My 7i76e Connection Sheet

Did you look at the linked page?
You need to change the driver load line

i do i look at the linked page for the moment al is so confiusing
i have a system that "work" the axis move when i add this lines i got an error
witch line is it and to what do i need to change the line
one time i understand how this hal realy work it will be clear to me

In the hal line that starts with:

loadrt hm2_eth

You must change the sserial port token to sserial_port_0=20xxxx

The original hal line was omitted from your first post but it probably has
sserial_port_0=00xxxx

pcw you had it all right i made a typo and that was the reason why i couldn't get it working
rodw I used your post from 16 Mar 2018 00:00 for the axle selection and indeed I got that going now
I am very grateful to both of you for the patience you have shown
now we are going to start with the next step the tool length and the position of the workpiece

mine test setup

what can go wrong yesterday i had a working linuxcnc with jog and axil selection
today i just change the value of the z-axis puls/unit ,speed and accelreration and in got again an error from the custom.hal
Debug file information:
Note: Using POSIX realtime
./custom.hal:81: Pin 'hm2_7i76e.0.7i76.0.0.enc0.count' does not exist
4978
when i create a new installation 3 axis that work fin . when i add the custom hal this error appears again where do i have to search ?

thx for the quick replay
yes thats the solution why do it change when i configer the value of axis ?

i start a new setup with pinconfg and add for each axis an limit/home switch on input 04, 05 and 06 from the mesa
when i run the machine and start homing the axe move in the right direction but don't stop on the switch
is that what i have to expect ?
