About G83 Deep drilling variable peck depth

Hello Everyone,

I was searching thru forum and internet for possibility of G83 deep drilling canned cycle with variable peck depth using IJK word in LinuxCNC, I didn't find any example or reference for that. 


Is it possible to achieve this thru macro ? I want to drill deeper 20xD several 100s holes in circular bolt pattern. Any guidance? 

Hole is exiting at an angle so any idea how to program slowing down spindle at every depth . 


Thanks in advance.

Doesn't seem to be supported. I also checked the code, interp_cycles.cc (always learn something new)
but no IJK.
