Hi guys, I was having some trouble with this Prusa X-end:
[www.thingiverse.com]
The springs that go onto the nuts that the threaded rod goes through kept either jamming the threaded rod and blocking my Z-axis which resulted in missed steps, or the spring would press itself through the opening on the bottom of the X-ends.
I wanted to share my solution to this problem, I have found more people that had similar problems, so I decided to make a simple explanation.
By using nylon M8 washers, and trimming them to the same size as a M8 hex-nut, and then inserting them into the X-end, will make sure the springs stay nicely centrical to the M8 threaded rod and they won't jump out the bottom of the carriage.
Here's the slideshow that explains all, I used a rod and two nuts to clamp the two nylon washers so I could easily cut them to the same outer size as the M8 hexnuts.
The cost for two nylon washers in total was about 0.25 euro for 6 washers. So this solution cost less than 10 cents :)
