-reached axis.0.pos-lim-sw-in
linksp limit-reached axis.1.neg-lim-sw-in
linksp limit-reached axis.1.pos-lim-sw-in
linksp limit-reached axis.2.neg-lim-sw-in
linksp limit-reached axis.2.pos-lim-sw-in
###
### you can also use the "net" syntax to accomplish the "newsig" and "link"
### operations all at once. This command does the same thing as the above
### block.
