Posts for each machine are much easier to maintain and customize. Keep It Simple and your life becomes easier.

Take one post and copy it for another if the machines  are very similar, then tweak to that machines needs to deliver a NC tape that is efficient.

By using multiple posts, you can include custom PPRINT statements to help the machinist and others who may look at the printout.

Hi @asifcad,

Thank you for your question. 

Your post appears well documented but has not yet received any response. I am replying to raise awareness. Hopefully, another community member will be able to help.

Also, feel free to add any additional information you think might be relevant. It sometimes helps to have screenshots to better understand what you are trying to do.

in Gpost  Option file generator   in 'Advanced tab' Fil editor....

 

cimfil/on,loadtl
rslt=postf(2,1,2707,1)
rslt=postf(13)
rslt=postf(2,1,2707,0)
TNUMB=POSTF(7,4)
TNUM=TEXT/CONVF,TNUMB,8,4,0,1,4
insert/'G43.3H',TNUM,'Z210.00','$'
cimfil/off

 

I get this:

 

T09M06
G43.3H9Z210.00
S75M03
G0X-.27383Y.303

.......................

The Z210.000 is fixed/hard coded. Can have it use your retract plane.

    Hello, Peter Mueller. Many thanks for the reply...(The Z210.000 is fixed/hard-coded. Can you use your retract plane) Is it possible that Z value is also derived from NC Sequence Retract or the Clearance Plane?also how post processor know which sequence 3 and which is 4-axis or 5-axis.

    I'll look into this one when I have time. 

    I use multiple posts for 3.4 and 5axis. Less complicated
