    Is the new drive just like the old? Not real common to use a Yaskawa spindle drive on a machine with Fanuc CNC.

    Most controls comp on any reversal, MPG, jog button, programmed motion etc. There may be some that do not comp in MPG or manual moves but I have never come across one. A control that did not comp...

    Having a gap between the faces prior to tightening the bolts is how I was taught, as well as just making good sense. The outer races of the bearings must be captured. Once tightened, the gap will...

    In the drive or the CNC?



    Is the replacement drive just like the original? What failed on the original that made you replace it? If it was some kind of catastrophic failure, that could...

    The loctite idea should be OK. Maybe 680 which is pretty viscous would be good to "fill" the wear area on the shoulder.

    If I was facing the same issue, I'd figure out the new stack height of the...

    It's a POS homeshop "CNC" plasma and the OP is surprised it does not work like "it's supposed to"? Definitely a better topic for the zone where the OP and other hobby folks can oooh and ahhh over...

    That's how I read it. That is why in an earlier post I said there must be some "conditioning" happening in the DC-DC module inside the CNC. I can imagine the CNC reliably using the 24V with that...

    I would bet that the DC-DC converter in the CNC has some filtering/power conditioning going on. Even for the 24VDC out at CP2 for I/O use.

    Here are the performance specs from Fanuc for the...

    The reason for the higher end controls was not due to reliability concerns, it was because we were buying higher performing, premium CNCs (predominantly Makinos) rather than commodity level machines.

    Certainly worth trying. Unplug the power to the CRT and CNC before you power it up with the cap installed. Measure the DC voltage with the cap in place and make sure that filtering the ripple does...

    I downloaded it and had a quick look over. Just enough to understand their circuit continuation labeling scheme and get a gist of their organization. I'll spend a bit more time on it tonight.

    I would scope all the power supplies. Some Fanuc models power the control from an external 24V supply and the internal module is a DC-DC conversion circuit to create the other voltages needed. ...
