Jog Box Drift

[#2#]

I know this has been discussed before but I have a problem...

My CMM will begin drifting when the "enable" button is held down. It does this in both the X and Y axes (never Z). I know how to take the back off of the box and adjust the potentiometer to get it to stop drifting. The thing is that I will do that and then a few days later it will start drifting in the opposite direction!

This is driving me batty! I don't want to have to take the jog box apart every few days to adjust this. I can't understand how this could keep changing. I am wondering if there is a problem somewhere else that may be causing this and I am just compensating by adjusting the pot. Any help/suggestions?

Order a new assembly. In the mean time bang the jog box on the surface plate really hard whenever that happens. This will get you by until your new beefier joy stick/potentiometer assembly arrives.

Whadaya know, banging it on the plate fixed it. Guess I will have to order a new assembly. I'd give you rep for this but well, see Wes's post.

I've had to do that as well. When I started at this company, the jog box was doing just that. I was told, just hit it on the plate - that fixes it. The first time I had the machine calibrated, I told the service to bring a new joystick - fix it right and be done with it.

I have had that problem several times. It usally is because of my clummsy feet that nocks it off the table. My co-worker had the problem the other day and it was the circuit board thing that came unsnapped. It had little white clips that came out. You have to be careful putting it back together or you will pinch a wire. We have replaced two in three years. I have adjusted the up/down a few times also. The parts they make them out of are plastic. They are not cheap just cheap made. Have a great day and Good Rep to all!
