[Emc-users] Homing from Gcode and Probe

[De M. D. <da...@de...>]

Hi to All,
       i've build my CNC machine controlled by EMC2.

I am using three DC motors from old IBM printers with a home made DC 
amplifiers, home made control board (4xDACS, 3xLS7166 counters, 
32xDigital inputs, 16xDigital Outputs), and custom made HAL driver.

I've some questions regarding the EMC2.

1. Is possible to home the axis to the Limit Switch from the GCode? 
Homing from user interface in manual mode works fine.
2. Probing seems not working.
    The idea is to touch a limit swith with the tool and "measure" the 
lenght to adjust the offset.
    The limit switch is connected to "motion.probe-input".
    From Gcode i wrote the command G38.2 Z0
    The Z axis start to move to the 0 position.
    If i press the switch nothing happens, the Z axis doesn't stop but 
still run to 0.
    If i understand correctly the axis must stop (and return?) and write 
the "touch" position to variables 5061...

Thank you for your help.
