### 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, invert it:
# 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-10-in => Xhome
# linksp Xhome => axis.0.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!
# newsig homeswitches bit
# linkps parport.0.pin-10-in => homeswitches
# linksp homeswitches => axis.0.home-sw-in
# linksp homeswitches => axis.1.home-sw-in
# linksp homeswitches => axis.2.home-sw-in
### sample separate limit switches on the X axis (axis 0)
# newsig X-neg-limit bit
# linkps parport.0.pin-11-in => X-neg-limit
# linksp X-neg-limit => axis.0.neg-lim-sw-in
# newsig X-pos-limit bit
# linkps parport.0.pin-12-in => X-pos-limit
# linksp X-pos-limit => axis.0.pos-lim-sw-in
### 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.
# newsig Xlimits bit
# linkps parport.pin-13-in => Xlimits
# linksp Xlimits => axis.0.neg-lim-sw-in
# linksp Xlimits => axis.0.pos-lim-sw-in
### alternatively for this example you could use the "net" syntax
### to accomplish the same thing, all at once
# net Xlimits parport.pin-13-in => axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in
