    Default Help with Lagun/Pacific FU-2 Mill

    Hi all,

    I have a new-to-me Pacific FU-2 (which I believe is the same as a Lagun FU-2).

    I had it running for a few test cuts but after a while it gave up the ghost. It slowed down while I was moving the table and now it's a brick. The table won't move, the spindle won't turn and the pump won't pump.

    A friend who knows his way around this stuff much better than me came over and had a look and confirmed that I'm not bumped up against any stops or anything like that. He also brought a multimeter and did enough poking around to think it's an issue with the control circuit. His hunch is that the stop button is being constantly triggered.

    This is where I need some help. I haven't been able to find a manual (the machine is different to the FU-2 LA, which I think i saw a manual for) and he wasn't sure what voltages to expect across the breakers if his hunch is correct.

    Does anyone on here have a manual or a schematic they could share? Alternatively, does anyone have an FU-2 they could test the voltages on while the stop button is pressed?

    Thanks for reading!

    Cheers,
    Tris.

    If nothing works then the problem the the electricity is not getting to where it is distributed to all the various bits and pieces. It should not be too hard to diagnose.

    Hi Tris,

    Stop button pressed in ! On some you have to twist the button to release it.

    It will be wildly embarrassing if that's it. I'll check in the morning to make sure, but I don't think that can be it. Firstly, I used it a few times before it stopped working (and definitely pressed the stop button several times). Secondly, both of us fiddled with the button quite a bit during trouble shooting. But I will check in the morning, because it's definitely the sort of mistake I could have made.

    What? So it's not just me?
    Hopefully it will be an easy fix.

    Sadly, it wasn't just the stop button being physically stuck on.

    I'm not familiar with that mill, but assume your friend has confirmed that power is still getting to the control box and that any fuses are OK?
    Is it of the age where it has the old milk bottle style fuses? I've had issues with them rattling loose.

    Does it look like a pretty simple control box with maybe half a dozen contactors, or is it lots of components and an equal amount of wiring? Just trying to get a feel for whether its simple electrically, or more complex all electric control like my TOS FNGJ32. Can you post a photo of the inside of the control box?

    Good news: My friend came over and fixed it! It turned out to be a thermal overload that needed to be reset (we did another one but missed this one first time through). The thought is that the thermal overload was triggered because the ways were too gummy at the extremes of the travel. So with any luck I'm back in business after doing a bit more cleaning and applying a bit more oil.

    Hi Guys,

    My experience with thermal overloads, particularly non adjustable types, is that they will trip more often the more times they are overloaded, they seem to get more sensitive with use.

    Default Pacific FU 250. Mill

    Just come across this thread when posting something similar. When we took delivery some years back the feed motor kept tripping the push button CB on the circuit board turns out the main feed motor has brushes and the commutator was quite glazed up. Cleaned up and still running .
