To use multiple joints for an axis letter with xyzac-trt-kins,
you need a very recent (after 19jun21) build of the master
branch which incorporates:
github.com/LinuxCNC/linuxcnc/commit/135b0ce52
Suggest:
0) install current master branch from buildbot
(or build as RIP)
1) first test the demo config:
select the demo xyzac-trt config from the directory:
configs/sim/axis/vismach/5axis/table-rotating-tilting
$ linuxcnc xyzac-trt.ini
2) Copy the demo ini file:
$ cp xyzac-trt.ini test.ini
3) Edit the test.ini file to specify coordinates=xyzacy for:
x: joint_0
y: joint_1,joint_5
z: joint_2
a: joint_3
c: joint_4
Example modifications:
[KINS]
KINEMATICS=xyzac-trt-kins sparm=identityfirst coordinates=xyzacy
JOINTS=6
...
# modify JOINT_1 for HOME_SEQUENCE:
[JOINT_1]
HOME_SEQUENCE = -1
...
# new section for JOINT_5:
[JOINT_5]
HOME_SEQUENCE = -1
...
Attached is an example test.ini
