Which post processor are you using? uccnc?
Can you please provide an example file + output?

[jabenetti]

I'm using uccnc as post processor. The problem is than depth is only used in first hole with G81 code:
G81 Z-10.000 R4.000 F100.000 ( FIRST HOLE, OK )
G0 X18.710 Y0.000
G81 F100.000 ( SECOND HOLE, WRONG, NO Z DEPTH )
G0 X0.000 Y19.678
G81 F100.000 ( THIRD HOLE, WRONG, NO Z DEPTH )
G0 X-19.812 Y0.000
G81 F100.000 ( FOURTH HOLE, WRONG, NO Z DEPTH )

If you add "--repeat" to args, it works.

It seems REPEAT_ARGUMENTS filters out Z-Pos because it doesn't change for the drilling cycles. There should be added an exception for canned drilling cycles.
