X home switch on positive side of travel

Hey guys me again, before I start .ini file is include and two pics of the machine so you can see position of the switch understand me (pic of cat is how I feel right now)

So as the title says my Home switch is set up on the right side of my table, and I'm trying to set up 0 to be the centre of my table. I have edited my .INI file so that min is  -111.5 and max is 111.5 (As my max travel is 223 so that should put zero smack bang in the centre... I hope?)

Problem is the machine keeps looking for the homing sensor on the wrong side of the table as in it travels in the wrong direction. I've read a few other posts and someone said that a - or + in front of the HOME_LATCH VEL will change the direction it looks for the home in? But changing that seems to not do anything.

The only way I got this to work was flipping all axis in the gui editor then it works flawlessly but... then all my parts are mirrored which I don't want.

Thanks again guys, as always hopefully Im missing something super easy -_- 

 

photos didn't work? 

The first move is done at:

HOME_SEARCH_VELOCITY

So changing the sign of this value will change the
direction of the first move in the search for home.


linuxcnc.org/docs/html/config/ini-homing.html#_home_search_vel
 

So currently HOME_SEARCH VEL is set to 1.500000

If I Change that to -1.500000 or +1.500000 I should see change in direction? Ill go try both of those right now and report back

Thanks

HOME_SEARCH_VEL is what you would negate to change the search direction.

Also check that the axis direction corresponds to the tool movement.
linuxcnc.org/docs/stable/html/user/user-...chine-configurations

axis direction is correct, and doing what PCW said fixed it straight away! I was so close just the wrong one haha! So thanks PCW!

Next problem is getting zero to now be the centre of the table looking at my .INI file is what I thought you would do but its over shooting the centre by about 30mm and then the axis gets locked out.

I want the machine to hit the home button (Which its doing now thanks again) And then move the the table centre and say THIS IS ZERO looking at my .INI file how far of from that am I? Hopefully I'm on the right path at least I'm going back to keep playing with it.

Thanks again guys progress has been made

Would you recommend just having 0 on the far left side? So it homes on the right and then flys over the left? haha had I known I was going to get into this mess I would have put the homing switch on that side my bad.

Thanks again for the help guys

Ok current .INI file included and here is a link to a video of the machine Homing and the Errors that pop up (imgur.com/a/HZ26bsn)

Ok so, so far with your help I have gotten the searching for the home in the correct direction, it hits home and then the table moves all the way over and stops right before the end and zeros out 0,0,0 on the DRO, so thats PERFECT exactly what I want.

Issue is not I get Hard Limits are reset to ACTIVE, Joint 0 on limit switch error, HARD LIMITS ARE OVERRIDDEN.

And I can only move the table close towards the hard limit if I try to move in the right direction just get errors and no movement, Can one of you kind souls take a look at my .INI and see if you see any issues? Its so close to working I'm just not sure what Im missing.

Fixed it, Re opened STEPconfig and set that signal for the sensor to just X HOME instead of X Home + Max limit and it works flawlessly.

Thanks for all your help guys much appreciated and I understand a lot better how the .INI stuff is working sucks that my brain doesn't learn to well from reading the whitepaper i have to mess it up first and slowly it makes sense chunk by chunk
