Pro/nc or UG NX post processor

[prcdslnc13]

Has anyone had any luck using these software's for EMC2? I have access to both of them at work and would like to learn to use them better by working with them on my cnc router that I built. Any help would be appreciated!!!

I have used pro NC and EMC2, but not together, because i dont have the EMC2 post processor. Would you send it to me? I really need it and would be most gratefull. Once I have it maybe I could help you.

Thats what I was looking for before but never found one. Sorry

How complex is your Router? As long as the G-code is only G0, G1 G2, G3 codes, it ought to just work anyway.
Have you tried something vaguely generic? RS274 is meant to be a "Standard" after all.

emc is basically fanuc or rs274 code with some minor additions to provide more functions.
.
unigraphics nx comes with a basic 3 axis mill post processor and by using postbuilder you can customize it. some items can be modal or called out once like G90 (absolute mode) but it can be easier to read if G00, G01, G02, G03, X,Y,Z, I,J, F are non modal and called out on each line.
.
for example calling for a tool changer to change tool if you are doing it manually, whether you want to use absolute or incremental coordinates and how you handle arcs if you use I and J then often I and J is incremental but X Y Z is absolute coordinates.
.
you have to check all G code and M code. for example some machines use G20 for inch mode others use G70. refer to EMC manual
.
number one rule is make a list of all items you are doing when making a post processor. it is easy to try to make 100 failures because you can easily forget different steps on each try. once you make a list of all items done to make a post processor you can easily recreate it by following the list (procedure). this can be the difference in making a custom post processor in 10 minutes or 10 days.
