Worked thanks guys

@Corexy said in Plain old inductive sensor for Z height?:

he event my bed isn't flat I'm not so sure. I've got the IR probe on my other machine, and while the startup homing is always perfect it doesn't do a good mesh map with my Printbite surface. I was looking at going with a genuine BLTouch, but the reviews are mixed at best on that one too.
I'm really considering going to a good old fashioned inductive sensor, possibly the 12mm diameter body with the 4mm gap that seems popular.
I've just seen that Toms review video on Z probes ( https://www.youtube.com/watch?v=il9bNWn66BY ) while and I don't mind paying for a good thing, these inductive probes seemed to be right up there for performance and down there for cost...no moving parts either.
I'm using a Duet 2 wifi board. Will it run one of the 5v units directly, or should I go with the 6-36v . Will this board run a PINDA sensor correctly?
This is actually not a cost saving measure, it's more about reliable utilitarian operation. Are all these new probes that

I played with a bunch of sensors, some $80 plus and came to the conclusion a inductive sensor with a flexible steel build plate was best, always get a perfect zero. Some sensors advertise 5v compatibility but it messes with their trigger distance and accuracy. Just run it 24 and setup a voltage divider. Oh and make sure you test the output voltage with a volt meter, better safe than sorry.

I think a hi point mesh and reloading the grid is the way togo. How stable is your bed, is it removable ? If your printer is mechanically stable i dont see an issue with reloading the grid.

@Corexy
yes, the smaller bodies seem to have a closer trigger range, which might be a big deal but i wanted a good safety margin.
