Sequence No's for lathe G71 G70. How to change?

[bigjohn]

G'day all.

Is there a way to change the output of line No's in can cycles G71, G70 starting from 100 with increments of 2? At the moment I have:

 

code:

Or something similar. Can someone help me get it right? I have tried many different ways but obviously the wrong ways, there is no change. I don't know what I'm doing any more. N2 in this example is the same as tool change line N2 for tool 2.

 

Thank you for any help.

Out of MPLFAN did you look here???

 

code:

---

prcc_call_end$   #Rough canned cycle end

 

# Restore cc_1013 to the value it held prior to the rough # 1/17/03

# groove canned cycle. cc_1013 was changed in ptoolend. # 1/17/03

if tool_op$ = 208 | tool_op$ = 62, cc_1013$ = sav_cc_1013 # 1/17/03

 

if tool_op$ <> 208,

[

omitseq$ = sav_omitsq

#Close the ext file

result = fclose (sbufname3$)

#Open the ext file as a buffer

#Use the size to determine the start and end sequence

subout$ = sav_subout

size3 = rbuf(three, zero)

if omitseq$ = one,

[

ng70s = n$

ng70e = n$ + seqinc$

]

else,

[

if old_new_sw = zero, ng70s = n$ + seqinc$

else, ng70s = n$ + (seqinc$ * two)

ng70e = ng70s + (seqinc$ * (size3 - one))

]

pwrite_g70

]

Thank you Ron for your answer. I did find that section in the post, and it is the same as your code, however I don't know how to edit it to output seq No's starting from 100 with increments of 2.

 

Forgive my ignorance and thank you for your help.

Lathe X2-MR2 using the MPLFAN.PST

 

In the Control Definition on the NC Output page...

In the Sequence numbers groupbox ->

 

Output sequence numbers is unchecked

Start sequence number = 100

Increment sequence number = 2

and

In the MPLFAN.PST ->

omitseq$ : -1 #CD_VAR Omit sequence numbers? (use -1 to enable sequence for LCC)

 

Gives me this output ->

John we are learning and no need to apologize.

 

Roger thank you for that better method to handle this.

[bigjohn]

Thanks Roger and Ron. You are very kind and helpful.

I am modifying a Generic Fanuc 2X Lathe.PST for a MORI LATHE - FANUC 15T CONTROL. I must have disabled something somewhere in the post that doesn't let me get those No's right. I tried Roger's rip with an unmodefied Mplfan.PST and a Fanuc 2X Lathe.PST that have not been edited and they worked very well. Now, my next job is to find where I messed up. Find the error or start from scratch.

 

Thanks again. The tip worked whith those 2 posts.

I also need some help, When I post I get the sequence numbers but for every G70 Cycle the output is the sequenece numbers from the first Rough pass; for evey single finish.
