Error during toolchange probe tripped during move

Hi , I'm getting nuts ,

first of all I'm Newbie , I setup linuxcnc 2.8.0 with gmoccapy 3.0.9.1, mill is working so far , XYZ , limit switches , spindle.
I setup the internal auto tool measurment from gmoccapy .

It moves XYZ to requested position , dialog for tool change is displayed , acknowledged , Z move fast down to requested position and started to slow down for measurement , so far ok.

then If I wait for the MAXPROBE distance without pressing the sensor I get the correct message (G38.2 move finished without making contact)
but if the sensor is pressed I got "Probe is already tripped when starting G38.2 or G38.3 move"

any help appreciated

ok , got it fixed , I use my "switches" for both limit and home ,
so my Z min MAX is 0 and home -5 , switches at -2.
in the macro (manual_change) was

;first go up
G90
G53 G0 Z[#<_ini[AXIS_Z]MAX_LIMIT>-0.1]

so 0-0.1 =G53 -0.1 but my switches were already triggered at -2

;first go up
G90
G53 G0 Z[#<_ini[AXIS_Z]MAX_LIMIT>-10.0] fixed the problem
