thread lead not posting correct K556 is what i am getting for lead but it needs to be k5560

You will need to edit the post processor.

 

Find what variable is used for lead or pitch or feed rate.

 

You should be able to find it in the pthrg32_3$ #G32 threading third post block if using a mplfan or mplmaster based post.

 

 

pthrg32_3$ #G32 threading third

copy_x = vequ(x$)

pcom_moveb

pcan1, pbld, n$, psgfeed, *sthdgcode, pxout, pyout, pzout, pcout, pffr,

strcantext, e$

pcom_movea

prv_gcode$ = m_one

 

 

In this example the pffr post block is the one used

 

 

pffr #Output feedrate, force

if ipr_actv$ = zero, pfr_m

else, pfr_l #This makes the call to pfr_l post block to format the feed output

*feed

 

pfr_l #Format feedrate for lathe

if opcode$ = 104,

[

#Format feedrate for lathe thread

result = nwadrs(stre, feed) #Most likely your post is set to strk to output a "K" for the lead

result = newfs (19, feed) #This formats the feed rate using the fs2 table found near the top of the post

#In mplfan.pst this format statment is fs2 19 0.5 0.4 #Decimal, absolute, 5/4 place this indicates 5 decimal for inch and 4 for metric

#I see from your code that you require no decimals so you would want to force trailing zero's something like

# fs2 19 0.5 0.4t #Decimal, absolute, 5/4 place adding the "t" to the format statment will force trailing zero's

 

 

]

else,

[

result = nwadrs(strf, feed)

result = newfs (18, feed)

]

 

 

Now if your post is not based on mplfan or mplmaster things will be diffrent however the principal is the same.

thanks for the info , yea mine is diffrent

ptpr32_2 #Taper code output for G32

thdrdlt0 = ( thdxdlt * thdlead$ ) / thdzdlt

*thdrdlt0

 

ptpr32 #Taper code output for G32

if thdxdlt <> 0, ptpr32_2

 

pg32_1 #G32 threading

thdlead0 = thdlead$

zout = z$

xout = x$ * dia_mult

n$, *zout, !z$, e$

n$, *xout, !x$, e$

n$, "G33", *thdz2$, ptpr32, *thdlead0,"0", e$

xout = thdxr * dia_mult +.1 <-------------------i added this to get clearance

n$, "G00", *xout, e$

 

here is the k it think

fmt K 11 thdlead0 #Thread lead

 

 

# --------------------------------------------------------------------------

# FORMAT STATEMENTS - n=nonmodal, l=leading, t=trailing, i=inc, d=delta

# --------------------------------------------------------------------------

fs 1 0.4 #Decimal, absolute, 4 place, default for initialize (

fs 2 0 4t #Decimal, absolute, 4 place

fs 3 0.4d #Decimal, delta

fs 4 1 0 #Integer, not leading

fs 5 2 0l #Integer, two leading

fs 6 3 0l #Integer, three leading

fs 7 1 0l #Integer, four leading

fs 8 0 4t #No decimal, absolute, four trailing

fs 9 0 2t #Decimal, absolute, 2 place

fs 10 0 4t #Decimal, absolute, 4 place

fs 11 0 4t #Decimal, absolute, 5 place

fs 12 0 2t #No decimal, absolute, four trailing

fs 13 0 3t #No decimal, absolute, three trailing
