Re: VMC40 w/88HS control

The program so far is:
N1 G90 G80 G70 G40 G17 G0
N2 (EM 0.750)
N3 M6T5
N4 S2500 M3
N5 G0 G90 X-.88 Y.5 E1
N6 H5 Z1. M8
N7 G1 Z-1. F8.
N8 G1 Y-6.5 F.8
N0 G0 Z1.
(and more...)

The problem is that the program stops after N6. I'm sure I'm doing something wrong but what is it????

[gaswiz69]

So far, program looks ok. You may want to check to make sure there are no values in last home position or fixture offsets for an axis that is not there.... ie an A axis that has been disconnected, or a value that is not suppose to be there in the offset page.
What exactly is the machine doing? Does it generate a fault? If you press slide hold, does the machine go into "slide hold"? If so, then the machine is waiting for something, be it a sensor, or an axis move.

IS there any error codes? Are you running DNC? How old is your software? Email me your full program downloaded directly from your machine not a copy off your computer.
I'll check things out for your. Also include all offsets. Describe exactly what happens when it "stops". Does it just stop in place and the spindle keep running or does it dump out of the program and return to ENTER NEXT COMMANd?

Okay, it's Monday morning, I fired up and checked for unusual or hidden programs and I've pulled most of the rest of my hair out!
I did find three subroutines apparently left by the previous owner and one of them referred to T5...thought I had the answer. I deleted all three, re-ran my program and once again it stops (with the spindle running) after it executes N5. If I hit Slide Hold I get the flashing message Slide Hold. There are no error codes. There are five other programs, 774 thru 778, all labeled (Maint) and I figured I shouldn't touch them. I haven't pulled them up so I don't know what they say. I'm programming directly from the control panel and no DNC

[AKELLEY]

Put the H5 on its on line, I think it's trying to put the heigth comp on at the same time it's starting the cut.

[rdoty]

Tried that, all it did was drop the tool down to "gauge point" then up one inch then it stops. I've also tried the power down/power up but it still stops.
I'm completely baffled.

[JimBoyce]

Does line N6 need G43?

[AKELLEY]

N1 O1 PROGRAM NUMBER 1 NOTE PROGRAM NUMBERS ALL START WITH THE LETTER O NOT THE NUMBER 0
N2 G90 G80 G70 G40 G17 G0
N3 (EM 0.750)
N4 M6T5
N5 S2500 M3
N6 G0 G90 X-.88 Y.5 E1
N7 H5 Z1. M8
N8 G1 Z-1. F8.
N9 G1 Y-6.5 F.8

N0 G0 Z1. YOU CAN NOT USE A LINE NUMBER 0

DID YOU DO A SUM OF THE PROGRAM BY TYPING IN SUM AT THE COMMAND PROMP AND HITTING ENTER?
IT WILL TELL YOU WHAT LINE NUMBER IS THE PROBLEM

I RAN THE PROGRAM AS ABOVE WITHOUT THE LAST LINE AND IT RAN FINE.

[scadvice]

rdoty,

It sounds like it's waiting for something, an operation to finish or command. It should time out if there was a electrical or mech. problem.

Do as Neal asks down load directly, if you can, and send it to him. Tell us more about how you set the job up. (i.e. the preparation)
AKelly’s program is good, try it.
If it will not run:

How exactly are you turning the machine on and getting it homed?

How are you setting part home?

How are you touching off your tools?

In the tool offset page what does offset height read for that tool?

(In other words the basics first must be right. OK? Unlikely the problem but… you never know)

If you can down load the program do so and look at it in “notebook” then delete the original and reload from the notebook copy. I once had a program not run and that fixed it. I think there were ‘ghost’ characters in that one.

Sounds like there is something wrong in the E1 offset table.
Do you by chance have a setting in the A or B column?
If so delete it.

[rdoty]

To clarify, in the interest of brevity I typed the important lines of the program in my orig posting but so that it's clear below is exactly as it appears on the screen..

N0.0010 0101
N1 (BASE 21033)
N2 (TRIM LEN)
N3 G90 G80 G70 G40 G17 G0
N4 (EM 0.750)
N5 M6T5
N6 S2500 M3
N6.1 G0 G90 X-0.88 Y0.5 E1
N7.1 Z1. M8 H5
N8 G1 Z-1. F8
N9 G1 Y-6.2 F8
N10 G0 Z-1. F8

THE TOOL OFFSET IS 0.7500 -10.1262

FIXTURE 1 IS -3.6450 2.6980 0.5000 (No A OR B values and no other fixtures listed)

SUM is X=-4.525 Y=-3.552 Z=0.5000 (does that look right???)

at stop the screen displays:

H5= -10.1260 D0=0
F8 S2500 G1 G8 G17 G40 G70 G80 G90 G98
PROG NO. 101 BLK SKIP OFF
OPT STOP OFF
N8 ........

When I turn the machine on I do a CS. When I turn the machine off I make sure everything is at zero than do a CS then turn the machine off.

Not sure how I can download the program since I don't have any serial hookup yet.

[JimBoyce]

There is a feed rate of F8 this is 0.0008 IPM which would seem like the machine stopped.
If the feed rate is F8. disregard this reply.

[scadvice]

There is a feed rate of F8 this is 0.0008 IPM which would seem like the machine stopped.

I agree with Jim. Hope that's it.

Steve

[rdoty]

The machine code is actually F8. so it should be 8ipm.
Sorry for the confusion.
Does the SUM look correct, especially the Y being -3.552?
I keep looking in every corner of the machine parameters but I can't find anything that would cause it to stop. Is there some "look ahead" command that is in some obscure location that I've overlooked?

[DSIF]

G43 is missing on line7.1. The machine doesn't know the height offset for T5. I'm surprised it didn't crash.
Dan

[DareBee]

G43 is not required and the H5 is on the line with the first Z move - this is all good AFAIK

[HuFlungDung]

G43 is not required and the H5 is on the line with the first Z move - this is all good AFAIK

Why is no G43 required? There is an opposite option: G44 would reverse the direction of tool length offset (on a Haas and I assume others), so would it not be a good plan to spell it out completely, leaving no stone unturned, so to speak, when troubleshooting?

[Neal]

The G43 is a Fanuc style code and the Fadal is written to recognize it to be compatible with Fanuc written programs and not error out BUT the G43 code function is built into the standard Fadal "H" code therefore it is NOT needed is either Format 1 or Format 2.

Neal

[rdoty]

First, I want to thank everybody for their input.
Second, I want to tell you that the problem is now solved!

I won't go into detail or say what the issue was but I will describe the conversation that I had with Douglas at the Fadal Factory Support (great guy by the way). The conversation went something like this:

Me: Hi Douglas. I've got this problem that has me pulling my hair out.
Doug: Okay, describe to me what it is doing.
(I describe and the program continues to stop)
(I single step through the program and it stops)
(I read off the program line by line)
(I read off the X, Y and Z positions)
Doug: Now you say the machine is not moving? Bob, tell me what the feed rate dial is set at.
Me: Uhhhh, let's see, it's set at....uhhhh....(expletive).....gosh, Douglas, it's set at....uhhhhh...crap!......uhhhhhhh.....(faintly) zero.

I hope you guys had a great Thanksgiving and enjoy a very merry Christmas. Me...I'm going to go crawl in a hole!!

[HuFlungDung]

That can happen
