KM3 - Motion error detected on X

[rbalister]

I've got my KM3 up and running and I thought all of the bugs worked out of it. Everything in the controller cabinet has been cleaned and reinstalled. I've been playing around with it attempting to get the hang of working with this machine. I've even got it loading toolpaths from a desktop on the other side of the shop. Today I've tried driving it with a toolpath from a CAM package. After running for a while I got an error on X. The error was "Motion error detected on X" After clearing it and restarting, it would run for a few minutes and then it would do it again. Before I start digging into this too far, does anyone have a suggestion of where to look on this one? It seems to happen mostly when it is doing slow moves on X however I can't seem to reproduce it using the wheel on the console.

rbalister,

This is just something to check.

On my Hurco I had drive problems and other stuff, too.

Sort of a "ghost in the machine"

While doing the retrofit, I pulled the servos to change the encoders.

The flex coupling on the x axis was broken. It still had tension and would move, but the coupling would drive with a [spring-against-spring] effect.

This is just something you might check.

Thanks JAckal. I'll check the coupling next time I get out to the shop. I'm not sure if it's related, but when I first got the machine I would sometimes have errors calibrating the X. When it would calibrate X the table would shoot off to the +X instead of the -X and then I would get a servo fault. Cycling the power would clear it. Later I took the controller apart and cleaned all of the boards and haven't seen that error since. I do remember some goo on the connectors. Maybe I need to hit them with some contact cleaner again. It seemed that the goo had wicked it's way into the connectors on the controller and no matter how much I cleaned them it would come back. It was probably cutting fluid.
