Hi all,
Just half way through my first build (Prusa Mendel) and was wondering if anyone knows of any good sources for the Z Axis ID Springs online or in the UK?
Any links or advice would be great.
Thanks

I've found these compression springs [uk.rs-online.com] on RS components website, as far as I can tell they fit size specs -
Though not sure on the compression rate, weather too weak/strong?
Thoughts?

- inner diameter 8mm (8mm threaded rod)
- outer diameter 9mm (will fit in hex gap 13mm)
- 28.5mm length (min 14.3mm)

Thoughts?

Hi Simon,
Yes, you should use them, it eliminates backlash and makes your layers look smoother. You can get a selection or individual springs from Maplin in the UK.
I got mine from CPC but others use Maplin.
Good luck with the build.

The RS ones are a little too long and may have quite high compression
Try this Kit from maplin - [www.maplin.co.uk]
You will get at least 8+ springs that will fit just fine.
And then you can fit some bigger ones on your heated bed, don't use the ones from BIC pens - See here

I think you only need them if you z-axis binds or you want to print in zero G.

my x-end-idler was binding a bit on the z-axis. i couldn't find any springs locally that would work, so I cut a small section of 1/2" vinyl tubing and used that instead. it works very well. i don't need it on the other side because the stepper motor is heavy enough to keep it from binding.

I found the same when I tried to fit the springs! So I slightly adjusted one end so they wouldn't push through the bottom of the plastic part.
