Program Stops in HAAS and Doesnt Throw Alarm

[AustinMLab]

Program keeps freezing, ive had this issue with other programs before with fusion. Worked fine all day yesterday, started program up this morning and my faceing op freezes on the 6th part, no alarm. The only way ive been able to fix it in the past is by changing lead in position or in this case flipping the pass direction 180 and then it will run fine. Ive never had it do this with any of my mastercam programs but most of my large production fusion programs will do this at random. Machine is a 2011 HAAS VF3ss. Attached is a video of the issue and the program. Thank you to whoever takes the time to read this. Also apologies with the video cutting at the end, youll have to pause it to read the code, only way i could get the video short enough to attach it.

Its now also doing it (same program) on my g154 p1 boring operation. Same thing just hits that line of code and freezes, no alarms.

So you're saying that you can run 5 parts of the same program and on the 6th part your machine will just stop?

[AustinMLab]

No its all depending on the operation and its all random, it just stops. Seems to be something with lead in lead out locations and whether there is a lead in radius or no lead in radius, or lead out radius. It also can be fine one run then a few runs later it randomly freezes.

[AustinMLab]

Every time ive had this happen the fixes include removing lead in and out radiuses and changing lead in location. Can be different jobs completely, this is just the job im running today thats giving me issues.

If it was doing it all the time at the same spot, I'd be looking at the output code. As it's doing it randomly, I'd be looking at something in the control itself. I appreciate that your MasterCAM code doesn't result in this gremlin..

[AustinMLab]

Yeah i was hoping mentiong mastercam would narrow the problem down, seeing as my machine plays nice with that post as opposed to fusions. Ill post to this thread in the future if i figure out where this gremlin is hiding as it seems to found a particularly good hiding spot. I want to figure this out because its killing my ability to quickly get lights out production programs onto my machine as i have to babysit it for a few days until it starts causing the issue.

Have you tried loading the program into memory and not running from USB?

[AustinMLab]

I have not, thats good idea. Ill give that a shot

[AustinMLab]

Not enough disk space on the machine memory 😕

[seth.madore]

For how many parts? Try one or two and see if the problem persists.

You may need to go with sub programs of one part, or write up an increment macro.

[dwilliamsFM6K4]

I mean that's probably the issue then, the machine has to cache the program even if its on a USB etc also would explain some of the intermittence

Can you drip feed it? That's what I do with my super old HAAS

[AustinMLab]

That all makes sense, thank you for the insight, I'll give it a shot and
let you know how it goes.

I’m having a similar issue when it gets to the lead out on a 2d chamfer at the end. It just stops feeding and won’t go to the next line. No alarm, coolant and spindle continue not perpetuity. VF3, this is our first program with fusion, all others have been mastercam with no issue.

I've had this too. Just power cycle the machine.
