G76 Retract

I have master RIP environment along with 2.9 Linuxcnc installed.
When I run my existing configuration from RIP all working fine except encoder A and Z.

I have modified interp.convert.cc for G76 retract issue.
What I have done wrong?

I have fully working RPI 64 bit with 2.9 Linuxcnc. Threading at 600 RPM not any issue.
I changed your perposal in G76 retract (interp.convert.cc) So I installed RIP environment master branch.
From RIP I run linuxcnc, and select my working config. and open threading g code. Now feed stops at exact G76 line.(The same code works flawlessly in installed version).
Then I checked Hal show, encoder 0,
encoder raw counts, no value on spindle rotation.
encoder velocity, no value on spindle rotation.
encoder z no signal on index slot.

Every thing working in installed .deb version
