Machine stopped in middle of program.

Category: AXIS

-power brownout
-lighting strike even several miles away
-processor had a hiccup
-failing power supply
-failing memory or memory controller
-failing capacitors on PC
etc
If any of the last 4, the issue will occur more often with time.
If the second, not much you can do.
If the first thing, and if this is a parallel port setup, and this happens again, see what equipment did you turn on in the house/shop/neighborhood, as big power draw equipment can cause this, easily, and they do for sure cause power brownouts.

Machine stopped in middle of program.

Category: AXIS

Greetings,

I was machining two parts that I have run before at least 30 times.

First part machined as expected.

The second part got 3/4 through the program and the spindle and axis motors stopped.

Also, the AXIS screen was frozen up. No response to keyboard nor mouse.

I turned off the power and rebooted.

Next I started LinuxCNC 2.5.5. All went well.

Reloaded the program, dialed the part back in, and reset Z zero of the cutting tool.

Pressed Cycle Start and the program ran fine.

So, what happened?

Is there an error log/file I can look through to determine the cause of the shut down?

More clues.....

LinuxCNC 2.5.5
Smithy 1240 Milling machine

Cheers,

Dave

thanks vp, that will save us a lot of work. we need to archive this shit for the repo or something

darkpheonix - that is good to hear

spyder - this is my WIP remora spindle template (no encoder edition). murphy is also using it. some might be duplicate to what you have now

Is there a different repository? Just did a git pull

What are the chances of getting this setup working?

Category: Pick and Place

Well with my project I got interested in other things and haven't spent much time on it in a while.
Partly the placer head desperately needs updating to modern day equipment. Cable and pulley
for the Z axis is in my opinion a terrible idea but the machine was designed in 1993. We have a few
other PnP machines where I work so this one was more or less an experiment. Plus work just
doesn't seem to ease up.
 

I tend to post and then forget about LinuxCNC for a few weeks lol, forgot to check on this. I just converted the machine I intended to be to a laser cutter.....since I needed one and figured I could actually get that going. I had a belted see-saw Z, which I just stripped to mount the laser to the carriage.  I did redesign it to be a rack and pinion see-saw so that way I could easily swap out the PnP nozzles for and the laser and have a compatible Z. I haven't machined it yet though

It'd be nice if there was a proven simplified PnP setup for LinuxCNC. I'd be alot more inclined to finish the mechanical stuff if I knew software wasn't going to be a long drawn out slug fest. Hopefully somebody beats me to it, if not maybe I'll get there one day lol.

I do find flexGUI to be a pretty easy (ish) way to get a purpose built UI going. I was able to convert the one I was making for my mill into a laser UI fairly simple. I'd definately use that to tackle the PnP thing if I were at it right now.
