EBB36 - CAN Toolhead board

[Dirk]

Yesterday AliExpress forced a promotion from BTT in my face when I was checking on my orders.

I have now fried a Fysetc Spider 3.0 MCU and my SB2209 when I misaligned the pins of the HartK designed front piece a while back. Since I have bought another SB2209 and a mellow one and am using it, every time I am coupling the SB front on the toolhead, I check 10 times before doing so. 

I have also seen many people that have done the same as I did, which made me wonder why BTT does not make a simple solution for it, like making it so, that it is dummy proof. I even wrote to them and they replied to me with the standard useless: " we will present it to our development team".
Meanwhile I know it means there is no development or technical team, that is innovative. BTT just seems to copy stuff that is already out there and sells it thanks to their massive marketing machine. 

I have been considering the XOL toolhead, and found it actually refreshing that it does not have this awful 2 part. It will also give me the chance to finally use the (meanwhile outdated) Orbiter 2.0 which I could not use because of the incompatibility with the HartK 2 part toolhead design.

The toolhead works with an EBB36. A quite popular CAN toolhead board. Not only for the Voron printers, but for many others that want to make the switch to CAN (vzbot / Enders and so forth). So I was quite happily surprised that I could get it for a ridiculously low price. So I got myself 2 pieces for 24 euros.

After I did that, I wondered why BTT was trying to get rid of their EBB36s... So I looked around and found out about the newly demonstrated Nighthawk36 by LDO. So I am guessing that they might be updating their ebb36 to a can/usb combined version. To be flashed to whichever mode you wish. Similar to the Cartographer probe. And the Fysetc toolhead in development I wrote about a while back.

Which gives more options for everyone

I used this on both of my printers SB2209. SB2209 Alingment Pins STL

so did I

they fall out. and I tried misaligning it with it in place, you can do it.

A simpler solution would be, to make a pin that can plug into another one in only one way. there are many ways to do it safely. But BTT is too ignorant / lacks technical people to do that. They just copy and reproduce. 

And do not listen to their customers.

That is what I was trying to say

There should now also be a orbiter 2 specific can board from Fabreeko, might want to check it out.

orbiter 2 specific

The only extra it has, is for an orbiter specific sensor. Not in the orbiter git, this specific sensor.

All the features are also on the ebb36. Except the usb, which I have no need /use for. 

For the price of 50€.

No thank you. But thanks for the info

I modified my Stealthburner to fit the Orbiter 2 with the SB000000 and the SB2209. I went this route because I thought in the end it was the better choice with more options, including a nice umbilical cord which would prevent the dreaded wrong connection.

Boy was I ignorant! I ended up having to remove the female connector on the SB00000 board and wire the connector to the board so I could plug it into the SB2209; the Orbiter blocked the connector.  After designing and printing new parts and supports I finally got it assembled and working, but would have been much easier and safer going with the EBB36.  Next time I'll ask around before buying

Price is definitely tough to swallow 

However I have found the sht36v2 and now the v3 as well to be more useful than the ebb36. Precrimped can cables, fan voltage selection, and lis2dw are small but decent improvements.

fan voltage selection

I think every improvement is good. 

I recall one of the reasons I installed SB2209 first on my system, was because I only had 24v fans for the SB. And EBB36 did not support it. Meanwhile, my collection of fans has grown, and a 5v fan is also is common in my drawer. I also bought the Mellow SHT36v2 which came with a can cable. I like the one from BTT that came with the SB2209 better. and if I have need for one, will purchase from them (5 euros). Maybe not a bad idea anyway, for the drawer 

The EBB36 also has an ADXL345 on board. And if you wish the max chip.

What I have found to be very important in DIY 3d printing world, is that support from the community. Almost every toolhead board has a mount / mod for the EBB36. The EBB36 only has two ports for a 5v fan, and a very popular toolhead, the XoL needs three! There you go! 

I hope galileo and all the accesoires will get as much support

Mellow do pack a better cable nowadays with the v3 so that’s nice.

My understanding is the EBB36 fan voltages are whatever you are supplying to the board. I was concerned I bought the wrong fans, but I measured the voltages of the fan ports and they were 24v, which matches the voltage I am supplying to it. I do wish it had 3 fan ports as I am using it with DragonBurner.

[Dirk]

Oh, interesting. I have never tried doing that. Although... The documentation says the input can be 12-24v, logic voltage 3.3, the DC-DC voltage 5v, 1A. 

I am supposing with CAN the voltage is always 24v. Well.. Means I will have to check the output voltages of the fans out as soon as I get the thing

If you want 3 ports, use the jst mod from Esoterical I posted above

it was the better choice with more options

The 2 part pcb was initially designed by Hartk for the non can versions of stealthburner. The sb pcb was meant to easily plug in your two fans and the sb leds. Not to connect a can or whatever connection.

Btt and others blindly copied it without seeing or realizing the consequences.

Not a bad idea, but they could have upgraded when they saw problems. They didn't.

And the orbiter has been promoted like crazy in the community and has been popular but nobody took the effort to develop a good solution like you had to make for yourself.

Now the Galileo is released, it is suddenly all possible, because the community developed it and the kits are being sold for about 4 times the price of a cw-2. 

I checked out the Galileo cad and compared it to my orbiter 2 and 1.5 to see if I could use it after disassembling it into parts. But unfortunately conveniently two of the most essential parts have been slightly modified so it is impossible to do just that.

Not going to buy a Galileo for 80€. Instead I am about to upgrade to an XoL. Which has all the options/mods SB has and more. Even a XoL-metrix mod is available

I will make a post when I have done the switch.

Looking forward to seeing your results.

Everything I have has a version of the EBB36 on it. I have a couple of the EBB42s that will end up in use on my Tool-Changer build, but that is only because I am really really trying not to buy more stuff. I am halfway done with the Tool Changer build and still have enough extrusions and 300/350mm linear rails and stepper motors that I could probably put this SKR back into use and build a 4th printer. But, I might need to buy an EBB for that .... HAHAHAHA!
