I was asked to try out an infrared ABL probe that I hadn't featured before, and compare it to popular ABL probes. In this video, I put the Aus3D IR Z probe, BLtouch, EZABL, superPINDA, Touch Mi and a miroswitch to the test to compare accuracy, pisces, ease of installation and more. The results are a big win for 3D printer owners overall.

Since I'm using metal magnetic build plates, I'm using inductive probes and these have been the absolute best for my personal setup. I've used a BLtouch, but it died prematurely. I've only had an inductive probe die on me once and I've used 7 so far. The underbed piezo sensor is at the second place for me, especially on the Delta printer. I enjoy using it a lot and it's very precise as well, but it's sensitive to oozing, causing premature triggers. So a clean nozzle tip is essential since you're using the tip of the nozzle to probe.

With a limit switch, you'd really not have much of an option but to use it as it's shown in the video -- magnetically attached only while probing, and then removed during printing.

Great design, just love it, new leds for visual inspecion, very easy to use (once you know what you are doing - unfortunatelly mine start was very tricky and long - and here is a moment what is included into price - good support of TH3D team!!!! Occasionally they are willing to talk on topic related with 3d printing (not only EZABL) and they have huge knowledge on different background. ) Buing EZABL you have to keep in mind that in some cases (printers) you'll have to gound all stteper motors (my case) and PSU, level your printer manually on begining as close as you can get. Yeap , standard div. test might be different on range of temp. Not a big deal while you use always one kind of filament. Sometimes it's required to turn off bed heater (like in AC Keenovo heaters- again my case:) Another great adventage is fact that TH3D provided theris Marlin version compatible with EZABl sensor.

I own and operate a small print farm (4 Artillery SWX1-v4) which have been modified using a fixed height (no springs) heated bed (Artillery glass), and BLTouch probes. All 4 printers are setup exactly the same, use the same firmware, and run at different intervals depending on print load. I have run this setup since August 2020, with no major malfunctions. I used to run an ABL every week at the start. Now, I run the mesh and store it around every 3 months or so. All beds are fixed to the Y axis plate, and deviate less than 0.01mm throughout heat cycles. I still probably run an ABL way more often than I need to, more for piece of mind than anything else. I don't see any deviation between print cycles, and the mesh tends to be very consistent throughout all machines. The only time I see a need to rerun the mesh cycle is when during seasonal transitions such as spring/summer, summer/fall, etc. The changes in ambient temperature and humidity, even with factory heated glass beds, tend to affect the ABL Mesh more than anything else. Since making the modifications to the printers, I consistently run at 100-140mm/sec speeds using the factory Titan Aero clone hotends and Volcano nozzles. Belt tension and v wheel tension is most important to stop ringing and ghosting, but are quite manageable.

I'm using microswitch from the Z axis endstop with allen key as a probe tip, which I manually deploy when leveling bed. Works very well, 0 cost as almost everything comes with the printer, you only need some long wire and print additional part to mount it. Never had problems with first layes. Leveling takes a while as my bed is so wrapped that I need to make 7x7 probing points, but I'm doing it not that often as the bed seem to hold it's place very well. Downsides - you need to deploy the allen key every time the printer is homing, but it's not that much of a deal. It probably could be configured to use Z endstop, which I mounted anyway in parallel so it doesn't crash into bed if I forgot to set allen key in place.
@urufushinjiro
@urufushinjiro 2 года назад
There needs to be a follow-up test, accuracy across probes at a single point at a single point in time is important, but as you see, there is so little difference it's a tossup. Where the different probes can actually make a big difference is in Z homing/Z offset between prints. A set temperature may still get ten probes with little to no deviation, but probe across ten different temperatures and you will have a different DISTANCE from the bed that the probe triggers (and I don't mean just the expansion of the bed, I mean a variation in nozzle height over the bed that the probe triggers at) making consistent 1st layers between different prints visa vi Z offset problematic.
@Kalvinjj
@Kalvinjj 2 года назад
Indeed, I've had something similar (not necessarily a problem on the probe, but could be) when printing different materials. PLA, ABS and PETG all seem to require different Z offsets to stick properly and not smear too much the 1st layer so it doesn't blob. What I ended up doing to compensate this, is find the best Z offset for one material, leave it there, and compensate on the 1st layer flow percentage. This way I just enable different profiles for different materials on the slicer, and all works without messing with the printer itself, not to mention not like some fraction of 0.2mm matters in the height accuracy anyway.

@pnt1035 2 года назад
If you calculate or even measure the difference in Z offset between, say 190C (the lowest you'd normally use for PLA) and 240C (the highest that would be safe with a PTFE-lined hotend) you'll find it's very small - in the same ballpark as the standard deviations. What certainly will make a difference is the amount of squish that's ideal for different filament types. It's well-known, for example, that PETG likes less than PLA, and that's what changing the Z offset is good for. If you have a decent slicer, you can set an extra Z offset there, which is what I've done for all my PETG profiles. The optimal amount is significantly bigger the standard deviations Michael measured, or that would be accounted for by thermal expansion.

I was surprised that the LED probe was so accurate. The angle of the LEDs causes the return signal to peak at a given distance, something I have seen in industrial controls. I don't think the brightness of the signal matters too much, just the peak. The electronics probably reacts to the percent change over time. The fact that there are two LEDs and two receivers also makes it more robust as the electronics will see the peak twice. I am a controls engineer and finding accurate sensors for cheap is very difficult. Most sensors have published accuracy or repeatability values in the millimeter range at best. Lately I've been searching for a sensor that can detect the distance of a plate of glass with an accuracy better than +/-0.1mm. Most optical sensor vendors don't want to touch it, saying glass is too difficult. There are a few that cost thousands of dollars and can always measure the thickness of the layers of glass. But I'm just looking for the distance between the robot and the glass. Of course I'm trying to make the measurement without moving anything or touching the glass, so that makes it more difficult. I'm currently looking at two ultrasonic sensors, both have a repeatability of +/-0.375mm, of course temperature is a factor because the change in air density. So what I mean by all this is that the optical sensor in this video is remarkable.

Being that the Hyper was built by little ol' me, I can't guarantee perfect squareness of the bed frame so having the option to adjust the bed was necessary. However, after lots of tweaking, i was able to get the bed leveled enough to have a beautiful first layer.

I've had the same issue too, I thought it was something within the body itself but it makes sense it'd be the pin. something that has helped in my case is fidgeting with the mount. Im not sure about the stock metal mount as im running the Hero Me Gen V and I made a custom mount for it since none were made, and with a little fidgeting of how tight the bracket is to the body and how tight the CRTouch is to the bracket, I've all but eliminated the vibration. I think it's the same case as your 3d printers feet, you need a good mix of dampening and elasticity and that should get rid of the vibrations.

I'd like to try one of the Clicky probes that everyones talking about, but I don't know where their popularity is coming from, whether its accuracy, or just the coolness of the printer picking it and, and putting it away at the end. I currently have BLTouch, but only because when I first started out, it was the first thing that I heard of, the idea of auto levelling was so new that as soon as I discovered one, I ordered it before even learning how they work, or how to install. I think the takeaway from this though, it really doesn't matter which one you use, they'll all work better than needed for FDM printing, so basically, go with which ever you already have, can get, can afford, or think looks the coolest.

Aw, you should've tested piezo sensors! I use a piezo setup now, and I'm so glad I switched to it from inductive bed leveling. It's way more accurate, and not having a probe offset is great. The only downside is that it's not really plug-and-play. It took some experimenting with mounts and configuration to get it all down (you need a mount that bends the disc to be the most accurate). Once you have it down, there's nothing more accurate.

I'm a bit disappointed you didnt test the Creality CR Touch. Others have reported it to be more accurate (technically). I was able to buy one on Amazon for cheaper than the BLTouch. The metal probe tip, more subtle lighting and modern design make it a better choice IMO. It also is plug and play (less a simple firmware flash on a 32 bit board) for huge population of Creality printers with the included metal brackets.
@joshuaanderson9079
@joshuaanderson9079 2 года назад
I use an inductive sensor (and raw analog hall effect sensors for my endstops). So while i love my inductive sensor for my cast aluminum bed with PEI sheet there are some draw backs that just aren't going to change. Number #1 is i can't make use of magnetic flex beds unless i carefully pick probe points that don't interact with their magnets. #2 Tilt matters, the field coming off the induction probes are typically two lobes (oblong spheres) which isn't labeled in any way. The detection pattern for most of the useful distance would plot in an oval or more like a peanut shape in 3d, which isn't an issue for their typical use (and why the detection object is usually specified as at least the diameter of the probe). This means the probes will be more sensitive to tilt in some arbitrary axis (well, where ever the center line between the two lobes is) compared to a corresponding perpendicular axis. #3 probe speed matters (much more than temperature until you probe real slow). This is the switching frequency or response time on a spec sheet and the probe will not necessarily switch state faster than this so any movement is unaccounted and increased speed reduces your precision. This variation probably won't show during testing until you go to print unlike temperature change testing if you do not have a dial indicator mounted alongside the probe to see it. (I need to mod a dial indicator with an inductive probe one day for an awesome quick and dirty probe for less effort than modding a $30 harbor freight digital probe or legit digital probe that costs more than many printers, feel free to beat me to it and share ;) ) Most inductive probes switch at 500hz until you you break the ~$60 retail price point for industrial sensor to get 1khz to 3 khz ( next price point is like ~$150+ and specs can get to 5khz). So the faster you're probing the larger the distance variation between trigger intervals. I use a M8 sized all metal probe , an ie5390 i grabbed off of ebay for like $30 and it operates at 1khz. I currently get under .005 mm bed leveling results on my delta running a duet wifi. For physical switchs, oddly the best repeatability I tested was actually a switch I pulled from a spare sanwa arcade button I had, much better than a limit switch although definitely not as rugged. It still makes me want to test cherry mechanical keyboard switches as probes, they have a precise trigger point for consistency and are designed for way more operations than I'd naturally probe without doing tests.
@filanfyretracker
@filanfyretracker Год назад
Prusas have no issues with a magnetic bed, so either the SuperPINDA is something immune to magnets. Or because they designed the whole thing, their leveling grid is simply laid out in the firmware so the probe never senses near a magnet. Speaking of magnets though, I have seen some magnetic beds that use a whole magnetic sheet, verses the singular rare earth magnets like a Prusa. I wonder if anybody has tried to exploit that and use a sensor like that from a home security system for doors and windows. those commonly just have a magnet on the door and a microswitch is pulled closed when the door is closed, or pulled open. Either way when the door is opened the switch state changes and the alarm goes off if armed, Makes me think that could be exploited for bed leveling in the magnetic sheet setup.

I am going to buy my first 3D printer this autumn (here in Sweden autumn is on it's way, would love to visit my Mum and Bro in Adelaide for a couple of months now 😂) My choice has fallen on the Prusa I3 MK3S+ with the MMU tho, so the probe is already a given. I saw a video where they thougt the BL Touch was very slow when calibrating compared to the EZABL but I'm sure other, more knowledgeable peeps, can confirm/deny it. It would have been interesting to see included in the tests, a comparison of calibration times and number of points. Time for calibration is significant if you calibrate before every print, even tho it may not be a long time in my life it can be frustrating to wait longer than needed. Like everything today, it isn't about the real wait/safety/health, it is about the perception of the attributes😁 Nevertheless it is interesting to see comparisons like this 👍

The post installed bl touch on my ender ran flawless until one fine day it decided to let drop the pin and crashed in the print. The reason must be a loosen contact for the magnetic coil which is lifting the pin. Since the standby position of the pin depends on power, it's a little risk on the Bltouch to ruin the print and the probe.

This was a review on the SuperPinda store page --- What they don't tell you about the SuperPINDA What they don't tell you about the SuperPINDA: As advertised the SuperPINDA as a higher quality, temperature-independent probe, compared to the PINDA. However, it has an important disadvantage compared to the [original] PINDA - slower bed meshing times. The higher quality of the SuperPINDA comes at a cost of slower speed. The FW setting for the SuperPINDA bed-levelling probing speed is at least two times slower than the same setting for the PINDA. Also, there is a delay in getting the SuperPINDA to a stable temperature level. The result is that mesh bed-levelling with the SuperPINDA takes a lot longer than with the [original] PINDA. 22 out of 25 people found this review useful.
@lukeswanson6887
@lukeswanson6887 11 месяцев назад
I've been using the CRTouch and it works great. It's basically just a fancier bltouch, but more or less works the same. The only differences are A. the probe is metal, and less prone to breaking, and B. the sensor it uses is more accurate and durable. Also it is a bit easier to install on a creality printer, but if you're not using one, there isn't much difference. Honestly, the only real benefit is not having to worry about the pin break, and I think the crtouch might be slightly smaller than the bltouch height wise. After using it for a while, I may eventually choose to switch to a beacon3d scanner, but with dual z and z tilt leveling on my printer, I can pretty much just use the same mesh over and over again without any problems on the first layer, and I only really probe it if I have to service the printer and somehow it changes the z offset or the bed position.
@woodwaker1
@woodwaker1 2 года назад
Very good analysis and review. I have gone with the Ezabl, the ease of use and support by TH3D was worth the cost. It is also very fast at probing which ids a big advantage to me since I do a 5x5 probe before every print. The accuracy and speed spread over 100s of prints is only a cent of so per print. I even replace the BL Touch that was stock on my Ender 5 Plus when the pin broke.

One of my printers came with an IR sensor (not the AUS3D, just a generic IR Prox sensor), and I found that the color of the bed or print surface caused distance variations and would cause the print to fail on the first layer).. I discovered this when I had to replace the factory black print surface and got a "name brand" with fancy graphics and color and the printer basically either started printing in the air or dug it's nozzle into the printbed. Blue painters tape also caused the sensor to see yet another distance.. I tried everything to fix the thing but because it had an R-Pi with a customized Octoprint as an intermediate controller for its touch screen, it was a pain to mess with its firmware and I eventually just gave up on the printer...
@Hoovie59
@Hoovie59 2 года назад
As mentioned below, I find that temperature does not affect standard deviation but it does change the distance that the probe triggers at. This make swapping between printing PETG and PC a little more tricky since you need to have a separate Z offset value. In my case I noticed the super pinda detects sooner at a higher bed temp.

I had no doubt all would be more than accurate enough, but i think you missed some key things: 1.) Probing across the bed instead of just doing probe accuracy in the same spot, since bed temperature and topography varies based on coordinate position. This also affects point 2. 2.) The quality of the sensors and their wiring/electronics, sensors with cheap wiring etc could have significant emi issues that effect them, ive seen it many times with BLTouch users since it has no shielding on the cables at all. Doing probe testing with all the steppers and fans etc on would be more accurate of a test for this point and #1. 3.) Overview of overall firmware setup and installation for each probe. 4.) Support, in terms of mounts for specific hotends/printers etc.
