Hi, I got Miyano BND 51s5 with Fanuc 21i-T controler
been keen to do ridgid tapping
I performed the command

G97 s1000 M3
G84 z-10 F2.
G80
G0 x100.0 z100.0

and wha happend is acually the tool went right in M3 and right out with M4
but what was missing is that when the tool reached to z-10 the sppindle took a long time to stop thus breaking the tool and didnt syncronize the feed with the spindle speed usually with proper ridgid tapping it should slow down when it starts reaching the z-10 then turn to M4 but what happend is the tool reached to z-10 first then the spinde stoped after reaching to z-10 ...is that paramerts problem? or its simple missing hardware piece on board?

i tried to put M39 (the 2200 parameter is set to 39, so I tried using
M39 s1000
g84 z-10.
etc..
but the spindle refuses to turn on M39 command..
anyone can help?
