Please read careful and enter exactly what we told you!
HOME = -10.000
HOME_OFFSET = 0.5
HOME_SEARCH_VEL = - 8.0
HOME_LATCH_VEL = 0.5
This are the setting in your case, SEARCH and Latch need different directions
You do not need a HOME_FINAL_VEL entry, if not used, max vel will be used.

. With the config
I get the following error (10 changed to 14):
What happens is that it moves towards the switch (right direction) and then stops once it hits the switch. It does not move further. I also tried with HOME_FINAL_VEL being negative - although it states in the documentation linuxcnc.org/docs/devel/html/config/ini-...html#_home_final_vel that it has to be a positive number. But the error is the same.
Withthe axis moves towards the wrong direction.

Ah, once I looked at the source I think I know where the problem is!
This is the place where the first message is thrown:
It should not throw this message because HOME_IGNORE_LIMITS is YES in my config. However it does.
This is my config:
As you can see there is no line break at the last line - which is HOME_IGNORE_LIMITS = YES. So I think the missing line break is the problem. I'll try and be back in a minute.

That it was
! Once I added a line break after the last line homing works with this config as expected:
Thanks a lot to everyone who helped! Have a great sunday!

Hi,
glad you found it, I would never ever have looked at this!
My last lines are normally the spindle settings, so I might not have seen this behavior.
By the way, why do you have 4 digits in the DRO, being in metric mode?
Do you know it can be set on the settings page?
