Tricky question?? I have been trying to tweek a post processor to post codes for a a2100 control on a tree mill. the machine likes the drilling cycles to all use g83 with a j1 for no peck, a j2 for peck full out w/ k value, and a j3 for peck full out w/ k value and decrease peck by i value all canned cycles use w.? i.e w.1 for the retract point and it must be put in each block. so an example of ideal program is right hear. The main problem is the $ symbol and space between W.1 I have done a ton of editting so far to get to this point. It started as a purely fanuc flavored post slightly tweeked for a fadal with 32 'E' offsets. there now 'H' offsets. i removed all tool offsets and have got the drilling cycles this far. im just an amature programmer with 3 years of mastercam and gibbs under my belt 4 years of writing g code by hand as well. This is celarly the logical step to undertake. Im sure we all could trade knowledge on this thread, it is an interesting question in my opinion. Any help would be greatly apprecieated.
