G71 for slot milling on lathe

[Rockbobster]

machine NL6000 XLM
fanuc series oi-tf

PS0325N CIOMMAND NOT IN SHAPE

im attempting to use G71 cycle to slot out key ways on the shaft work we do here but when i use g28 to send
the machine home after completing the canned cycle im getting an out of shape alarm making it seem the the cycle isnt ending?
as of right now the code runs perfectly except for faulting out in between the 2 tool paths when sent home
i tried running without the G28U0. but even then it faults on me calling out my c position and locking it.
the dimensions on the slot are irrelevant as i intend to turn it into a macro after i get this fault worked out.
also the machine wont accept the other formatting

:example:
G71U.2R.05
G71P10Q20U.03W.003F.01

at all despite it being in the programing manual formatted that way.
this code did run just have to reset and start on 2nd toolpath so the G28 line seems to be the culprit but im not sure how to avoid it

Get the X8.0(retract) out of there and put N200 on the Z-10.188.

Also put G0 on N100 line and G1 on N200 line.

writing it this way seems to have fixed it seems it wanted the data on the same lines as the number
thank you for your help
