@arnold_r_clark got any links to that admittal?

Thats open to debate, and current debate is telling that the "inventor" has admitted to having plagiarized the whole thing from Annex Engineering
Pony up with the proof in this.
I am begining to grow tired of your compaign to slander Euclid.

@mendelevium BLTouch can suffer from inaccuracies from heat and magnetism. Anything with onbaord electronics will suffer some sort of drift at temps >80C.
full disclosure: I am the creator of Euclid Probe. you can buy a kit or roll your own from the git repo. I think you will find it suitable for your needs.
Induction type probes will also suffer from some drift at those temps. Trying to get the device close to the nozzle also creates some difficulties. Voron users have give us feedback that they switched away from those specifically becasue they melted the housing being too close to the hot end.
The limitations on it are the temperatures for the components. Most switches are rated at 75-85C. For highter temps, we have kits that have components that are good for service at 100C and 125C.
DIY solutions that rely on friction, glues and similar suffer from durability.

@arnold_r_clark are you really this petty? do you have nothing better to do than actively campaign the work of others?

Ignore him.
Your probe is well made and is accurate and repeatable. The only "downside" is having to find a place to mount the dock, which is not an issue if you are designing a printer from scratch. On my first printer I had to add a small (Nema 11) linear guide (50mm travel) to move the dock into place as needed. It works just fine.

@fcwilt i use a little servo to pop mine out https://www.youtube.com/shorts/wlnXIud-uro

If you are going to make a claim like that is it up to you to provide the proof.

That was clever. I didn't think of that approach.
Did you design the "arm" yourself?

Sir if you consider it to be "petty" in trying to provide others information that certain entities do not conduct business in a fair and open manner then yes I am guilty as charged.
Please stop harassing sinned6915. I've read every single post here and I don't think it's warranted at all. If you have concerns about the technical nature of the device have at it, but this isn't the venue for personal slights.

@mendelevium Getting back to the original question which asked what is the best way to probe Z regardless of cost, I believe my setup fulfills that criteria. Essentially it consists of a kinematic hot end mount which constrains the hot end from any movement in X and Y but allows it to pivot upwards against a spring. The mount is at the front of the hot end. At the rear of the hot end is an adjustable brass bolt which makes contact against a flat brass plate. Wires connected to the bolt and plate make a switch. So the physical stop is also the electrical "probe". When the bed rises in Z, as soon as it touches the nozzle, it lifts off its seat which breaks the electrical contact. So the nozzle itself is the probe which means there are no offsets between the probe and the nozzle. Two pieces of brass making a switch is as simple and reliable as it gets. To home Z, I always heat the nozzle to soften any blobs if filament and my pre-print macro always heats the bed and nozzle before homing which takes care of any thermal expansion effects.

By any chance have you heard of the "Cherry Crosspoint" design?

I hadn't until I "googled" it just now. The "switch" has been working fine for a couple of years but if I get any problems, I'll look at getting my brass parts gold plated

@jay_s_uk That servo arm is as cute as a button, I like it.
