    There's still something else I gotta figure out about a pulsating sound that wasn't there with my older PP but anyway, it works, voltages are fine. I also put a line reactor ahead of this new PP to knock out a lot of the noise/harmonics feedback into the mains and that seems to be working pretty well.

    Now that doesn't mean that its the source of the issue with your machine, could be something else.

    With my 2 cnc's I put T3 on the right, always been fine here but maybe some other machines need it in middle or other side.
    Thank you for the update, It's about the only thing I haven't tried yet. I will give it a try and report back.

    I did put my phone in a position to record my volt meter while I started up and there was no loss of voltage, so I'm still thinking this might be to much going in and tripping the 552 error.

    Any luck sorting this out?


    Not sure why this thread got moved down here as it may be a machine and not a converter issue in this case.
    Though I still have a couple things to sort out with mine when I get the time, gonna try to scope it and hopefully see wtf's going on.
