Parameter 3109 Display W and G

Tags : Change Fanuc Parameters Fanuc Parameters

People who know me know just how boring I am. Today I’m going to confirm this by getting very excited about this parameter.

Parameter 3109 bit 1 (#1) DWT will make the display of wear offsets loose that confusing W and G.

Stay here I’ll explain more.

Messing With Parameters Can Be Fatal!!!!!

Parameter 3109, to change this parameters first you need to go to the setting screen in MDI.

Put a 1 in the parameter write box.

Today we are going to change the parameter that stops the offset page displaying G and W.

Bit 1 (#1) DWT make this a 1 to stop this being displayed.

So when you change this parameter you won’t see a W beside the offset number in the wear screen. You also won’t see the G beside the tool number in the geometry screen.

I know for a fact when training people that this really confuses them. Especially the the G on the geometry screen.

This is it before with the W

Parameter 3109

This is it with the parameter change good old fashioned numbers.

Parameter 3109

As in the book

Parameter 3109

Bits n Bobs

When counting the bits in parameters you count from right to left so the first one on the right is bit 0 or sometimes known as #0

Other Parameters Of Interest

1300 Stops over travel alarm

1401 Cutting Feed-Rate 0% stops movement of machine

3101 Clear Screen

3102 Unlock Programs

3203 Clear MDI Screen

3204 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3291 Wear Offset requires Key to Adjust

3401 Calculator Type Decimal Point or Integer

3402 G Codes that are Active When The machine is Turned On

5003 Retain Geometry when you Press Reset

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059 Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

Oh just one other thing before you go off and cripple your machine forever.

Do yourself a favour take a picture of the screen before you change a parameter. If you ain’t got a camera then you must have a piece of paper.

Even better back everything up.

Thanks

How To Format a Data Card on a Fanuc Control

Tags : Fanuc Fanuc Data Card Format Data Card

Category : Fanuc Fanuc Mill Fanuc Parameters Fanuc Turn

Format a Data Card on a Fanuc Control yes that’s what were going to do. Now first of all I have a confession to make.

People often say to me how nice it is of me to write all these articles helping people with the shit they can’t do. Well sorry it’s not true actually I’m just a selfish bastard just like all the rest of you.

My only reason is that I have and always have had the memory of a goldfish. If you have ever had a goldfish and tried to train it (which I once did). I read books on it like “How to Train Your Goldfish in 3 Easy Steps”, for which I got a refund.

Anyway I digress. The reason you can’t train them is, not least of all because you can’t keep them out of the water too long, but they don’t remember a word you say. Fuck all, Jack shit.

So the minute they learn a nice trick they immediately forget it. It doesn’t bother them because they just forget that it bothered them.

Sorry no more about Goldfish.

Anyway its really easy to Format a Data Card on a Fanuc Control. You just hold in these two babies while switching it on.

Oh and make sure you have data card selected in your parameters.

This is me doing it. Yes that’s my gnarled up old hand.

Overtravel Axis Fanuc Parameter 1300

Category : Fanuc Parameters

Messing With Parameters Can Be Fatal!!!!!

Over-travel alarm, make this a thing of the past with this parameter

You first need to go to the setting screen in MDI.and put a 1 in the parameter write box.

Today we are going to change the parameter that stops the machine generating an alarm when it gets to the end of travel.

End Of Travel Alarm Fanuc Parameter

Now I need to start by apologising to all the lovely people at Fanuc. All the years I have moaned and moaned about the fact that when you get to the end of the machine stroke on a Fanuc control you get a stupid alarm.

Actually I have been totally wrong and I offer my sincere apologies to all who have been hurt by my nasty comments about this.

If you set parameter 1300 BIT 1 (NAL) to a 1 then you do not get an alarm when you travel to the end of the machine stroke.

This should make it work. If it doesn’t then maybe you should call the Samaritans.

Bits n Bobs

When counting the bits in parameters you count from right to left so the first one on the right is bit 0 or sometimes known as #0

Other Parameters You may Want to Change

3203 Clear MDI Screen

3202 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3402 G Codes that are Active When The machine is Turned On

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059 Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

5003 Retain Geometry when you Press Reset

3291 Wear Offset requires Key to Adjust

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

This guy has more CNC Manuals than you can shake a stick at.

Oh just one other thing before you go off and cripple your machine forever.

Do yourself a favour take a picture of the screen before you change a parameter. If you aint got a camera then you must have a piece of paper.

Even better back everything up.

Or take a screen shot.

Cutting Feed-Rate 0% No Movement

When you set you feed-rate override to 0% the machine will not move. Some operators like to use this when proving out a program

All you need to do is make Bit 4 of parameter 1401 into a 1 and the machine will not move even in rapid.

Fanuc Parameters 3101 Clear Buffer

Fanuc Parameters, does it really annoy you when you swap screens on your Fanuc control and you loose whatever you just typed in?

Well it’s OK, no more sleepless nights. It doesn’t have to be that way thanks to Parameter 3101

Bits n Bobs

When counting the bits in parameters you count from right to left so the first one on the right is bit 0 or sometimes known as #0

Messing With Fanuc Parameters Can Be Fatal!!!!!

To change a Fanuc Parameter you need to go to the setting screen in MDI. Now put a 1 in the parameter write box.

Now We Can Get This Party Started

This is how Parameter 3101 looks in the Fanuc Manual

Fanuc Parameters

It’s Fanuc Parameters 3101 bit 1

When this is a zero. If you change screens your code is lost.

Now here’s one I prepared before the show

This is how it works when you change the Fanuc Parameters 3101 to 1

The Dreaded Options Fanuc Parameters

I once bought a new car and naively thought it would be just like the one I saw advertised on the telly.

On some cars everything is a fuckin option. Well unfortunately it can be a bit like that with CNC controls.

It’s not all doom and gloom, a lot of the things you can’t get the control to do are just settings and parameters.

Keep reading my articles and you’ll find out what they are.

All this boring shit really does have a point to it.

If you have a lot of similar controls in your company it’s a good idea to try n set them all up the same way.

Don’t get me started on Haas.

OK You Started It

In my opinion by far the greatest thing about a Haas control is the program restart.

Guess what: most people have it turned off. I would liken it to switching off your central heating in the winter and making a fire with some sticks in the middle of the room.
