After ten months, the next step of the evolution is reached. Only 10 more to get to the final mount 
At least, I could reduce the needed field intensity

Hall sensors 
I use a Hall switch on my X axis, just because it was the only thing I had laying around, and just put the magnet on the extruder stepper.

I also use reed sensor since few month, not like yours ( 6x24 mm cylinder) but I’m also really happy with them for the same reason !
Is there a compelling advantage of HE vs microswitch?
@Stephanie_A If the electronics are reliable, the proximity sensor should outlast a mechanical switch. One less thing to worry about.
@Stephanie_A In my experience, they are more reliable in terms of repetetive results. I still have a normal switch on Z, but going to change that soon.
Interesting! Rene, what type of linear rails do you use here?
the one in the picture are genuine HIWIN MGN15. I use MGH15 for Z, tho.
Thanks, Rene. May I ask you where you got those? Any online shops you can recommend?
I bought via official reseller in china
Just write an email to Alex Wang via njskt_ballbearing@outlook.com he is very nice and provides excellent service
This is so nice. Thanks for the link, Rene. The prices are indeed very good. May I also ask you which precision and preload class you ordered for your MGN15 rails?
normal preload (dont do free play) and normal precision.
And they are not clones.
With normal preload you mean type Z0 I guess?
Yes. the exact type is MGN15C-Z0
and for Z I am using MGH15C-Z0
