    Mikini problem

    I fired up my machine after sitting for several months. I turned it on along with the computer to warm it up. While moving some stuff around the power strip that my computer was plugged into shorted and popped the breaker.
    This may be two separate things... my computer will not boot (didn't before the short) and now the mill will not operate.
    This is a version 1 machine. The control panel will not come to life though I get a beep with the 'start' and 'stop' buttons and the coolant will operate... nothing else.
    I pulled the control board and found this under the LCD screen... upper left corner.

    I'm pretty sure 'L1' is not suppose to be a tiny charcoal bricket. Any idea what this component was?
    I'll put a call into Phil and see if they have any of these boards around.
    The machine had been worked well for several years and did a lot of milling.

    I now believe it was an inductor. Does anyone know the value of this component?

    Sounds like you have a high impedance ground line and your power is obviously out of spec and are probably not using the right kind of electricity...

    I think I may have put imperial electricity through these metric circuits. Perhaps I should divide by zero...

    Circuit boards are removed and shipping to Mikini in the morning.

    Fingers crossed.

    An update...

    So far, main control board and from panel are dead... about $1500.00 worth.

    Phil suggested I send the rest of the electronics, transformer and spindle motor to be test which I felt made sense. Replacing boards only to have them toast again isn't wise.

    So, I've sent the entire electronics package off to Mikini.

    I'm also investigating alternatives to replace the dead bits is the Mikini cost for replacement is more than I can stomach.

    Something I ran across in my web travels was this site.

    I find this interesting for all sorts of reasons. I mean how many Mikini 1610Ls are out in the world? Less than 50 I would hazard a guess. And yet some third party is doing repair work for the boards now hmm. Anyway I have not tried them but I may try them out the next time something dies. Just thought I would pass it along.

    Cheers, Allen

    Wow, I find that extremely interesting. Although it seems that that site is a generic catch all for CNC repair and happened to put the name Mikini in their list of manufacturers.

    Maybe we should call them and ask them what kind of problems they see with the Mikini electronics.

    Checked out the company (google search) and found this link.

    ACS Industrial Services? - Practical Machinist - Largest Manufacturing Technology Forum on the Web

    They had a few experiences that you might like to take into account.

    I can't get the link to work but just google the title "ACS Industrial Services? - Practical Machinist - Largest Manufacturing Technology Forum on the Web" and it will be the first hit at the top.

    Apparently ACS Industrial sucks and no one should use them.
