The last info you send was very helpfull. Funny enough i was on the trace of making the Z axis to 0.1 to -100.1
but was not bright enough to se that i should turned it around on min and max limit.
I still have problems with the soft limits isent there a file where you cant change those limits. the CPU must have a place where it remember it from sesion to sesion.
In the ini file there is a VEL thing in the 0 and 1 joint bothe figures are - 5 while in the 2 joint it is 5.
What is WEL.
I thinks i am very close to make my first dry run.
Thank for all the help Henrik

These ARE your soft limits:
roughly explained: joint limits are before homing and axis limits after homing. For your case set them to the same values.
Those two velocity settings are used for your homing routine. HOME_SEARCH_VEL = -5 tells the controller to search for the homing switch in the NEGATIVE direction with a speed of 5mm/s, HOME_LATCH_VEL = -5 tells the controller to move off the switch after first detection and then move into the switch again witch a speed of 5mm/s. The position is set to zero on this, second activation of the home switch. So you can set two different velocities for homing. Fast for the first move to find the switch and then a slower move to set the home position.

Thanks. I will work with that tomorrow.
I am learning a lot from you when you tell me all those things.
I have problem with the hard limits as the CPU stops but it dosnt move away from the limits so trying to move them manualy dosnt work so i cant start linuxcnc and move the axis because the limit switch is still on.
God weekend Henrik

Doesn't your AXIS GUI have a checkbox "override limits"?
If I recall correctly this checkbox can be activated by clicking on it and then you can jog the axis off the switch. I haven't used the AXISGUI in a long time but that is how it used to work.

Once my machine stoped by limitswitch, i had to check the override limits box, then estop and enable again. Then I could jog off the switch.

Yes there is a override limits used it and smashed the limit switch.
I am working on it , changing the limitswitches, the old one some of the most expensive i could bay is not the right ones for this project.
