[bigjohn]

Which one is Post line number 578?

[pinlec]

tap_out = n_tap_thds

[Rob_Bish]

yours only has:

 

ptap #Canned Tap Cycle

 

 

Not what i said. you have put it in the wrong place should look like this:

 

ptap #Canned Tap Cycle

pdrlcommonb

 

tap_out = n_tap_thds

pcan1, pbld, , *sgdrill, sgabsinc, *sgdrlref, *xout, *yout, prdrlout, *speed,

tap_out, strcantext, e

pcom_movea

[Rob_Bish]

You also have this further down in your post:

 

ptap #Canned Tap Cycle

> pdrlcommonb

> result = newfs(17, feed) # Set for tapping Feedrate format

> pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

> prdrlout, *feed, strcantext, e

[pinlec]

prdrlout #R drill position

if cuttype = one, refht_a = refht + (rotdia / two))

else, refht_a = refht

refht_i = refht - initht

if cuttype = three, refht_a = w

if absinc = zero, refht_a, !refht_i

else, refht_i, !refht_a

 

ptap #Canned Tap Cycle

 

pbrlcommonb

 

tap_out = n_tap_thds

pcan1, pbld, , *sgdrill, sgabsinc, *sgdrlref, *xout, *yout, prdrlout, *speed,

tap_out, strcantext, e

pcom_movea

 

pdrill #Canned Drill Cycle

pdrlcommonb

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

prdrlout, dwell, *feed, strcantext, e

pcom_movea

 

 

after i changed to,the error command show
