I'm glad Beacon offers touch now. There wasn't an alternative to the scanning z probe from duet until mellow fly came up with their fly sht v4. I put one in a box with the two duet 3 6hc boards. The ebb 36 ad an issue early on with the band width. Since version 3 it is 1 million.

It has been a long and winding road.

Big Tree Tech and Carto are made in China.

Raspberry pi and Duet is made on Great Brittan.

VORON is designed in the East and parts are mostly sorced from China.

You have a few different options depending on if you use USB or CAN.

USB:

• Plug into a Nitehawk (or similar)'s tiny USB port
• Wire straight to your Pi. The included cable is NOT rated for cable chains, so you'll have to use an umbilical. I installed this on a Stealthchanger, so I just installed an umbilical from the shuttle.

CAN (from what I understand, but I've never used CAN before):

• Wire inline with your toolhead CAN

This is good to know!

So with a NiteHawk-36 I need only one USB cable!

But this is not a two piece Toolhead-board, so removing the SB-Front is more difficult, not only plug in. Or is there a NiteHawk-USB with two piece toolhead-board too?
The two piece CAN-Board has only a GPIO-Probe input.

Remains the solution with a second USB cable to the Pi (I think this is what you mean with "Wire inline").

The sensor is not the reason why I will refurbish my old Voron, but I think the refurshing is a good time to look for alternatives. 

Yup, I've rebuilt my Voron 3 times now. This last time I replaced all of the gantry joints and belt tensioners with CNC parts. I redesigned the rear filter to use off the shelf hepa filters and a ton of other stuff, I  design for a living so my natural instinct is to discard some already working thing and redesign it thinking I somehow know better. As for this thread... I became a fan of the Beacon probe when I built a VzBoT and now every printer I have has one. Everything else pales in comparison, IMO.

[PFarm]

I second the Beacon probe, well worth the extra $$, great support, and it just works!

[polyneutron]

Nighthawk installation is: connect an included intermediate board usb c to the usb of the pi or cm4. It also has wires for  24VDC. From there, an umbilical cord goes from one end of the intermediate to the tool board. This cable fits 500mm tall with room to spare. Then a shielded wire goes from the usb pass through to the eddy current probe (Beacon or Carto). My intermediate board is mounted to a din rail with a clip near the manta. On the ender 5 plus i mounted it with a stand off and screw ito the side mounting for the psu.

[polyneutron]

Everything you need to install the night hawk is included with the purchase of the tool board. It also came with a jabberwocky kit and/or a complete assembly. It is similar to the deut can system which is daisy chain. Going from klipper to gecode and back to klipper is a pita. It is now one or the other, not both.

[polyneutron]

Nighthawk nakes one for square motors too.

This is my plan too, as I have broken xy-joints and belt tensioners. I already ordered a chaoticlabs cnc kit for that.

I see! This is an advantage. Is it in the download section?

Myself, I´m not P----- O--, This sentence has a kernel of truth, but take two things in account:
1. For chinese people it is a compliment for the inventor if his invention is copied. He does not see the problem as we do.

2. If "western" managers optimize their profit by manufacturing their goods in Far East, teach the people there, how to produce these goods,  you can not expect, that intelligent, inquisitive and ambitious people will not exploit this and want to take part on that profit. Chinese can not be blamed for this.

Sharing knowledge, doubles the knowledge, unfortuneatly not the profit 

Agree, it is a much more complex dynamic than my very simplistic assertion. Irrespective of the rhetoric, I'm also not angry nor am I pointing a finger to blame, rather I'm just stating what is, to the best of my ability. We all have to deal with our own unique situation. As a designer of medical devices, we rely heavily on the craftsmanship of the eastern countries. In the end, we're all exploiters of whatever resources we have available to us. It's human nature to exploit, that's how we got here. 

[Repman]

@Penatr8tor Agree! If we stay fair, everyone has his benefits all over the world, even in Greenland (You know the big island that belongs to Denmark .-)

[Penatr8tor]

@Repman I have a build diary and all of the mods I created are embedded in that thread.

Here's the page where the filter is. I don't think I have a link to any of the files. Take a look and if you're interested... I'll post the STLs and STEP files for you. There's also some good stuff in there you might also like and a couple CAD tutorials of how I designed some of the mods.

Thank you very much, I will get back to you on that.

Thingivers has a real hepa filter that really does work. I would use a carbon filter for VOC's and distributing warm air into the enclosure. The hepa filter hags off the back at the top.

Here is the picture of the Voron and Hepa Filter. I found the hepa filter on thingiverse as a real hepa filter. It and the nevermore V6 have worked very well to maintain temperatures and get rid of any and all oders.

[Repman]

@polyneutron Yeah that is german technology from Björn Sanders. I wil tryout this one! The Miele Hepa filters are easy to source here.

At the moment I am using the V2.4 Aire on each bed side (https://github.com/VoronManiac/V2.4-Aire/blob/main/README.md) and my exhaust blows out of the window via an extraction hose (originally for woodworking machines: https://www.holz-metall.info/Absaugschlauch-60-mm-Spiralschlauch-fuer-Absauganlagen-Standard/MHM21310

the other end is normally connected to the standard exhaust of the voron (with some black filter grid). The smell in my workplace is moderate even if I print standard ABS. The disadvantage is that the window has to stay open, which is problematic if it is windy and cold. In the moment it works without a hepa filter (apart from the filters in the Aire). 

 

[polyneutron]

Sounds like a step in the right direction. But I plan to hold steady until the need arises.

I think it also depends on what kind of material you print. Some days ago I printed seven years old ABS. The smell was horrible and I asked myself, how did I manage that in earlier times

[polyneutron]

I print ABS, Nylon an true PC. I also run a IVOTION ozone and uv home system. This is for our health and eliminates smells and oders. The carbon filter helped, but the hepa filter got point it no longer smells. The ivotion has a hepa filter as well. They are all changed every 2-3 months. That a 5015 fan will work with carbon filters. They don't supply the volume of air that hepa needs.

The size of your Wathai-Fan is 120 mm x 32 mm, 24V, right? I found one with GDSTIME, which should fit.

 

[polyneutron]

Yes. It is the volume of air not forced or focused. Uniform. There is an air gap beneath the filters where the air comes in.

[Repman]

OK, alea iacta est:
I will go for the cartographer.
After the input here I was torn between cartographer and beacon.

The reason for my decision: I will go for CAN on the toolhead and the direct connection of the cartographer to that toolhead has a certain charme. I will try that.

Thanks to all again for your Input and opinions in this issue.

[NikosSprocket]

I have a question about Beacon used with “Contact method”. Will this introduce the oozing issue for z-offset?

If there is significant oozing, like TPE 83, which usually does during initial calibration even at lower extruder temperatures, will it still “sense” the metal bead and stop when there is a non-metallic substance at the end of the nozzle, and it will be the same problem with other “Contact” z-offset methods?

Finally, it will be great if they had a CAN version, so another USB cable get eliminated and use existing CAN network on the toolhead! The whole point of using CAN network is to eliminate as many single circuits as possible!

I fully agree that inductive probing is superfast compared to mechanical probing like TAP which has the following limitations:

• Extruder cannot be more than 150 deg. Celsius during TAPing to protect various bed plates.
• Slow as every Z movement during calibration has to be performed in slow speeds.
• Oozing on the nozzles gives inaccurate Z-offsets and mesh.
• Extra weight due to the extra small linear rail etc.

On the other hand:

• Very simple operation using a mechanical or optical switch.
• Can easily be integrated to any toolhead board as an "endstop switch”.
• As long as it is configured and wired properly it will stop the head from crashing on the bed in case of some other system malfunction.
• Not requiring another USB cable to be wired all the way to the Pi!

By the way, this is only an academic discussion and NOT an inductive probe ...
