how to rotate the same fix mesh with different origin

Hi all,
I am new with liggghts
I am try to rotate the same fix mesh with different origin and different running step
When I run a simulation which includes a mesh rotation about 2 different axis I get a different rotations in the first running, it is running fine.
But at the second running, i get the error as follows : " ERROR: Illegal deletion of a fix move/mesh. There is another fix move/mesh command active on the same mesh. Superposed fix move/mesh commands must be unfixed in reverse order of creation (fix_move_mesh.cpp:137) "

My goal is to make a rotation like planetary gear with differents axis and the angular velocity has to be change in each run

I implemented what I want to do as follows:

variable w1 equal -10.0
variable w2 equal -20.0

variable w3 equal -30.0
variable w4 equal -40.0

run 1000 upto
fix movecad1 all move/mesh mesh cad1 rotate origin 0.0 0.0 0.0 axis 0.0 0.0 1.0 period -2.0
fix movecad2 all move/mesh mesh cad2 rotate origin 0.0 0.0 0.0 axis 0.0 0.0 1.0 period -2.0

fix movecad3 all move/mesh mesh cad1 rotate/variable origin -0.35 0.0 0.0 axis 0.0 0.0 1.0 omega v_w1
fix movecad4 all move/mesh mesh cad2 rotate/variable origin 0.45 0.0 0.0 axis 0.0 0.0 1.0 omega v_w2

unfix movecad1
unfix movecad2
unfix movecad3
unfix movecad4

fix movecad5 all move/mesh mesh cad1 rotate origin 0.0 0.0 0.0 axis 0.0 0.0 1.0 period -2.0
fix movecad6 all move/mesh mesh cad2 rotate origin 0.0 0.0 0.0 axis 0.0 0.0 1.0 period -2.0

fix movecad7 all move/mesh mesh cad1 rotate/variable origin -0.35 0.0 0.0 axis 0.0 0.0 1.0 omega v_w3
fix movecad8 all move/mesh mesh cad2 rotate/variable origin 0.45 0.0 0.0 axis 0.0 0.0 1.0 omega v_w4

run 2000 upto

<<< I get follows error at 1000 step:
ERROR: Illegal deletion of a fix move/mesh. There is another fix move/mesh command active on the same mesh. Superposed fix move/mesh commands must be unfixed in reverse order of creation (fix_move_mesh.cpp:137)

mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Thanks you in advance.
