Is there that much of a difference from an mpmaster that was converted using the updatepost c-hook? Any difference?

Yes. You have the "Peace of mind" that Inhouse has proof-read and tested it.

That's too funny!!!

Actually gcode teh beta tester had trouble

updating a couple of X3 mpmasters,

He sent them in to Mastercam QC and In House.

They discovered an improperly declared

vairable that was causing X4 to error out.

CNC Software edited the update chook to fix the problem so that updating mpmaster to X4 would be trouble free.

Why is the Mpmaster format the way it is?

This is what is posted, I deleted the

un-nessesary stuff

AND ON TO THE NEXT TOOL........

 

The Mpmaster has redundant G codes and looks sloppy.

The modified format listed above I have used for years on Haas, Fanuc, Yasnac, Mazak EIA mode controls with very little mods between machines.

The Gcodes are in order and each tool is a self contained tool, safe to run from any position or fixture set up.

 

Just my thoughts.

If you're looking that close at code then you have too much time on your hands. I RARELY ever look at code anymore. It serves almost no purpose. I figure if I did my job programming, the code should be good. I've seen sompanies print out their programs... talk about killing a forest... my goodness, printing out 10,000 lines of code... for what? All you ever need to look at is the start of the tool, operation to operation transitions on null tool changes, and end of tool. That's it. If you're looking at more then that... you're wasting time.

And this matters because????

 

MPMaster is a generic post MEANT for modification by the end user/post writer. It is the post that many of us START with, but like you we have certain tastes. Personally I could care less about redundant code. If the machine does not care, why should I?

It as you stated a personal preference, but I have talked to many guys who are not programmers, but set up people. They will do simple modifications to programs, like combine operations with two vises ect. They do not like things out of order, because they do not fully understand all of the aspects of G-code. I like to keep every thing eazy and straight forward for them. I guess I am a little to finicky, but I teach this stuff too, and I find that I can explain to my students easier when the format has fewer duplicate G-codes, and follows a simple step by step process of starting and ending a tool. As Machinist, why shouldn't we strive for a simpler more universal approach to CNC machining. If a shop follows a fairly consistent format from machine to machine it is much easier for employees to migrate to different machine centers with out the panic of "hey this program does not look like the other machines"

Again I guess it is a personal thing, but it does look cleaner.

I am agree with JESO Mpmaster is absolut ridicuious!!!

Then don't use it!

[Rob @ Target Machine]

Mpmaster is a very powerful starting point for a custom post.

 

Predator & Metacut tool tables, HSM type output, multiple coolant code support, the list goes on and on.

 

If you don't like how the code looks, edit the post. If you don't know how, learn the MP language.

 

This is code from my Mpmaster post.

 

As posted ... no edits.

Kind of part Mpmaster part Mpsubrep style posting.

 

EDIT: Once you get to understand MP language it will become clear that Mpmaster is a very bad a$$ post and it's free.

That's pretty clean code IMHO.

No kidding... MPMaster smokes MPFan everyday that ends with "Y".

 

No Offense to the CNC guys but MPMaster is just a way better post. Even with the occasional update bug.

Yeah, but your codes are not in numerical order so it's rubbish

[DavidB]

In-house give out a FREE post that rocks and your still not happy.

 

Even I can edit it to give me excatly what I'd like to see and I'm NO post guru at all.

[Rob @ Target Machine]

CNC Apps Guy - You're right, G54 was missing. I accidently set mi1$ to zero turning off WCS numbering.

 

Thanks for pointing that out for me.

Better?

[Grumpy Guy]

I agree that the MPMaster is a good post; it is the "Gold Standard" we should all start with. I never said it would not work, it works fine. I just had a small complaint about the program formatting, and feel that the post could be rearranged just a little to make cleaner more professional code. I am anal I know, but working with machinist on the shop floor, and running programs formatted with the stock MPMaster I realize it could be rearranged just a little, then the MPMaster could be shipped and used virtually as is.

Working and teaching this stuff has revealed to me how many shops do things so differently. One of my biggest frustrations is many CNC Machinist run the machines but have no real clue what the program is really doing. I can ask three guys to explain to me what G43 does and how it works with the WCO system and I will get three answers. I still have guys tell me they use different height offset registers when running a program with multiple WCO registers being used. One of my students told me how the shop he worked at can never use positive offsets because there machines will crash……………

When I looked at one of the program formats it contained “G49Z0” as a tool retract line. I asked why that line was there, he said it was how the machine would retract the tool to the machine home position (WRONG), but could not tell me why it would crash…….. Our industry needs to work smarter, CAD/CAM does much of this for us, and we ALL benefit from it, but knowledge still needs to be passed down to the shop floor, to the guys who are “making the chips”. I understand format is just a silly thing but streamlining simplifying, standardizing things will do a lot for the shop floor machinist.

Me as a programmer I do not care what the program looks like either, I push cycle start and let it rip, but as a Programmer, and teacher I understand the importance of the “Guy on the floor” and like to help them understand what they are doing, and not just go thru the motions of every day life making chips.

Whenever I've taught guys on the shop floor, I always told them don't get hung up on "housekeeping" issues. I say that because eventually in their pursuit of the cleanest code on the planet, they are going to forget/miss something and get burned!

"I say that because eventually in their pursuit of the cleanest code on the planet, they are going to forget/miss something and get burned!"

 

Amen Brotha,

why should i care if a G1 is being called more than once, the machines don't care they just cuts.

i worry more about the start of file,tool changes,end of file features. if the post is good and the code is bad then so was my programming!

[Guest CNC Apps Guy 1]

I know if I get too hung up on "how it looks", I'm never satisfied. I keep tweeking and screwing around with something that will not get the part done any faster or any better for that matter so what's the point. If it runs, RUN IT!
