12:28 PM jasen: Hi all
12:28 PM jasen: I think there is a bug in the homing procedure , specialy at home index only
12:28 PM jasen: in fact , when send it to home ( rotary axis) with index only , without home switch it start rotaiting up to the limit of the axis in the ini file without get it homed , releasing limit error. any attempt after this will home the axis till the power is off
12:29 PM jasen: home switch is not a good idea on rotary axises as it will be hit many times
12:29 PM jasen: and here is the ini part
12:29 PM jasen: [AXIS_C]

12:30 PM jasen: limits are extended over 360 degree for testing purposes
08:00 PM cradek_: http://linuxcnc.org/docs/2.8/html/config/ini-homing.html
08:01 PM cradek_: for index-only homing you need HOME_USE_INDEX=yes, but you didn't show that. is it set right? is your index actually working?
08:02 PM cradek_: oh, he left. sigh.
