    Hey guys,
    Just a public service announcement...
    I was in the process of installing some custom CNC Pot brackets this morning and when I disassembled the old brackets it was very evident that my POT's (Bourns) while would turn, were very tight. I cleaned and lubed them lightly with a synthetic oil and it free'ed them up just fine. I also at this time lubed all pivot points and rod ends for good measure.
    So.... when things are working great for months at a time, please do not forget to spend the time and perform some PM... Your machine and your wallet will thank you later!

    Oh forgot...
    Here is a picture of my POT brackets

    I can second this, one of my hall effect pots bound up on me recently, killing one of my drivers and bending the connecting rod. After cleaning it out and re-lubricating the shaft it's all back to normal.

    My regular preventative maintenance is to check and re-tighten the grub screws of the flexi links between the pot and the motor.

    While I'm sure these connections shouldnt come loose, I have lost the link between the pot and the motor causing the motors to drive hard over to the extremes of movement.

    But I hadn't thought of lubricatingthe pots. I have some spray lube and contact cleaner somewhere at home. Better pull that out and give each of the pots a little squirt.

    Yeah, I was surprised at how tight the little pots where, almost could not turn them by hand.... Cleaning and lube got them going perfect again.

    lol.... Thanks, Yes I drew them and had a machinist at work cut them for me.
    They would be expensive .... They where hard to hold in the machining jig while cutting.
    I certainly can post the .stp files though, see attached
