Fanuc 3T Post Processor Needed

[Anonymous]

Like the title says. I have a Miyano BNC34T (1985) 

It utilizes a simple Fanuc 3T Control. 

Has a RS232 serial port. I have made the switch from a popular CAD/CAM software wich ryhmes with the latter part 🙂

Will the Generic Fanuc Lathe Post Processor output the correct G-Code?

I have already noticed, it continually sets my G50 at 6,000 even if I have the CSS set at 3,000 or If I disable use CSS it still sets the G50 to 6000 even if my spindle speed is 3,000. Guess if I have CSS disabled it's a mute point.

Anyhow, this is my first post and most definitly not my last.

Any help would be appreciated.

On the post dialog under Properties look for the option maximumSpindleSpeed and set it to 3000.

Another option to might need to experiment with is type (options are A,B,C), for my 210iT I need to set it to B to get the correct format for threads, setting the spindle max speed, etc.

I was reluctant to make the jump to Fusion. So far I have spent 2 days and nothing but headaches. 

When using the Generic Turning Fanuc Post - It doesn't output Canned Cycles such as G71?

Its generating code for each pass?

How is Fusion Running on Macbooks? I have some weird stuff going on. 

[Laurens-3DTechDraw]

No, it will not output canned cycles for turning. So yes you see every pass.

What headaches do you have?

[Anonymous]

I am sure most of the headaches are all on my end.

How reliable has Fusion been running on Macs?

It's my only laptop so I would prefer to use the Mac - So I can easily get my programs onto my different machines.

I have an older Fanuc 3T Controller. I am new to turning and CNC in general. Is there anything I should modify on the Generic Turning Fanuc PP? I see so many different options Such as Type A etc... Not sure what 3T is? Guess I will just need to start sending programs to the controller and doing some dry runs to see what I am getting.

Also how do I add a custom PP file that someone has created and shared with me?

Once I PP it opens up a program called brackets....is that where I communicate VIA RS232 to my Lathe?

Sorry this is all new to me as I was using another CAD/CAM package prior and am trying to give this a shot.

There is a thread here on where to store custom posts: http://forums.autodesk.com/t5/post-processors/where-to-put-cps-files-for-fusion-360/td-p/6093729

Sadly there is no DNC(RS-232) software with the program. There is with Inventor HSM and HSMWorks, but since that(called HSMEdit) doesn't run on MAC they decided to not ship it with the software.

[Anonymous]

Ok,

1.)  So I assume once I generate my G-Code I would need to save that and open into a 3rd party .NC editor so I could transfer Via RS-232

2.) I have Fusion Installed on my Home Computer as well. One thing, every single time I click X or Close Fusion 360 I get (Not Responding) This happens everytime I try to shut it down. Have to enter Task Manager and force quit?

Thanks for the speedy replies. Hoping to get the bugs ironed out and look forward to learning something new!

Additional Quirks

1. Under Cam I have Selcted "dont go home"

2. I also have selected "feed per revolution"

Yet when I PP the Tool Paths, I keep getting a G28 U0 at the end of each operation

I also get a G98 at the top of the Processor?

This is Using the General Turning Fanuc PP Model A (I did try changing to B, and that cleared the G98, But not the G28 U0)

[George-Roberts]

That will be hard coded.. Are you using the generic Fanuc turning post? If so, have you tried changing the type in the properties? The G98 G18 only appears if Type A is selected, see the code below;

  // absolute coordinates and feed per min
  if (properties.type == "A") {
    writeBlock(gFeedModeModal.format(98), gPlaneModal.format(18));
  } else {
    writeBlock(gAbsIncModal.format(90), gFeedModeModal.format(95), gPlaneModal.format(18));
  }

This basically says, if type A is selected, output: G98 G18. If the type is not A, output: G90 G95 G18. Would this be a better fit for your machine?

The following code is what is causing the G28 U0;

  if (insertToolCall || newSpindle || newWorkOffset) {
    // retract to safe plane
    retracted = true;
    writeBlock(gFormat.format(28), "U" + xFormat.format(0)); // retract
    forceXYZ();
  }

This will check if there is a toolchange, new spindle or a new work offset.. If any of that is true, the software forces a retract with G28 U0.

Hope that helps!

What do you mean hard coded?

I am using the Fanuc Turning.cps PP (Generic Turning) I tried some others and it errored out generating the code.

[Anonymous]

So as a new user to Fusion and CNC lathe, Should I keep the G28 U0?

[George-Roberts]

I would keep the G28 U0 if your machine accepts it (I thought all FANUC controlled lathes do). This will move the machine back to its absolute Z0 prior to a tool change.. Last thing you would want is to change tools when your only a couple of mm from the job...
You could probably change it to G53 Z0 if your machine accepts it? Your programming manual should give info on this.

If you are using this as a hobbyist, then keep chipping away and use these forums & tutorials to learn what you need. But if you are running a business and you've just got into CNC, you really should be paying for training.

Have you read through the CNC Handbook? There's a pretty decent page here with links to some handy resources. 

[scottmoyse]

Also for Mac's, or any Fusion user, I recommend buying the G-Code editor from cnccookbook.com. Also a great resource for you to get into if you aren't already aware of it.

[Anonymous]

I am still trying to figure out why I cant shut down fusion on my PC?

Everytime I get (Not Responding)

It runs better on my macbook but the menus are different then the PC version and most help and tutorials revolve around PC based.

Yes I have a day job, and my CNC machines are in my home Hobby - Shop which I am tring to desing and make products - So Its sort of a business, just not the one that pays my bills 🙂

Some intersting things happened today, I will be adding a Fanuc 21iT Control to my Stable!!

[scottmoyse]

Maybe look at doing a Clean Uninstall of Fusion, then reinstalling it to see if it starts behaving better on your PC. What are the specs & operating system of your PC?

Those HD 4000's are probably a bit low spec'd for Fusion. Do they have the latest drivers?

[Anonymous]

Most likely no. I tried to update the PC version earler and encountered an error.

I was needing a new comp anyways was thinking about getting a much better PC based Laptop with 16g Ram SSHD and a Gaming Geforce 960 Card

Ill try to update my graphics card in the meantime

[Anonymous]

Today I noticed the Post Processor both A and B use a G83 for a Deep Drilling Peck Cycle.

My Machine wont support G83 and needs a G74 Cycle. I don't think my machine can use 83 Via Macro as well (85 Miyano BNCT)

Can I modify the PP to use G74 for a full retract peck drill cycle?
