Please bare with my. This is my 1st thread

We just brought in a used Haas Model VF-E.
Set it up, Leveled it up.
Made a warm up program with all rapids and G90 / G91 moves.
All works great.
Just loaded a program from a smaller Haas.
All works great until it reads a feedrate.
The machine just sits there. It thinks it is cutting because it says running.

Any ideas would be helpfull.

Thanks

[JWH]

Make sure there is a decimal point after the feedrate.
Good luck.
Jim

[THREEPT82]

there is.
Any other ideas out there in cnczone land?

Save the program as text, in MS word etc & post it here, it will be easy to see if it is a program problem, or a parameter setting in your control

What parameters would control feedrates?

[WallyL7]

You're using rapid for the warmup?

On the program you posted I assume it gets to the G1 line and sits there with the spindle on?

[THREEPT82]

Correct.
It stops at " G1 Z-.1212 F22." but the screen says its running.

I took this program from one smaller Hass that runs great to this machine as a good job to start with and thats what I get.

[Donkey Hotey]

Just a stab in the dark here: is Inverse Time Feedrate turned off?

[mactec54]

THREEPT82

Put your program together like this sample & you won't have any problems

Make sure your warm up program is not doing rapid moves, should only be feed moves

[THREEPT82]

Inverse Time Feedrate turned off? I will check that.
Should it be on or off?

That is a section of the program.

[Donkey Hotey]

Inverse Time Feedrate should be off.

What about units? Are you in Metric or Inch?

Are the position counters moving at all or is it actually stopped? I've seen times where the feedrate is just so painfully slow that it doesn't look like anything is going on but, it's actually moving (like the missing decimal place).

[THREEPT82]

I could not find a Inverse Time Feedrate setting anywhere.

All is in inch and no movement at all.

[THREEPT82]

Does anyone out there have a PDF of an operators manual for a VF-E Mill?

[WallyL7]

They are all available online. haas.com

[THREEPT82]

On line has only new updates.

Im looking for an original 1998 machine/operator manual.

I downloaded the Haas site manual.

It was informative but most didn't pertain to my machine.

[WallyL7]

You sure it is much different? The 1996 machines I ran were very much the same as far as the operating manual to the 2006 I have...at least for what we are probably dealing with here.

I'll bet Donkeyhotey is on the right track as far as suggesting some strange parameter or setting. Any of the manuals should be able to get you on track regarding those.

I'm surprised none of our resident Haas techs have chimed in.

[THREEPT82]

I was just on the phone with a tech from Haas.

He gave me a few things to try which I will tomorrow but he didn't feel they will help.

I'm just trying avoid a service charge but if I need to, I will.

I will take another look @ the downloaded manual.

Thanks Ken

[WallyL7]

You may want to take a look at the Current Display Command page and compare it with the other machine when it is at that spot in the program just to see what may be different.

Otherwise - will the program run through on the graphics page?

[Matt@RFR]

Tim asks a good question: Will it run in graphics ok?

G91 G1 X5. F50. Run it in MDI and see what happens. Same thing for Y and Z. If nothing happens, try F500. or whatever your max is. I'm not saying this will prove anything, but it's free.

[Machiner1]

Could be that the machine is locking up on some cutter comp issues.
I have seen the older haas machines do weird things during cutter comp exit moves. I have also seen some completely ignore the feed rate commanded and run one from elsewhere in the program. Just a few things to check.

In current commands screen, does the active feedrate represent the programed feedrate?

Try removing the G41 and running the program without it. Just cut air. See if this makes a difference.

The older machines will look ahead and see something they dont like, but they will get hung up on a line way before the problem line. Its pretty aggravating sometimes.
