Homing Issue was created by Niskyspy

Hi All,

I can't figure out the homing configuration for my mini mill. I am using 7i96 card with LMS 3990 The axis moves at HOME_SEARCH_VEL toward the homing switch, it triggers the switch and zeros out the axis The issue I am having is that
the axis does not back off for a recheck HOME_LATCH_VEL. It just stays right in position with the switch engaged.

I've tried changing the values and sign (+/-) for HOME_SEARCH_VEL, HOME_LATCH_VEL, SCALE, HOME, HOME_OFFSET but just cant get it to work.

What version? Homing changed in V 2.8

But this is my code with seperate home and limit switches.

Code:

MIN_LIMIT = -0.01
MAX_LIMIT = 1258

HOME_OFFSET = 45
HOME_SEARCH_VEL = -100 
HOME_LATCH_VEL = 10
HOME_FINAL_VEL = 50
HOME_USE_INDEX = NO
HOME_SEQUENCE = -1

And with shared home/limit on Z axis

Code:

MIN_LIMIT = -84
MAX_LIMIT = 0.001

HOME_OFFSET = 1.0 
HOME_SEARCH_VEL = 10 
HOME_LATCH_VEL = 5
HOME_FINAL_VEL = 10
HOME_USE_INDEX = NO
HOME_SEQUENCE = 0
HOME_IGNORE_LIMITS = YES

I looked into more after work and it was a faulty switch, it would open contact for a microsecond and the close. Replaced the switch and it’s working like a charm. Love Linux CNC!!!
