Requesting detachable Z-probe to be added to the config tool

sinned6915

@phaedrux thanks for replying to the specifics of my query.

I will look into adding them into the wiki.

as far as the config tool goes, I feel that the class of probes should get their own entry. the whats and the hows are what I am trying to start a dialog about.

its a herculean task to try and script and all in one algorithym for all cases- i am not asking for that.
there is no universal solution: it can be a fixed dock or a moving dock, and no 2 printers are ever alike. while there are adaptations to main-line printers, even between those, user preferences and specifics cause customizations.

at a minimum, i would hope that if someone checks an option box for 'detachable probe', that a couple of comment lines could get inserted with some basic instructions or redirect to the wiki.

thanks

@arnold_r_clark why do you keep making belittling and insulting comments towards me and the deivce I created and that has inspired many others to follow?

The request Is not about MY device, it is about the class of devices. Re-read my original post.

Its not as simple as you make it out to be.

Sir I am making neither belittling or insulting comments towards you, if you took my observation and comment that I feel the device being advertised is very expensive for what it constitutes of, and the valid question asking why you feel there is a special use case for adding an "extra" category for this "class" of device when it is 100% already catered for then that is a perception that YOU need to deal with instead of trying to blame others.

And having designed and formulated the RRF code for this type of "probe" years ago using spare components I had laying around at nothing more than the cost of my time it is 100% as simple as I make it out to be.

config.g settings are quite normal as the probe type is set to P8 (in RRF-3)

In your homeall.g after X & Y has homed you command the head to a traverse to specific location in a very specific direction/order using the G1 commands to send the head to the probe shoes dock location, you then tell the machine to take the probe shoe out of its dock in a specific manner again using the G1 command, then you allow the Z axis to home itself as normal, after homing (or probing) of the Z axis has completed you command the machine stow the probe shoe back in its dock again using the G1 command there is NO need for any deploy/retract commands whatsoever, as you are technically not deploying or retracting anything you are however collecting and returning the probe shoe to its dock which is all on the same plane.

All very simple commands which take only a few minutes to formulate.

As I can prove what I originally asked as being simpler than you make it out to be, my original question stands. if you take that as being " belittling/insulting" then for that I am sorry that is not how it is intended, I am merely trying to understand the thought process of why you think such a simple class of device to create and to get working in RRF requires a special category when a simple switch is already catered for.

Well one thing I have discussed with OP is a design change that would allow detecting 3 states (not mounted, mounted but not active, mounted and active) rather than just 2.

To achieve that would require a new type of probe using the analog capabilities of the input to determine the 3 states.

I think the MK1 Eyeball will do most of what you require with no need for any update.

Without the 3 states you cannot write bullet proof code to handle all possible situations.

@arnold_r_clark again, the point of my post is to add the class of detachable probes to the config tool. have the courtesy to respect the request despite you perosnal bias.

there are literally THOUSANDS of detachable probes out there between the Euclid and its imitators. they are replacing poorly performing BLTouch and inductive probes, and the ranks are growing.

go look at the diffculty that klipper has to make the detachable probes reliable and safe to use. its the wild west on that one becasue of klippers lack of standardization.

@fcwilt as we discussed, it may take some coding to get better detection schemes in place.
it would seem that to make that request more credible, getting it recognized as a viable device first would be a prerequsite.

This kind of detachable probe is very pupular these day in the voron community and it works very well. I have one on my printer, acting as z stop and z probe.

I think you should have the courtesy to respect the fact that a simple switch is ALREADY catered for.

It is also very telling from your own words that you feel that anything of the Class (as you put it) of "simple switch related probes" that is not produced by yourself is in your very own words "imitators" did you invent the idea of using a simple switch as a probe ? if so please provide citation of that fact.

the Euclid and its imitators.

The cynical could say that if you were to obtain a "special" category for a simple switch that, that could be used for commercial gain.

install and setup instruction formulated properly would be more than sufficient .

Also no matter how you try to paint it I have no personal bias, I only deal in black and white logical facts, I am not on any side of right or wrong, facts are facts and the fact is 100% that a "simple switch" is already catered for, and to mention klipper is irrelevant chatter as this discussion is about your desire to obtain special status for a system already catered for within RRF-3 NOT Klipper.

Not exactly so, you can work out two of those three states with NO changes to the (or additional) hardware

lets look at the logic of what you said which was:

not mounted, mounted but not active, mounted and active

Not mounted: RRF-3 can be 100% coded to tell you if the switch shoe is mounted to the head or not
Mounted but not active: Again RRF-3 can be coded to provide that info
Mounted and active: That information is ALREADY displayed by DWC, the DWC status box shows the status of the "probe" be it ZERO or (usually) 1000 and when activated the box around the number changes its numerical value and colour shows up in RED

I would actually propose a Fourth state "Docked" this would allow you to know if the shoe in its dock or not as it might be possible for it to be accidently "dropped" this would be the part that requires extra hardware , I would personally use an optical switch to detect when the shoe enters it's dock, and when in its dock the optical switch reports that fact back to the firmware.

And while I haven't actually looked I am fairly sure conditional g-code could be formulated to only allow the head to go and collect the shoe if the shoe is actually in its dock, that could also be expanded to include a routine that checks if the shoe has been actually been picked up or not .

Thanks for all the input on this. We will look at how different types of Z probes are dealt with in general as part of the config tool review which I hope to be aligned with the 3.5 firmware/software release.

I am locking the thread as its starting to get into more of an argument than a healthy discussion.
