At most one Out pin (the kind of pin that sends out a value) can be connected to a net. The full rules for what pins can be connected to a HAL net are here: http://www.linuxcnc.org/docs/2.5/html/hal/basic_hal.html#_net_a_id_sub_net_a In your situation you should probably use or2 to turn the two estop pins into one. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
