I've been thinking about this a lot for my upcoming large corexy build (V-Core 2.0/400x400), and am really wondering what to use.
As I'm really throwing some coin at the build plate and Z axis, I'm even considering just having one of these on one of the Z axis uprights, and not even having a probe on the hot end.
I've got a bunch of them here, and I've see the Dentist pulls some very good repeatability tests, so I'm certainly open to it. If the bed measures up convincingly flat, it's even likely.
But...in the 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 are out there actually any better?
