If you're testing your program in single block, the block containing the synchronize code (M39 in your case) does not start the spindle. In all cases of rigid tapping I've seen, the spindle starts when the G84 block is executed and stops upon its return to the R level after completing the tapping operation on the current hole.

Are you confusing bit 0 and bit 7 of #5200, or are you just making the observation that bit 7 is set to 1.

hi, first i tried without single block still the spindle wont turn on M39 command
and as far as i know Bit 0 is on the far right like this?

#7 #6 #5 #4 #3 #2 #1 #0
so in this case bit 7 on mahcine default is set to 1
i can change that to 0 ofcourse but what would that do?
all i know if i put that to zero then i have to use M39 if i leave it to 1 then i dont have to use M39 s1000 is that correct?

in anycase regardless if that is set to 1 or 0 spindle wont more on M39 command..

Yes you're reading it correctly, bit 0 is the right most bit in the byte. However, its bit 0 of #5200, not bit 7, that determines if an M code is used for rigid tapping, and should be set to 0 if the M code defined in #5210 is to be used.
