INI Confusion Joint numbering

Hi
im on a 5Axis TCP the Trivial Workes fine XYZAC
so im Adviced to see the VISMACH example
github.com/LinuxCNC/linuxcnc/blob/master...ilting/xyzac-trt.ini

here the numbering is straight BUT there is B inside the XYZAC Mashine as joint_4 // C is joint_5
and Vismach gets C as joint_4
HALCMD = net :rotate-c joint.4.pos-fb xyzac-trt-gui.rotate-c

This is taking my head of the System
as the Simulation Work fine on AC

PLEASE give me a Answer on this setup

REAL Machine is there a advice on Homing Sequence First Liniar last Rotary
as i learned the machine needs to homed to almost the Rotatet Zero and nearest save Liniar to work prober
otherwise the Jog axis fails as the Rotarys are not at Zero AC as
after Homing all axis move TCP on a Tilded rotary A or C

here is the running TRIVIAL INI
that is to be converted to TCP
i

Isent there Somone of the Moderators that can explain this
i wont play around on a real machine as 5 Axis crashing is not a good idee at all

thank you
there is a switch kinetics for selfcompiling for a AC 5Axis
how do i compile the C file
can i use DEV halcompile or do i need a gcc
im on Debian 9 and 2.9 from buildbot
