All limit switches on one input

Hello,

i make my first steps with linux cnc and i have a problem.
My limit switches are connected in one line to one output on a 7i96s board. In the pncconf i selected the "all referenz" option for the input.
When i start homing in cnc and the switch is reached, all axis are blocked and the machine stops.

I dont know how to set the settings, that all switches are acitvated succcessively.

I hope, that anybody can help me.

 
 

Not sure about the homing sequence, but I would expect to home Z in the up (+) direction
a (-) search direction (towards the table) seems dangerous.

Try the LUT5 component:

It should be configured automatically if you create a configuration with stepconf and choose shared home and limit switches

Hello,

All my switches are connected in series as openers.

In the INI you have to assign a number for the pure sequence for the referencing for each axis "HOME_SEQUENCE = 0 for Z" and so on.
z-axis:
MIN_LIMIT = -202.0
MAX_LIMIT = 0.001
HOME_OFFSET = 3.000000
HOME_SEARCH_VEL = 30.000000
HOME_LATCH_VEL = 1.85
HOME_FINAL_VEL = -5.000000
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 0
VOLATILE_HOME = 1

First important is Z so that the spindle doesn't scrape across the table.

And you have to make sure that the respective axis moves a little way away from the switch (move freely) otherwise the machine cannot recognize which signal is the next axis.

It gets a little more complicated with two drives per axis.
