    Default FC350BJ circuit board for X2 mini mill.

    Anyone out there have a circuit board to suit X2 mini Mill, FC350BJ of the first generation, looking for the transformer, or details where one/similar could be found.

    I'm actually after the transformer for one, I already have several boards, just getting expensive to replace the whole board each time.

    Kryn,
    Do you have any specs for the transformer which may help to find a relacement / substitute?

    Thanks Bob,
    Tried to load a photo of the transformer, but couldn't get it to copy, it was emailed to me by Amos.

    What is printed on the transformer is ; Power 2VA NoE2-4511
    I/P 220V
    O/P 15V015V 0611
    http:www lyt-hy.com

    Have tried to contact/look up website, nothing showing in reference to the transformer, just loud speaker stuff etc.
    Amos has ordered a 110V unit and is going to fit some doda to it so it'll handle 240V . Just thought I'd ask here, as you never know someone might find/know where to get one.
    Regards
    Kryn

    I found lots of transformers with those specs but without knowing what it looks like, it would be hard to recommend one.
    I'll have a look in my X2 tomorrow.

    Hi snowyskiesau, Thanks for that, would be interested to see where one could be found.
    Tried to copy and paste but couldn't get it to work, the circuit board is FC350BJ/240V, what is called Generation 1.
    Regards

    The previously mentioned report on the Sieg controller has a photo of the transformer and it shows 5 pins - 2 for mains in and three for 15V+15V out, centre tapped.
    I can find a lot of transformers with close specs (slightly higher power) but none that are centre tapped. All have two separate windings. Possible to wire in but not as a PCB mount.

    Not that it's of any help to you but the 110V version is readily available for about $US10.

    Hi snowy, the 110V unit is what Amos has ordered, and is going to fit some dodad to it to be able to take the 240V power .

    hi Kryn,

    I'm actually after the transformer for one, I already have several boards, just getting expensive to replace the whole board each time.
    Kryn
    Are the other boards 'dead' and if so, are the transformers the cause in each case?

    Two thoughts - if the transformers are OK, can you use one to replace the dead one in the board which Amos is repairing?
    On the other hand, if the transformer is the cause of failure in the other boards, what is the cause? Replacing the transformer is probably only a short term fix. You may need to be investigating other possible culprits both on the board and also in other parts of the system.

    The transformers are very low amperage units (less than 100mA). I would be looking for any other problem before putting the repaired board back into the system - unless Amos has found the component(s) on the board which is causing the transformer failure. I have not found any reports on the internet which suggest there is a failure (design fault for example) effecting a significant number of users, "so why yours" is the question I would be asking.

    Bob

    Hi Bob,
    Amos sent one board back that checked out OK, but still won't run the mill. He has replaced some of the components and resoldered the back to check for "dry joints".
    I've a friend coming around later to help me, hopefully, sort out if there is a problem elsewhere.

    It's a bit like, why is my mill so troublesome in respect to gears and boards, but no one else has problems. I can even break metal gears, taking what I think is a light cut.
    I know very little of the electronics side of things, car and house electrics I can work out, but this stuff is too complicated for me.
    Regards and Thanks
    Kryn
