So connect them to the Parallel port and make sure they work when you check them in the "Show Hal configuration" inside LinuxCNC.
Some general information:
linuxcnc.org/docs/2.8/html/config/ini-homing.html
Then you set it up for each [joint] in the ini file

Ok, maybe best for you to attach your .hal and .ini files. Do you know where to find them and how to attach them here?

Ah yes, so you did. What pins on the parallel port are the signals from the switches coming in on?

So, add this to your HAL file:
This to the appropriate [JOINT] sections of your INI file:
in [JOINT 0] and [AXIS X] sections you will need to change the Limits to:
Then for the homing:
[JOINT 0]
[JOINT 1]
[JOINT 2]
You will have to fine tune these settings:
linuxcnc.org/docs/html/config/ini-homing.html
[edit]
This assumes that your switches are normally open.
net both-home-x <= parport.0.pin-13-in
net both-home-y <= parport.0.pin-12-in
net both-home-z <= parport.0.pin-15-in
net both-home-x => joint.0.pos-lim-sw-in => joint.0.neg-lim-sw-in => joint.0.home-sw-in
net both-home-y => joint.1.pos-lim-sw-in => joint.1.neg-lim-sw-in => joint.1.home-sw-in
net both-home-x => joint.2.pos-lim-sw-in => joint.2.neg-lim-sw-in => joint.2.home-sw-in This to the appropriate [JOINT] sections of your INI file:
in [JOINT 0] and [AXIS X] sections you will need to change the Limits to:
MIN_LIMIT = -0.1
MAX_LIMIT = 390.0Then for the homing:
[JOINT 0]
HOME_SEARCH_VEL = -5
HOME_LATCH_VEL = -5
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 2
[JOINT 1]
HOME_SEARCH_VEL = -5
HOME_LATCH_VEL = -5
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 1
[JOINT 2]
HOME_SEARCH_VEL = 5
HOME_LATCH_VEL = 5
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 0
You will have to fine tune these settings:
linuxcnc.org/docs/html/config/ini-homing.html

I have changed what wrote plus i have changed the y axis to .1 and 590 as the bed id 60cm
I am i doubt what about the Z axis.
see the Att. thats how the HAL and INI file looks like now.

You need to delete these lines in your HAL:
net home-x => joint.0.home-sw-in
net home-y => joint.1.home-sw-in
net home-z => joint.2.home-sw-in
Then click the home button and report back.
net home-x => joint.0.home-sw-in
net home-y => joint.1.home-sw-in
net home-z => joint.2.home-sw-in
Then click the home button and report back.
