Has anyone else had a problem with the seals on their ballnuts coming loose? I've got 2510 screws on my X and Y and I have had the seals randomly come loose several times now. I can push them back into the ballnut housing but there seems to be an issue with the mechanism that's supposed to hold them in place. So far I've only been machining wood, but this still sucks that dust can get into the ball nut, and would be absolutely unacceptable if metal shavings were to get in there. I've been trying to get a hold of George, but haven't heard back. I'd like to know what's causing this, and if there's a solution to fix it as I can't keep running the machine when these seals are failing.
