Slider Block Failure fixed!

[dspy8083 1]

I print with an enclosure and with pc so it gets a hot build chamber which has promoted my slider block to fatigue, letting loose my X and Y rods.  
 

After a second set of failed slider blocks I figured an effective, very easy solution.

 

 From the internal boss that holds the spring, I drilled out the internal hole with a 1/16” drill. Then used a very small sheet metal type screw.  The head is the mount for a small O ring to suspend the x/y rod!  
 

Ensure the screw head does not protrude out too far which could cause interference with machine operation.

 

i hope this helps someone!

Notice the screw has adequate clearance during print head's full range of motion.

Out of curiousity how did the fatigue affect your prints? I have some weird things happening so,etimes and also print with an enclosure and just trying to eliminate variables.

At the minimal end, you can get layer height inaccuracy if the print head moves up and down due to play.

 

 In my case the whole rod fell out mid print!
