Best Z Probe for Duet 3 Mini 5+

@zapta thanks for the compliment.
I do not know that extruder combination. I am happy to help, but lets not clog up the OP's thread.DM me or jump to our Discord channel https://discord.gg/jfnVrUx2uK and we can figure it out.

Thanks @sinned6915. I think I found it, in the Docs by Printer folded section here https://www.euclidprobe.com/02-probe-docks-toolboard-mounts/ . I may give it a try. People are seems to be happy in general with this approach.

@zapta its a knockoff 3d Touch made by RedRex whom seems to make good knockoffs. I was just interested in something better, more durable, can take more abuse than a sensitive BL TOuch or 3D TOuch for that matter so anyways yeah I will probably check out that EuclidProbe and see how that goes as it appears it has a good happy user base so I cant see anythimg wrong with giving it a go..... Thanks!

Ill be installing that Euclid Probe into my Anycubic Chiron that I converted to utilize Linear Rods NOT Rails as I feel that Rails are a bit too stiff plus I like how the Rods look. So I essnentially am building a Prusa'fied Chiron but I like to call it Chiron LRE or Chiron 3.0 lols cause i really is. The Chiron 2.0 I had built used an BTT SKR 1.4 Turbo of which I used to think was THE best board one could get tht is til I learned abut the Duet3d boards!!!!!!!

@zapta the last probe i used was an IR probe.
I tried everything- I laminated the 0.04 pei to a piece of black anodized aluminum sheet to imporve the reflectivity.
Ambient light scatter still threw it off.
Hence the developement of the Euclid Probe. -

It's a very elegant design. If you are the original developer of this concept, Chapeau!

@tecno, have you used IR with a PEI sheet (e.g. 1mm), if so, what was your experience?
I use PrimaCreator FlexPlate PEI and I usually have to baby step printhead down a bit.
Using backside to print PETG usually no babystep.No mechanical probes for me anymore as I have had my share of big problems with that shit.

After reading this thread I decided to replace the Z probe on my printer with a stowaway microswitch kind, so built a Voron Clicky Probe from a swtich and magnets I had and its seems to work quiet well. It is definitely simpler than the standard Voron V2.4 z stop + induction probe arrangement and it measure the actual top surface which I prefer. Also added gcode to the pick/drop macros to verify that the probe is actually picked/dropped as expected for extra safety.
What is a good way to quantify the accuracy or consistency of a probe?

with a zero/zero offset to the nozzle
Can you explain this? Do you mean X offset? Y offset? Z offset? Something else?

A lot of people use the CR-3D SupCRprobe... a temperature stabilized inductive sensor which works with extremely high repeat accuracy

here e.g. in the C1mini with Duet 3 Mini 5+

@zapta This is what I do:
M98 P"k/probe-attach.g" G1 X100 Y100 F18000 G30 G30 P0 X100 Y100 Z-9999 G30 P1 X100 Y100 Z-9999 G30 P2 X100 Y100 Z-9999 G30 P3 X100 Y100 Z-9999 G30 P4 X100 Y100 Z-9999 G30 P5 X100 Y100 Z-9999 G30 P6 X100 Y100 Z-9999 G30 P7 X100 Y100 Z-9999 G30 P8 X100 Y100 Z-9999 G30 P9 X100 Y100 Z-9999 S-1 M98 P"k/probe-detach.g"
If it isn't obvious, I too have a clicky probe (annex quickdraw in this case).

@engikeneer that's a really good idea, I should try that

attach/detach, I called it picked/drop
Thanks, will give it a try, including attach/detach between each probing.
BTW, I do homing, auth leveling and mesh probing with hot bed, since it can also impact the results.

My Euclid PCBs arrived today, in the UK.
Have everything ready apart from the magnets, unless I want to spend more on delivery than the magnets from USA.I have run BLT originals on my RailCore / Voron2.4 and Ender3.
The RailCore struggles with back right corner with a BLT, nothing wants to stick to that area! Always too high.Hoping the Euclid probe will alleviate that issue!

@pfn, I run 100 iterations of attach/probe/detach and got the message below
"G32 bed probe heights: -0.129, mean -0.129, deviation from mean 0.000"
Does it mean that I need to increase the Z value in my probe setting?
G31 K0 P500 X-2 Y19 Z9.1
Also, is there a way to get the 100 probing values or at least min and max?
echo "Home all" G28 while iterations < 100 ;echo "Probing " ^ {iterations} M98 P"/macros/clicky_pick" M98 P"/macros/z_current_low" M98 P"/macros/speed_probing" G30 P0 X127 Y106 Z-9999 M98 P"/macros/speed_printing" M98 P"/macros/z_current_high" M98 P"/macros/clicky_drop" ; --------------- echo "Last probing" M98 P"/macros/clicky_pick" M98 P"/macros/z_current_low" M98 P"/macros/speed_probing" G30 P9 X127 Y106 Z-9999 S-1 M98 P"/macros/speed_printing" M98 P"/macros/z_current_high" M98 P"/macros/clicky_drop" echo "Clicky test done"

The probe is not offset from the nozzle on either the X or Y planes, the switch is picked up from its dock and sits directly under the nozzle at a known distance below the nozzle hence Zero/Zero.
That's very neat. Thanks for the explanation. I thought that this is what you meant but didn't know how it can be designed.

@zapta your macro has a mistake it should be G30 P{iterations}
So you didn't get an aggregate result
The final G30 should be P100
Also, I'm a bit concerned, it says the probe result was 0.129mm lower than the homing probe. It could mean the mount is inconsistent.
With the correct P arguments, the result for G30 S-1 should list all probe values
