Help with 8025M Tool Change Subroutine

Hey Everyone,
I could use some help with getting my tool change subroutine to work on my 8025M router. The tool changer is a Non-Random 6 tool changer (basically just X/Y tool positions {ISO30 tool clips} mounted along the long side of a 4'x8' table). Here is a rough diagram:

....._T1_T2_T3_T4_T5_T6_
__/____________________\__
|......................................| ^
|......................................| |
|......................................| Y=4'
|......................................| |
|o_______________________| v
<----------- X=8' --------->

After a machine reference (Home):
The absolute coordinates of the table origin are at (X6.365,Y0.135,Z-5.75).
The absolute coordinates of T1 are @ (X39.643,Y59.990,Z-4.702).
The TC subr references the position of T2-T6 to the positon of T1.
The table soft limits (absolute referenced from machine ref zero) are:
XPos=111.0, XNeg= -1.0
YPos=61.5, YNeg=-0.5
ZPos=1.0, ZNeg=-5.75

There are two programs that I am trying to use (attached at the bottom of this post). The first program (%43210) is a short program that simply calls for a tool change. The second is the tool change subroutine (%99998). The TC subr has a lot of comments included here, but I have stripped them out on the version that I have loaded on the machine.

PROBLEM

When I try to just run the %99998 in single block mode, I get the following:

Error 016 : N _ _ Doesn't Exist
N0310 G26N3000.3030

The Error Code Book says: Error 016 - The called subroutine or block does not exist or the block searched by means of a special function F17 does not exist.

As I scroll thru the lines of code on the machine, the blocks N3000 thru N3030 are definitely in there, but?!?!?!

Any help or insight would be greatly appreciated.

Have you actually ran that code?

I run an 8025, and have an 8025M mill I'm getting online, but I've never seen any Fagor code programs written like that, so no help here. Never ran single block mode either.

I would be very interested in seeing your tool holders on the table. I would like to do the same for my mill, and have thought of a setup like that. Any pictures?

How far north are you?

Another possible thing is your block numbers with "N00". Maybe that's what it means by N_ _.

I never run zeros before the line number.

Example:

N10
N20
N30

Not-

N0010
N0020
N0030

Now No Error, But Stuck "In Execution"

So, in an effort to try to troubleshoot this, I forced the machine to think that there was a different tool in the spindle.

Prior to this, the machine last thought (correctly) that T3 was in the spindle, and when I ran the TC program it errored as described above.

Now, I forced the machine to think that T4 was in the spindle (changed T03 P00 & T04 P04 to new T03 P03 & T04 P00). In addition, checked to make sure that the tool table showed T00 P04.

When I ran the TC program this time, the machine got stuck "In Execution" somewhere in the M06 routine. I let it sit for 5-6 minutes waiting to see if it would do something (which it did not). It seems that the machine is waiting for something, or the program is stuck in an infinite loop of some kind.

I also have noticed that after interrupting the program, the tool parameters show T06 P99. This seems important since the tool change program is trying to change to T6.

The book says that P99 indicates one of two things:
The tool is in the tool changer, or;
M06 has not been executed yet.

Since I don't actually have a tool changer (only spindle and pockets) - it would seem that the machine is waiting for something to actually finish executing the M06.

Any ideas?

Back to troubleshooting.

Hi Pat

Hey Pat,
Thanks for the replies.
The Error 16 has been overtaken by a new type of problem - see my previous post.

I'm just south of the Redding, CA area.

I don't have real close up pix of the tool holders, but you can see the basic set up on one of my threads here:
w w w . c n c z o n e . c o m/forums/commercial_cnc_wood_routers/129173-anyone_have_any_motionmaster_documentation.html
You'll have to take out the spaces.

If you are able to fit some of these on your mill somewhere, AND I get this code working, I'd be happy to share it with you.

I can also send you some close up pix if you'd like.
R/Todd

I live in the next county west of you. I'm down there often.

Question:

Have you ever operated this machine before? Do you have a program that has worked in the past?

I don't see how any T codes or P codes the way you are using them will work.

Stuck "In Execution" - DUUHHOO!!! F=0 Dipstick.

OK, so when you have the Feedrate Override knob set to 0 (Zero) - you get "In Execution" forever when you are trying to step through your program (or pretty much anything, really)

Duuhhhooo!!!!

That also means that the Error 16 is back. Yay!

Back to the drawing board.
R/Todd

Feed rate knob has to be turned all the way up.,

Is this a new machine for you?

No, Nubie to the F8025M

Hey Pat,
Yes, I'm a nubie to the F8025M (see my previous post).

The code that I posted is the (almost) same code that I pulled off of the machine after I (recently) bought it.

I do have several small programs that were left on the machine from the previous owner. However, I reformatted the X and Y axis, so I had to modify the TC code for the new X & Y axes.

But, the code is basically copied from what was on there previously. All I did was essentially swap all the X variables for the Y variable -- and Y for X.

What do you see about the T and P codes that you are wondering about?

So that would be Humbolt then?
R/Todd

Write a test program

I think I'll try writing a simpler, shorter program to test the G26 format/syntax and see if I can figure out what's happening.

I have tried changing up which tool numbers that the T command is going from and to. In each case, no matter what the old tool number is, the associated G26 command gives the ERROR 16.

So, it has to be something with my formatting, syntax, or placement of the G26 block.

Let ya know how it goes. Thanks.
R/Todd

Maybe someone here that knows Fagor can decipher that code, but to me it looks like it was programmed by a tweeker ...

First off-

Have you homed the machine?

The only time I use "T" in anything is to call up a tool. T 1.1, for example could be your first tool.

Second, all of those G codes can be on one line.,

Third the only time I use "P" is in a canned cycle program.

PM your email address and I'll send you a great manual on programming the 8025.

Pat

G26 is not a format, it's a conditional jump.

You really need to look over this operation manual I have. I'd do it before you proceed further.

I'm not familiar with this code, but a quick look made me wonder.

Shouldn't all the P49 in this section be P45?

The F29 in this line confuses me, as well.

Thanks for the help

Pat and Screen,

Thanks for your help.

Home - Yes, I have homed the machine, and I can run simple programs on it. I still don't have the spindle operating yet, but working on the powering of that. Trying to determine the best way to get 380V 3phase from single phase 220V to feed the beast with.

T's - This machine has 6 tool pockets, so each program must start with a statement of which tool you want to use for this operation (e.g. don't want to profile cut with a drill bit).

P's - P's are "Parametric" variables. The machine allows for up to 255 different variables that allow you to do stuff like this TC program. They can take whatever value that you assign to them, or whatever value you have the program calculate for them.

G26 - I understand that the G26 is a conditional jump, what I meant was maybe I had the format or syntax of that block wrong, or that it was in the wrong place.

P49 - This came from the old TC program and I believe that it is just a "dummy" variable. The G26 conditional jump code just looks at whatever the previous calculation was and determines if it was a 0 (zero) or not. It could just as well be P149 - I think.

P29=F29 - this is a parametric statement that assigns the value that the machine currently has for the tool number in the spindle to the variable P29. The programming manual just says:
F29
Nxx P27 = F29
Block xx, Parameter P27 takes the value of the selected tool number.

Does this make sense? Do I understand it correctly?
Thanks for your help.
R/Todd

I'm on dialup in the shop now, so I have to wait until I get in the house to send the manual.

The easiest least expensive way to convert your single phase to 3 phase is with a VFD.

FM50-203-C

I haven't needed to use parametric settings so I don't know about those.

A typical tool line like I use would start like this:

NO (PARTNAME)
N10 G90 G95 S750 T21.21 M3 M8 (FACEISCARTOOL)

Are you trying to run in block mode?

Why not just run in auto mode?

I'll send the manual within the hour.

Also- are you confusing your "P" machine parameter settings with programming? Don't want to do that. What modes are you using?

I have considered this, and I do have a VFD that came in the elecrical panel of the machine. The problem is, you can't get 380V output from a 220V input.

Since your machine is not currently set up as having an automatic tool changer (Parameter P601(5)=0) you do not have to include an M06 with your tool change. If you do have an automatic tool changer, then P601(5)=1 and now an M06 must follow your Tx.x

This M06 must be in a block by itself - not allowed to include any other T,M,G functions.

I suspect that this is why you are able to get so many functions on a single line (a good programming technique to cut down on file size).

I'm just currently using the block step mode to try to find out where the machine is getting upset with the code. I've tried the auto mode and it does give the same results, however.

No, the parametric programming is different from the machine parameters - altho they sound the same and they are both designated with the letter "P".

Thank you very much for helping me with this. I will no doubt be able to put your 8025M expertise to good use.
R/Todd

Manual sent.

I'm setting up programming for my mill soon, and I would like to incorporate tool changes for sure. If you could post some pics of your tool setup that would be great.

I will be coming down to Redding this week as I just learned the Cold Roll I picked up Friday at Gerlingers was bent to crap by the kid who filled my order...

Thanks for the manual

Thanks for the manual Pat. I'll pull it down from the email soon.

I will include some pix of the tool changer set up in a reply to your email.

That sucks that you have to make a trip down the hill just for that.

I've had a little success with the TC code. See my next post.
