Did you read the first post in this sub-forum???

Asking for a Post Processor... -------------------------------------------------------------------------------- Ask this question as your first message and you might not get the response you expected. Developing custom posts is long, difficult work, and most people that have built thier own or paid for them are probably not going to be willing to give it away for free. Mastercam comes with posts for most machines that are good starting points right out of the box. Often times customizations are required or desired. Your first course of action should be to search the CD for a post for your machine. From there, you might ask for help to change specific items in your post. Most post developers are very willing to share code snipits or give advice on editing posts to attain desired results. If you can't find the post you want, try your dealer next. They should be able to help you locate one. __________________ Matt CNCzone Administrator San Diego, Ca

thanks for your reply mastercamguru, and yes configuring a post program is very time consumming, but the end result is very rewarding. i spent the last two evenings until 2:00am getting this post right and i finally got it. You replied "Ask this question as your first message and you might not get the response you expected" your right it is a long process and most people probally wouldn't give there custom posts away, i did not realise they were of value. This post was for my own personal use at home and didn't think it would be a big deal for one machinist to help another machinist out. then i thought about it, if a company paid for a custom post your probally not just going to forward it to anybody. thanks

[KEN_QUICK]

I had no idea that post processor files were such a valuable item.

[mastercamguru]

KEN:
I don't mean to scare you away from the forum That is not my goal.

I paid $1500.00 for a high end post a few years ago, and out of lack of wanting to "pay up" again, I learned to read and edit MP language . (Post Processor Code).

The guys that write them for Mastercam have Masters' Degrees, and for good reason.


I will help you with any modifications you need to do, but I will not provide custom posts for anyone.

I made the mistake of doing this already, and will follow through with my offer because I am a man of his word.

If you need any help customizing your post I am more than happy to help.

Just ask for it.......Just don't ask for a Free post".....I want a teaching/mentor relationship, not a one-way relationship.

If you are willing to learn, I am willing to teach.

MASTERGURU:

Thanks for your offer and the insight as to what i was asking for. I had no idea that a post file could cost that much. i have been programming cnc machining centers for 24 years, 20 of those years were without software and was very time consuming. But i have never wrote a post program or even seen one until the beginning of last week. i am happy to say that i have edited 3 posts over the weekend(not that i need three, only one)with great success, my programs are posting the way i want them to post.

thanks ken

Hi Ken, I'm struggling to get Mastercam V9 post processors sorted for a Bridgeport series 2 cnc on Boss 6.2 and for an Agiecut 100 wire machine.

The problem I have is that the guy who does som cad-camming with me is a whizz on Mastercam but we can't post to the machine even though he has a bridgeport post processor of some type.

I went on to buy BobCad-cam software with all the Milling and wire pro programs which comes with post processors for my machines and even incorporates Predator, the DNC software.

The only problem is the cad-cam guy doesn't like the software so i'm forced back to trying to produce good post proceesor files from the mastercam so I can send.

Looks like I lost all my money on the BobCad-Cam software.....nightmare!

I've been using a bit of shareware software called Terra Term to send 10 lines of hand written program which where copies of sample programs of machine code to the Bridgeport but I'm really struggling.

Can you please assist me!

Any help would be massively appreciated.4

Thanks

Darren

Mastercamguru's $1500 post was probably for a high end machine with lots of High Speed Machining features. Not all posts are $1500. I write posts for a living. Some are as little as $175. Some are $3500 (5X posts). For most people, if it's a 3X fanuc compatible control and they take the time to include the correct information about their machine, it can usually be done for about $250 +/- $100. So you have to ask yourself, do you want to spend 12 hours writing a post? or would you rather pay someone $300 to get it done ASAP?

You said something about "posts being so valued". It's not the post that has the value, it's the persons time and knowledge. What's your time worth.

Mastercamguru just helped someone write a post for a Fanuc 7 (I think it was). I commend him for his work. I saw the output code in these messages. He did a good job. I knew when I saw the request, it wouldn't be impossible, but it wouldn't be a quick post modification. I'm sure it was an excellent learning experience. Then you have to watch out for the... "Oh can you fix this one more thing..." . :-)

Daz1973 --- Can you post some sample code that works?

Maybe I can get you cutting some chips.

I'm sure I can find something close for the mill ... not sure about the wire edm.

[mastercamguru]

Mike --- That $1500.00 included a guru for the day to make sure all was well .

That guru's name is Steven Beihl .. S4A ... nice guy.

I still bump into him once in a while on the Emastercam developer's forum.

[charger19690]

I have edited Mastercam posts from V9 now thru X3 for Fanuc/Haas posts.

When I started out, first, make a copy of the post you want to modify and use that as your custom. NEVER OVERWRITE your original post.

The way I started out was just looking for the code you want, find out the variable and start moving from there.

With the MasterCam X platform, you can change alot of things through the front side of the control with the Control Definition Manger and the Machine Definition Manager. That has made alot of things better.

The layout of the code is where things get a little more complicated, but doable.

I have had to make a post for a machine that has a Tool Change Location move prior to tool change, so the post will spit that code out everytime there is a toolchange.

The last shop I worked at wanted a "M01" after the toolchange, and that was fairly easy, but we did not use "Sequence Numbers" throughout the program, but it was how we started off a new toolpath, example, T1M6 had an N1 before it, T2M6 had an N2, etc., this took some doing, but possible.

I would just say read through the code and figure out the variables. It's doable, but time consuming.

We asked our dealer about a post for our Nakamura Tome TW-20. They said they would have to buy that post. Cost to us $2600. We didn't get one.

I program this lathe and prefer manual programming, so it isn't a big deal for me. Other lathe programmer only uses MasterCam. I am older than he is, tho I may not be able to retire before he does.

Regardless sometime down the road this lathe may need a post processor. I don't expect to live forever. LOL. From what little I've seen, finding a replacement for me that understands g-code programming won't be all that easy. Everyone likes to use software programs. Guess I will be spending some time trying to develop a post for the TW-20.

I'm sure I will be asking for help sometime down the road.
