Euclid probe: Light, robust, mechanical ABL for your 3D printer

- I like trying new ABL probes, and in this video I test the Euclid probe. It is unique in that it comes in two halves. One stays attached to the print head and the other is only added for probing, which minimises moving mass. Being a mechanical probe, it is suitable for any bed surface and the high quality components make it suitable for heated enclosures too.
This video tests the repeatability and shows assembly and installation on two different printers.
This product was supplied free of charge for evaluation after Euclid agreed to my review policy. All opinions expressed are my own.

I've been using a Klicky for a few months now and it was a huge quality of life improvement. Switching between removable bed types is no problem, regardless of the material.
Very nice and simple probe, they made some smart choices to prevent issues
I've been using it on my voron, after tuning, its extremely reliable and I've had no issues with false pickups, ideal mount for the voron 2.4 is bed mounting and with auto z calibration, it's really dead simple to use. If mounting to the bed, then a few steps are needed to dock it -- after homing and doing quad leveling, i home z again to establish relative z 0, this ensures that the probe can be safely docked. Then do the auto z calibration, and mesh if desired. If mounting to the gantry, there is no need for extra home z, but it's a bit more risky since the probe can be possibly picked up in odd printing motion, but even in that scenario, the motion is very specific, so it's extremely unlikely in either mounting setup.
I’ve been using the Euclid probe on my Railcore 300ZL for 8 months now. I’m very happy with it. The Railcore MIC 6 bed has very strong magnets and it can mess up readings from the BLTouch. This is one of the strongest arguments for a probe like the Euclid.
The CRTouch has optical triggering,, btw. The electromagnet is just for releasing and stowing the probe.
@@Bubu567 I had a CR-Touch which was working great until it decided to drop the probe mid-print resulting in a permanently bent probe which makes it useless as it's not replaceable. Luckily it was still under warranty. I loved the quality and accuracy but won't be buying another.
i hope every day that there is the all problems solving true nozzle probing solution, eventually the community can adopt the prusa xl way that seems to be the best solution we have for now. Besides that a great video and nice to see that the progress is going on 🙂 personally i always come back to my bltouch no matter what i tried in past 😅
Looks like a nice simple and reliable design 8-)
Great video, but it is all in the printers. I time to time test my leveling and find it every time spot on. Loving my QIDI :)
Nice.. was gonna skip the Omron sensor on my Trident build and go with this. Great timing for your video.
This literally uses an Omron switch? huh.
Euclid for me, is making up 1 half of my auto z calibration. At print start, i heat my bed, and my nozzle, making sure to deal with any ooze through a nozzle scrubber. The nozzle itself homes to my z endstop. The probe then homes the shoulder of the microswitch to the same endstop, and the bed. This means, all you have to tune is the offset between shoulder and trigger point of the euclid microswitch. Any changes in build surface, nozzle or temperature, are all accounted for. I honestly think this is 1 big step in useability that makes 3d printers much more friendly for the common users. Id love to see it done on a commercial printer.
The Mclaren Papaya orange looks great on that grey. I want that sweatshirt lol, you always have the best F1 jackets.
Recently moved from BLTouch to Euclid. Very happy with it.
Looks like a great addition to the probes :)
I would love to see you test the Orion probe from presicionpiezo
I've asked this as well!
I read through these comments and I can't help but laugh at how genuinely *upset* some BLTouch fans seem to be over the prospect of others preferring something like the Euclid Probe... Y'all are making my day
It’s strange how a 3D printer part or firmware can bring up such strong emotions. Maybe other hardships in life reflected to a hobby
@@apinakapinastorba I think you might be on to something
that's a very interesting way to cast our discussions in another comment thread. sadly it is wrong.
since this is very obviously talking about me, let me clarify: i don't care what you prefer, and i am not a "fan" of the bltouch. i was talking about the merits of the Euclid Probe compared to existing solutions like the BLTouch. and as far as i can gather, the Euclid doesn't have any proven merits over existing solutions. i won't repeat my arguments here; i've covered them all exhaustively already.
lastly, characterizing me as being "upset" is disingenuous. if anything, i find it amusing that you're so willing to argue in circles about a topic that you are thoroughly beaten on.
feel free to continue justifying your purchase of the Euclid Probe. maybe you'll generate enough positive exposure that they can make a more compelling product. I just hope they're at least paying you.
@@tehmoriz This is great! Alexa, play "You're So Vain" by Carly Simon!
@@tehmoriz There's a psychological term for people who think everything is about them...
Played with allot of stuff like this in the past. Magnetic pen tool changer with 5 colours . Brush nozzle cleaner etc and think it looks cool but for abl I prefer to just keep it simple, with a bltouch or a conductive sensor . The pickup designs I used would eventually fail in my case or slightly crash the partcooling or the slightly unaligned thing itself. Love how innovativ people are though
Hi teaching tech ! I notice you have talked about klipper. Your channel is the one that taught me the most about setting up my printer. I have made the move to klipper and I have trouble with some thing. Would you agree to make tutorials about klipper ? I am struggling with maccros, and organizing file ( as i have seen you have a homeall.g, i don't know what it is for, and how to call it), I am having big trouble setting up my tplink, just like I did in octoprint and stuff like that. Also, my mesh calibrate isn't working as intended at all...
THanks a lot for all your video, you have truly taught me a lot about 3d printing !
Interesting! I have an Anycubic Chiron freshly converted with a BTT SKR2 + RepRap, and I have a issue with the bedleveling. The probe must be installed/removed manually. I use Z endstops on each of my Z motors for gantry level, and a probe for bedleveling. But RepRap don't like that when you try to load your mesh leveling and warns you the Z=0 datum is not set properly. Most solutions I could find are "just put a permanent BLtouch" but this is a great alternative.
Hi Michael! would you consider making a video about input shaping on RepRap Firmware?
this is exactly what i was looking for! how is the accuracy/repeatability when used in the heated chamber?
Could you please test the accuracy of sensorless probing with the newer stepper drivers?
one thing you didnt mention but is a thing: temperature drift... i had an inductive probe that had great repeatability (standard deviation of 0.006), even at different temperatures. BUT: when i set the Z-Offset with ABS temps it worked as long as i printed ABS... when i switched to PLA the nozzle touched the bed, stalling the extruder, and on a cold bed it outright rammed into my build surface... so would strongly recommend testing this aswell...
I set my Z-Offset on a per-material basis in my slicer.
If the probing is done with already heated bed, I’d assume there is no problem with a mechanical probe. I wonder if the assumption is correct
@@apinakapinastorba I have an Ender 5 with a CRTouch. I probe before every print after heating the bed and the same z offset works for both PLA at 60C and ABS at 100C
@@Miraak15 I have a deviation of .06 between 60c and 100c, but I'm also using a much larger bed
@@jfaristide that would be one way around it, but another factor comes in here: preheating time. If i heatsoak my enclosure for print that would otherwise warp, the offset is off again. (The warmer the Probe, the higher the trigger distance)
But all of that is now fixed since I installed a superpinda
Love the McLaren hoodie!
Hello
does the holder for the Super racer also work on the flsun q5 witout any modifications ?
I'm currently running a modified Poor Man's BLTouch micro-servo + optical endstop probe which outperformed the 3D-Touch that came with my Sapphire Plus by a factor of 10 in accuracy. However, I have been looking at the Clicky Probe, but have the problem that my print-head cannot move outside the print area. Hence I'm considering having a Clicky Probe dock that can be put over the print area using a servo. Would make things again somewhat more complex to dock/undock, but would still allow getting the weight off the print-head. As for the probe you reviewed: $25 seems a bit much for what you are actually getting, no?
Compared to a Klicky probe it's pretty expensive, but compared to a BLTouch it's very cheap.
Looking at your stow/deploy macros, it looks like the deploy is state-dependent and hence failure-prone. Run that deploy macro with the probe in place, and the probe will either fall into the bottom of the printer or stick randomly to something on the print head.
Would it be safer to deploy by running the stow moves first? Especially if you're remote-starting jobs, you can't be 100% certain of the probe state, and for the sake of two extra moves it seems like it would add peace of mind.
(Running stow with the probe already stowed would appear to have no consequences.)
Hello great tutorial, I have a question about Ender 5, if I attach the display to the frame, pip the display and automatically jump to the menu and back, the mianboard is new silent 4.2.7
what can it be and how can I fix it because I currently have the display on the table?
I just installed one of these. Best bed probe you can possibly get.
If I go with a bigger nut size nozzle will it perform better I know they start at 6 mm and go all the way up to 10 mm just wondering if the bigger ones are better
As you just finished with the SK-Tank, I would be curious about using this ABL instead of the inductive sensor. I've had no luck with my SK tank bed leveling even though the size and mass of the bed would suggest otherwise. After I mapped the bed for the first time (preheat and post heat) you would have thought I was trying to print on a bell. Adjusting the inductive sensor height including the little lock nut is darn near impossible with my chubby fingers. I was thinking of going to BLTouch but I would prefer something small and removable like the Euclid. Any interest?
I gave up on inductive sensors a while ago. They are completely unreliable. If the bed was made of iron it might be perfect, but anything else is just luck.
Nice! Wonder how that would compare to one of the other "DIY" solutions like FreeABL
Man being just a hobbiest amd picking up the printer when i need something ive run into issues with things changing and as well as breaking after coming back to it. I like this idea for bed leveling out of most and want to try it. But i have an issue where i dug deep into teaching myself how to compile firmware by watching your vidoes and by the time i wrote the firmware for my first skr mini e3 v2.0 i did the furmware myself and did a bunch of differnt touches that i learned from your channel. But fast forward about a year and i burned up that skr mini e3 and didnt save the old firmware i made so id have to redo it. I found it extremely harder to figure out as im guessing updates to programs seemed different or i just dont remember right. Im a auto mechanic by trade and dont always have use for 3d printing but when i do it seems to come allot. Im worried about doing a firmware for this then forgeting how to do it again. How would you suggest someone like me be able to do this say after a uear of doing it the firat time. Or am i just showing how little i know about computers and programming that i forget it easy when trying to teach myself something that i womt use constantly. Thank you for all the great knowledge
Marlin now have a option for magnetically mounted probes .please review
How about using a metal bed, and using a conductive touch probe, something like the luzbot use? They attach a wire to the extruder, and the nozzle touched the bed corners where a second wire is connected, it closes a circuit, and then you don't even need to connect a probe, just an extra wire.
I am soon to receive my VCore 3. And I intend to use the euclid at some future point.
Would be nice to have a vid, explaining how to and what I need to change in firmware.
In the mean time I will be looking at the Vcore Git, for any files pertaining to the probe
There are a number of example VCoreOS files in the git repo for your use.
Received my Probe, must have got lucky. Didn't just get the kit for the probe, but got the fully assembled probe, with kit as spare bits.
Only found this after printing the jig ready to assemble prior to receiving
Pleasantly surprised
@@UKCM please contact your reseller. I am sure they will want to know of their goof. Enjoy your Euclid Prode!
Would it be possible to set this up on in Marlin as follows?:
1: Don't allow homing if probe is not connected (wait for user to attach probe if nessecary)
2: Once probe is connected, home, bed level, etc.
3: store probe, and print
4: at completion of print pick up probe again. This way the probe is already in position and even if you shutoff the machine and lose home when you turn it back on it's ready to rehome without user intervention.
You can't print with the probe attached to the print head, that's the whole point of making it detachable. A mechanical probe needs to be lower than the nozzle in order to touch and probe the bed.
That's why the BLTouch retracts it's probing pin.
So after we setup the probe, we then setup Auto Bed levelling like usual??
Hello, I have creality ender 3max it will not print the product dont know what else to do I levelled bed with sheet of paper still wpnt print any ideas,
And if for some reason it fail to dock the probe? what's appening hotend crash to bed? is there anysystem to check if probe is attached? to prevent dock fail and bed crash?
Rocking that new McLaren merch it looks, let’s go!
Can it be added to the Aldi Cocoon Create printer?
If induction probe can't work for your bed type, this looks like the next best option. For farm tough, would really want induction probe. Personally, wouldn't touch the BLTouch with a 10' probe.
Could you review the open source Pyroball piezo-based ABL solution?
Pyroball has ceased operations, sadly.
For i3 style printer, does the parking position get mounted to the frame or the bed?
The dock gets mounted to the bed carrier. You need two degrees of motion to dock and swipe.
Just question i guess not going ever finish mobility scooter its been 3 years ?
Do you probe with cold or heated bed?
Probe with a hot bed. as it heats the bed will experience thermal expansion so you will want to do it hot
Nice idea; If I understand correctly, for a printer like an Ender 3, you will still need a way to home Z, correct? Unlike other probes like the BLTouch or inductive ones, you can't use the Euclide probe as an endstop.
You can. But I wouldn't. I have an Euclid on my ender 5 pro and I'm very glad I still have a z endstop because accidents do happen (user error on my part)
@@emielv7677 But the Ender 5 pro has a moving bed (Z Axis) so the X and Y axis remain all the time at the same height, so you can easily go and grab the probe (no matter where is the bed as long as it is not at nozzle height) i.e., the nozzle moves in the XY plane. In an Ender 3 or Prusa MK3 type the nozzle moves along the XZ Plane, you would first need to home Z to know how high is the X Axis and go grab the Probe, am I right? or there is something I am missing.
@@sebastiansombra you need to home all axis' before you can move an axis. (Unless you use the force move command but I didn't use that for safety reasons)
@@sebastiansombra you can see a video of the entire probing procedure on my CZcams channel
@@emielv7677 Right, maybe not completely safe, but in a strict sense you could Home X and Y and go grab the probe to home Z (maybe lowering the bed a bit to avoid collisions), i.e., use the Euclid probe as an endstop. In an ender 3 you can't do that.
How is this any better than a normal BLtouch?
Looks very cool. But it looks too complicated for me to setup. I am Tech savy, but it still looks like a lot to do.
Love it!!!
Very unique system. I like the whole docking system. Interesting take on abl!
I’ve completely moved away from abl probes. Just personally hate them. They add an unnecessary complication to a problem that I can easily and more cheaply resolve with a cheap piece of glass from the hardware store. This is my own personal belief, if abl works for you then fantastic!! Not saying abl for everyone is a waste.
But with that said. The auto docking feature is pretty damn cool. I could see using this on something like my flsun delta printer that doesn’t have a glass bed and uses a manually removable abl type system.
It's very satisfying to watch. I think I have a video of it docking and undocking on my CZcams channel
I went from a BLTouch to this and will never go back.
Something can't be very unique. Nor is this actually unique.
@@jonatanrullman oh please. This was entirely from a personal perspective. As such I I made sure my comment was clear about this.
I (me personally, my own opinion) found this to be HIGHLY unique as it is something I haven’t seen. There for making it unique to me. Better?
Semantics dude, come on.
BLTouch vs Euclid probe!?! Didn't y'all look at the std deviations in the video? The WORST probe he tested had an insignificant deviation. You will have no issues with either probe--get the one available to you or tickles your mod bug the most.
Friend of mine met the creator of Euclid at MRRF this year... said he was very opinionated and a bit of a jerk, spoke very dismissively of Klicky as "stealing his idea" and tried to sell my friend a Euclid kit for twice the normal price... 🤨
Is the electrical current passing through the magnets? If so, I guess its not much to be concerned .
There is no active current through the magnets. Your controller sees the switch as continuous, complete circuit that gets broken when the switch is triggered.
@@euclidprobe Don't get me wrong, since it is your product... but the electrical connection between the two parts of the probe is via the magnets as far as I understand. There are no additional pins or so that must align when coupling the two parts. Only the magnets that touch each other, and therefor, at some point, a current is running through the magnets.
@@McOldwolf it takes practically no current to light an led. A good bit to run a stepper motor. It's only enough current for the system to determine if this pin has voltage or not.
What happens when you get a bit of swarf on one of the magnets? Wouldn't it be better to have the mating parts be some hard-ish (e.g. aluminium alloy, brass, etc) balls/pins for kinematic location and then the magnets coming close, but not touching, for the fixing?
been using my euclid for months with zero issues like that
You got swarf in your printer?
If you have a problem with swarf in your printer, ABL should be the least of your concerns
@@ohiohouston3560 Could be he's using one of those all in one printers? But yeah, getting swarf on your printer would mean you got bigger problems lol
@@Albertotron In my opinion, using one of those all in one printers is a bigger problem.
Hmm....i get the idea that this type of sensor with a switch is not as good as for example the BL sensor which is mounted on the Genius Pro. What I do like: this one doesn't break and that's what happened to me when the BL sensor hits the print.
Well, that's not true. Omron switches are extremely accurate. They are more accurate than your stepper motors, so there is no way a BLTouch is more accurate than a Omron switch based probe.
@@Akegata42 but then you can ask yourself why do they made it more difficult/expensive than necessary.
Practical video, thank you Michael, you're not Micheal Obama but you're always a loved member of the vampire family ❤️
That included 3d printed part is as rough as a bears arse, I know its only a jig but its not a great advert for the product, I hope the quality of the electronics are not as bad
The printed parts are not included. You have to print them yourself
@@Runenaldo So it was Micheal who printed that dual colour abomination
@@AndrewAHayes No that was from Euclid
@@AndrewAHayes That dual color magnet holder has been deprecated. See the docs- the new one is labeled N & S and better suited for assembly.
How do we get in touch with Micheal if we would like to see if he can have a look at a printer for me? It has a fault we can not sort out, it can print benches, test cubes, heat test shapes, and pass all these tests - but anything large than that will not print and the head just starts hitting the side of the printer bed after a few passes.

They shouldn't be called ABL, they should be called ABLDFBCCP.
Auto-bed-level-deviation-from-bed-center-compensator-probe.
it's neat, but honestly feels like a solution in search of a problem. you're basically just shaving off about 5g of mass (and about $10) from a standard bltouch, and it probably won't make any difference in print quality.
It’s much more accurate than bltouch, not impacted by bed magnets, works at high temp, faster and isn’t finicky.
@@wesc23 it's not more accurate enough to be meaningful. the difference, as shown by Michael in this video, is some tiny fraction of the width of a human hair; not enough to affect anything.
i won't comment on bed magnets and high temperatures, but i've never encountered any issues with mine.
as for finicky: this Euclid probe literally mounts and dismounts itself on use. the amount of failure points is much higher as a result. as such, the Euclid is significantly more finicky based on that alone.
feel free to use this probe if you want, but it certainly isn't better than a bltouch in any objective sense.
An open air printer isnt a good use case for this probe. Starts to make more sense in a high temp enclosed chamber
@@tehmoriz anyone who prints at high temps will have stories for you that tell of catastrophic bltouch failures.
Over 4 or so years, BLTouch glitches and failures have cost me upwards of $500 in print surfaces, heat breaks, nozzles and probes. No more. After switching to the Euclid, I've no intention of ever going back.
@@tehmoriz I don't know, my bltouch has proven to be very finicky for the last month or two. A lot of false triggers before it hits the bed resulting in a wildly errant bed compensation and, if I don't notice it in time, failed prints.
I think the BL touch has just as many failure points, they're just not visible or accessible to the end user.
This looks more reliable than the BLTouch. I've had to replace the pin on my BLTouch once because I rammed it laterally against the bed bending it which resulted in a number of issues with it's deployment.
The magnets will chip with use. Snapping them together is pure death. They should bury them behind something. Even adding a washer to the magnet faces would be a good start.
Purely theoretical complaint. Doesn’t happen in practice over thousands of mate unmate cyclea
Hypothesis or experience?
@@condorman6293 experience
@@condorman6293 Experience. i'm well over 6k on my unheated probe, 4k on my voron, works great, no chips.
I've been using my Euclid for months now with zero issues (got it from Luke's Laboratory). The magnets seem to be pretty good quality
This really should come pre assembled imo. Sure its cheaper than the other probes but when you factor in the time to assemble etc it becomes less attractive.
Most resellers offer assembly services if you need.
Note: Your accuracy on microswitches will degrade over time.

Dang man, 25$ for a switch, a jst header, a couple of magnets and a couple of pcbs is steep, specially when it doesn't even come soldered and the pcb isn't even cut well... It's smart but not particularly innovative
I'm using BL Touch replica + plain glass bed for more than 2 years with 0 problems. This is a overkill solution for easy problem.
Nice ad by the way...
Yikes, bud. You've had zero issues with your fake BLTouch but A LOT of people had. Maybe they would appreciate an alternate option just like this. Just because you don't need this does not mean others won't. He was not even paid for this video which makes it NOT an ad. Next time, refrain from commenting a useless thought you could of kept in your head. Thanks
Also, there are motherboards "old style" like my Creality 1.1.3 that require some modifications (like cutting 1 wire from the display cable) to get an ABL working. in this case, you can use the microswitch as a probe and z endstop.
that doesn't require any modification since the z-endstop is default on any board.
so.... no, it's not an overkill solution. maybe it's pricey but even if I gather all the components (magnets, connectors, switch) I'd miss the PCB part, that I have absolutely no idea where to get it.
so to me it's a valid option
@@Crafter318 nice to meet you fan boi. Now go to shopping web site and but this pricey overkill thing. Mental.
@@federico9292 you should go for 32 bit boards for future proofing that device. Buy what ever probe you like, then take notes about your fine adjusments... Cheerrs
@@federico9292 Initial development for Euclid was done an 8 bit Melzi, basically the same. You've actually got 2 pins available on that 1.1.3 board
Lol, because of the assembly work this is definitely not the cheapest probe. Time is money. I guess maybe not for you.
I can't imagine this taking more than 5 minutes to put together
The BLTouch also needs to be assembled..?
The arguments people have against this probe are so weird.
I have several printers. They look different and have different capabilities, which makes different probes the better options for different printers.
No probe is perfect in every situation, but I can tell from experience that the Klicky probe is a hell of a lot more reliable than BLTouch, and takes less time in the long run since it will never catastrophically break and force you to buy and reinstall a new one.
I have not used an euclidic probe, but is has the same functions as a Klicky.
You could probably have installed an euclidic probe to your printer in the time it took you to watch this video, so I think maybe you should reconsider how you spend your time-money.
After building 2 of these for my RatRig both after a very short time (5-6 prints - bed mesh) the switch becomes highly inaccurate to the point its no longer reliable and the mesh fails. I've tried 2 switch manufactures for the micro switch. When I put the second (bottom part) on it worked for a while then started to produce "Probe samples exceed tolerance. Retrying..." to the point of failure.
I tired slowing down the probe speed but nothing works.
Anyone else have these issues? I don't want to go back to the BL Touch!!
