Design Z Axis End Stops Best Practices

Hi all !!

What is the most preferred End Stop for Z axis ? ( taking under consideration accuracy,better bed levelling, less maintenance and cost )

Should Z Axis End Stop be fixed or should be adjustable what are the pros and cons for both the systems ?

Hey,

On my 3D Printers I use simple push buttons and lever switches.

I know you can use optical and even Hall Effect switches for homing.

You can get 3 push switches for a few Dollars/Pounds and I don't see the benefit of buying an optical switch for 5-10x the cost!

I have no experience of using these alternatives on 3D printers, but I am yet to tell myself, "Dam, I wish I had better switches!"

In regards to the Adjustable Z height, it is easier if you do but it is not essential.

What you can do is put a rough estimate into your config.h and alter it from there.

Any fine tuning (0.1mm) etc can be done in Repetier Host and Slic3r if you use those programs.

Hope this helps!

There isn't a preferred. Mechanical is the most popular. They are generally accurate, should last as long as your printer, and really don't have any maintenance. And their operation is pretty simple. But they aren't an "elegent" solid state solution like a optical or hall effect sensor. It's also possible that they may need recalibrated every now and then if a spring weakens or the lever bends slightly.

Fixed. Do any adjustments in the firmware. Just my .02

Hall effect sensors that run on 5v cost somewhere in the 20c region in small quantities. I am contemplating switching from mechanical to hall. I bought a set and will be testing them out.
