Lathe / mill ?
What axes does it have ?
We can show you what changes are required , or point you to a post to start off with to modify.
We do need initial info to help you out.
***** 1st COPY THE POST ******
,e is on the end of output lines
# denotes a comment on trailing data ie n, *t, e #tool preselect
* forces the post to output that string data to the ncfile
"" anything in quotes is directly output to ncfile
For header modifications, search for "pheader" or "psof"
this is usually the 1st thing processed by most posts
for toolchange stuff, is usually after the header, look for ltlchg, ltlchg0 or ptlchg, ptlchg0 for lathe or mill
sof = start of file ( start of file, can contain the header info )
eof = end of file ( ending the ncfile )
ptlchg0 = what happens between operations that use the same tool
pl_retract or pretract = proceedure for retracting from part and then toolchange
Remember, do a small number of mods, then check the output. It can be difficult to find where you missed placing a comma or something similar.
Practice on the header component 1st, this should not affect the actual toolpathing codes.
BTW welcome to the forum
