Maintenance and the use of Loctite 242

Now that a bunch of you have had your machine for several months, have you noticed during routine maintenance any of the bolts loosening up on the X gantry to the Y slides? Did you or would you recommend the use of any blue Loctite 242 on the bolts during assembly? Or the use of hex lock nuts?

Not on the axises - but I have lost a bolt on the dust show that holds on the protection ring in the center. Took me a while to find out where it came from (which always freaks me out when I find a random bolt laying around).


I just had the same thing happen to me with a fastener from the dust shoe. I found it in one of the threaded holes in my wasteboard and knew what it was as soon as I saw it. I checked the other two and they were both loose, so I did put a little bit of blue loctite on all three.
