    Re: How can I eliminate chatter

    As Mactech pointed out the lack of rigidity is the primary cause of chatter. I have cut thousands of lbs of steel on mine. Mine was singing as well. I was concerned I had a bad spindle bearing, but...

    Re: New owner Torus Pro

    Yes something is awry, it should be able to take a heavier cut or go much faster. Here's a couple more vids of cutting aluminum with nice big chips to compare. I'm using a Hitachi VFD.

    Personally, at $5k or less it looks like a pretty good deal. I would go into it like Bluehands stated. Buy it for the casting and budget to restore and replace electronics and wear items. (bearings,...

    Re: drive issues

    I would try turning down the gain on the servo amps. It sounds like resonance. When all three drives are powered, the resonance of one loop is throwing the others out. Mechanical slop can intensify...

    Re: drive issues

    Without knowing your setup, my guess is you need to tune the servo loop. The tuning is not in the UCCNC. The loop is between your G320 and the servo. Once this is stable, then setup / calibrate in...

    Hi Bill,
    I have installed a few UCCNC systems but I am not familiar with the richauto. From looking at pics it appears you will need motor drivers for each axis or you can fabricate a plug that will...

    It may be your meter, you mention moving the selector to AC scale. If not auto sensing it may not play well measuring DC on AC setting.
