Homing question

I want my spindle to be an axis, direction and steps are no problem, but i don't have a proximity switch for homing, but i need the spindle to have an home position, if i try to home with the encoder index on the spindle as a home-switch with slow latch and search velocity, i have to go very slow and most of the time i get latch error because the encoder index is not a proximity switch and it goes off very quickly before reversing the direction.
can i in any way disable the latch error, or having the input rise for longer than the truth?

if i try to use the encoder index as the axis index with HOME_USE_INDEX= YES and HOME_SEARCH_VEL = 0 the home gets done, but the final position is always the position where i opened linuxcnc at, it does not set the zero where it finds the index, is it normal this way?
i need the zero to be where i find the index not where it was when i opened linuxcnc, can it be done?

or since the spindle driver can home by itself, by just sending an output and waiting for an input, can i make such home with linuxcnc?

fixed, i made home without latch and search speed, used the axis.homing pin which goes on for 0,1 sec to put on the make-zero pin of the spindle driver, added a couple of seconds with timedelay to have time to make zero and it works.
Only problem i am not waiting for the input that the zero is done, zero gets done but i can't be 100% sure because i didn't read the input, any way to wait for a pin before confirming home?
