lathe thread feed

[clayallen]

where in the post do I edit to get lathe thread feed to be 4 places, instead of 2pl?

 

N970 G76 X.3937 Z-.1 P0219 Q0100 R0. F.04 <<< supposed to be 4pl. (F.0357)

#Default english/metric feed format statements
fs2 17  0.2 0.1     #Decimal, absolute, 2/1 place <- Right here I think ( change the 0.2 to 0.1 to 0.4 0.3)
fs2 18  0.4 0.3     #Decimal, absolute, 4/3 place
fs2 19  0.6 0.5     #Decimal, absolute, 5/4 place
fs2 20  1 0 1 0n    #Integer, forced output

 

I may be wrong so make sure you can change back whatever you mess up

Actually, i think the g76 thread is supposed to use fs 19, or fs 18. (See below) But for some reason my post ignores pfr_l, and is using fs 17 instead. (which is 2/1 place) If I change fs 17 to 4/3 place it will affect all the other feed statements. 

 

(format for lathe thread)

pfr_l           #Format feedrate for lathe

      if opcode$ = 104,

        [

        #Format feedrate for lathe thread

        result = nwadrs(strf, feed)

        result = newfs (19, feed)

        ]

      else,

        [

        result = nwadrs(strf, feed)

        result = newfs (18, feed)

        ]

 

Curiously the change to the fs 17, 0.4 0.3 worked, but didn't affect the other feed rates. Makes no sense.
