That’s amazing news!

I cant wait for the cartographer tap to come out. Richard has done amazing things at such an affordable price. Makes me wonder why beacon is so utterly expensive. Mine's worked flawlessly for 6+ months.

@@YourBuddyDinec richard didn't spend any money on rnd

Got a link to this "announcement"?

Nice!

How did you get it?

very simple. Just do an upgrade and follow the doc how to modify your config. Takes some time, you have f.x. also to upgrade tthe firmware of your beacon. But when you are finished its very impressive. Super new functionality for zero coins. Great customer service !!!

@@valent_t It's a regular Beacon with their new firmware downloadable from their site as of a few days ago.

How does that work, though? As someone who changes nozzle sizes relatively often - and has observed a difference of over half a mm in nozzle length between different sizes and brands - anything relying on a statically-set nozzle Z offset just isn't going to work for me.

That’s fair and totally true - spring steel sheets have become somewhat ubiquitous.

@@ygk3d One point I did not mention to keep it brief: how much resolution on the mesh you need is also influenced by the type of print surface. On my Ratrig V-Core 3 500 I tried even pretty high mesh resolutions with different surfaces. It seems that if you forget some tiny debris on the magnetic sticker and put the standard spring steel over it you get a hill in that place that can screw up your first layer if no probe point is near. But you put 1.5mm thick G10 with a metalic sticker on the bottom onto the same debris on the same magnet and the hill may have similar height but it is so gradual the neighboring probe points make the mesh relfect the real shape of the surface well enough to have no issues with the first layer. I use 10x10 when printing 450x450 mm or bigger and with the adaptive meshing algorithm this ends up being 3x3 mesh for any small print. With lifting the Euclid only 2mm after probing and 10k travel accelleration the probing is done in a few seconds. So this makes it hard for me to see how the faster scanning instead of probing would be a benefit even if it worked on G10 surface. Either it saves me few seconds on an hour long print or it gets me higher mesh resolution that does not reveal anything new. I can absolutely see a scanner like the Eddy being much better than for example BLTouch that is quite slow with the pin deployment needed twice or more at every probe point. Compared to that it will be both faster and have better resolution.

@@hebijirik great perspective. Thanks for sharing. The use of adaptive meshing definitely makes a big difference. Really interesting about spring steel versus G10. You find the G10 has good adhesion and release for most materials?

Based on the beacon contact demo, it seems the contact/tap implementation would work at enough distance through the G10, so perhaps for those surfaces you still do nozzle probing?

@@ygk3d The G10 is absolutely excelent for PETG which I print very often. Unlike PEI powder coated surfaces there seems to be zero deterioration after any amount of printing. I once scratched it accidentally so I tried an orbital sander on it, cleaned and washed all the dust from the sanding and it was like new again. Still sticks like crazy while hot and releases easily when cooled down. For PLA you need to degrease and clean it well, even fingerprints can decrease the adhesion too much. I would say it it slightly less bed adhesion for PLA than the PEI surfaces. But still very usable. When the plate cools down the PLA prints just completely release on their own. ASA/ABS is adhering a bit better than PLA but not as much as PETG. I decided to try the Vision Miner Nanopolymer adhesive on it and it works great too. It removes the PLA sensitivity to having it perfectly clean and freshly degreased. Prints other than PETG still completely detach once cold and the surface is still smooth. I like the low cost (I got 4 500x500 for less than the cost of just 1 PEI sheet), the ability to easily fix up slight damage and the option to buy different thickness based on how stiff I need it for the size. I use 1.5mm on my 500mm V-Core but it felt too stiff for smaller printers. I tried 1mm thick for a Prusa MK4 and a 200mm V-Core and they work nicely. Disadvantages are: the glass smooth bottom side of the print might not suit every part, so I still use powder coated PEI when I need that look. If your printer has magnets for metalic beds you can put a metalic sticker (used to make a magnet-holding whiteboard on any surface) but then you only get to use one side of the G10. Or you have to mess around with some other way to clamp it to your bed. Depending on where you are buying it might be easy or not - I emailed some local company that makes custom insulation for electric instalations and they sell it in 1050x1025 pieces in any thickness and they can cut it to smaller pieces of dimensions I ask for. So I got it quarted for the 500 and I got 16 pcs for MK4 🙂.

Exactly my thought. And about beacon - same, right?

@@vim55k yep, same

How thick is pei? Honestly pissing into the wind. It works flawlessly on pei.

We went to klicky probes from inductive not because PEI coating is uneven. It's because the z-offset has to change anytime you change build plate and that is annoying. A good PEI build plate has a very consistent thickness across its surface. beacon and probably eventually all eddy sensors are now also touch probes. The new beacon software allows it to detect when the nozzle hits the bed with around 50 grams of force and klipper is eventually going to support this natively for other eddy sensors. This means the probe can now compensate for the thickness of a build plate on top of the bed while also giving automatic z-offset calibration. This only needs to be done for the initial bed leveling and z-homing, as any quality build plate that goes on top of the bed will vary by less than a fraction of a single layer height in its thickness. The bed should be the only thing varying by an amount significant enough to effect initial layer quality. Thus for the actual slow part the, bed mesh, the eddy sensor is used as normal and thus saves time. Also the increased accuracy from the denser mesh means that the build plate can vary more in its thickness before it could sum to a great enough deviance to cause a problem with initial layers. Also LiDAR actually struggles with textured PEI plates, because it picks up the texture rather than the average thickness of the plate which is what you actually want. This is why bambu printers for instance turn LIDAR off by default on textured PEI.

I use a glass plate and the cartograph works just fine, its only kinda useless as the glas plate is quite flat. But this is just my experience

I would also love to see a CAN bus upgrade to the 2.4!

Interesting. It seems good in combination with Tap or an endstop pin. I haven’t used it for homing so can’t speak to how repeatable the z offset is.

Good stuff! Impressive that you didn’t need to baby step whatsoever.

@@ygk3d very impressive this is the first time in 5 years of 3d printing on multiple printers I couldn’t believe it either.

I wondering same. My old prusa mk3 got proxmity sensonsor build in allready. 😂

Thank you!

Thank you very much! Glad to hear.

I saw on the discord for it that they are supposedly adding a tap feature like the contact one as well. Has worked perfectly for me for like 6+ months now even at 105c beds for abs

Ya, I can't wait for tap support on my carto. It's made my k1 max so much better!

The BigTreeTech Eddy is currently not supported in mainline klipper yet, unless you wanna use Big tree techs fork( no one would want to). So they leave it up to the klipper developers to finish there product, unlike beacon or Cartographer3D that develop and support there products before and after releasing them.

Good tip!

Me too, I ordered my USB version two weeks ago, but they've yet to ship it, hmph!

that would be a good argument if it was anywhere near the level of accuracy and repeatability....it isnt. beacon can hit sub micron. and you cant do a 10,000+ pt bed mesh in 1 minute with a nozzle probe but you sure can on a beacon. running a 9x9 klicky on a 350 takes flipping forever and thats only 81 pt. i have a lot of printers (~25) and have tried just about everything. for example, on my newest printers (magneto x) my magneto for example has a nozzle load cell, but its only 0.05mm accurate- this is like 50x less accurate than beacon, i dont care if it can nozzle probe, it takes like 20 minutes to probe and the values are nonsense.

Beacon contact is out already (filming must have been done a while ago). Contact literally >just works

@@Bogm8 lol had no clue it was already out

Not to mention that as your nozzle wears it decreases in length - tap probe homing corrects for this by itself. There's a reason both Prusa and Bambu Lab are almost exclusively using tap homing.

No. I used the USB version of Eddy on the Troodon.

Max operating temperature too, beacon clears all

its not really a versus in my opinion. for cheap printers, go with eddy usb. for something like a voron i would go for a can board + tap/klicky + eddy coil. slightly more expensive than beacon all together and much more functionality and only one cable

@@KilianGosewischtap is quite possibly the worst thing you can put on a voron, it cuts accel performance in half and brings it down to ender level resonance response. and tap with revo is the equivalent of swapping a lawnmower engine into a lambo. this is one of the many many many many advantages of beacon over tap, not having the extra rail axis, weight, etc. canbus also has a slew of issues compared to usb and other bus systems like ethercat, but thats a whole other thing.

Thank you!

If you keep watching you’ll find out 😉

Might be worthy of a follow up video!

If you ever use a glass or garolite bed you will waiting tens of centuries. Besides, who needs resolution in tens of nanometers?

I’m using Tap, so no mounting position for a probe.

@@ygk3d I gotcha. That's why I went with the USB Eddy, to do the Z homing. I had to widen the wiring channel a little with my dremel, but it fits! Tap looks like a nice light/strong mount.

@@ygk3d ...also, I should have watched 100% before commenting. Doh! LOL

I don’t own that printer unfortunately.

BTT certainly has some ground to make up in the manuals department and explaining what products are compatible with which products. But over all for me? The stuff works pretty good. I had issues with an HDMI screen and they asked for some very simple tests to be done then sent a replacement. Both my voron's run m8pv2's and CB1's CANbus toolhead boards. Ones at 2k hours ones at 1k. I think they just released a new manta, or maybe it was a CB?, that supports SP1. I don't think the older models did. I could be wrong on that but pretty sure I seen it in a recent tradeshow video on Nero's channel. Hoping next gen of m8p's have the SKSM's built in because this whole data corruption on powerloss is a huge oversight for bother Klipper and Control boards. Save a lot of people a lot of time.

Interesting. Thanks for clarifying.

+1 Mark's BD Sensor works great ... I think it's a much better solution than Beacon or Eddy

As long as it runs Klipper and has a metallic bed it should work.

That would be an interesting concept

Beacon is all about that reliability. After talking yo the creator you could have metal parts in the keep out but it'd impact performance and as such he advises against it so you can reproduce the results Beacon is showing on other machines

Thanks. I’ll look into that.

Thanks. I’ll look into that.

I purchased from their site and had a fine experience.

😂

Doesn't seem to have its own mcu (eddy coil). Eddy usb and can have a rp2040 you have to define as separate mcu

Good question. I’m not super familiar with processors and their specs but I’ll take your word for it that the RP2040 is overkill. I guess they’re cheap enough that it doesn’t matter.

Maybe because it's easier to manage inventory? BTT has a lot of products all using the same rp2040 chip.

Klipper has RP2040 support already as a generic controller, and the chips are very cheap. Never know what all you can truly add in the future with onboard processing for very little cost. My personal mainboards that I design are all RP2040 for similar reason, even if it's "overkill".

just watch the video dude

Pay attention

I have seen someone who got the cartographer probe installed on theirs so you might be able to. It would have to be the USB model of course. It will depend on getting BTT's version of klipper on the mainboard and toolhead boards. I think that might be difficult though because I believe the cartographer install for the K1 relies on using a custom install script just to get vanilla klipper on the K1. Maybe when the Eddy is merged into vanilla klipper it will work.

Yes, I've already seen it. A user in the Devil Designs Discord has it working well. They combined btt repo with official +config.

I’d demand a refund if I were you 😂

Same. Not sure what wizardry that is.

@@ygk3d maybe some sort of measurement of the used current of the z-motors, when it touches something the used current would be higher so by firmware it says stop I'm touching something. Like sensorless homing works.. Maybe.... 🤷 Only that the nozzle touches any surface in this case...

The probe can detect when the magnetic field stops changing and treat it as an endstop.

you can have perfect layer and squish.

glass bed doesn't work, too i really like nozzle probing

Then beacon contact it is. Contact doesn't care about different magnetic fields as it looks for a spike or bump in the measurement. So also glass beds until a certain thickness even work if you got some metal beneath it. Currently beacon has invalidated each and every probe on the market, not factoring in price point. Claimed accuracy is extremely good, auto z offset or nozzle probing without the need for tap, piezo or force sensors, so no downsides of those. Tap reduces the structural integrity of the toolhead amd messes up pei sticker build plates, piezo and strain gauge levelling is slow, like 2 or 3mm/s z movement speed, strain gauges also require custom software if you want a actual force readout instead of a simple 0/1 signal

@@kilianlindlbauer8277 pretty much this ☝🏻

beacon has contact mode for nozzle probing that works on magnet inlay bed, glass etc. it can probe on an uncooked egg. it is currently the most accurate, lowest force contact probe. with magnet inlay bed you cant use scanning mode but the new nozzle probe contact mode does work and is still mega accurate, more accurate than anything else on the market.

How so? It’s focused on Eddy because I’ve already made a dedicated video about Beacon. Eddy is cheaper and smaller, which makes it the preferred option in my opinion.

How so?
