Its been a long time coming but we are finally starting to see USB toolhead boards releasing. This is awesome for anyone doing custom printer builds or looking to upgrade their printer. In this video, we look at Nitehawk SB, a 2 piece toolhead board from LDO designed specifically for the Stealthburner toolhead. We go over its specs, what included, how to install it, and I share my thoughts along the way.

You don't have to keep doing the thumbs up swoosh if you don't want to.

I'll still like your videos if you don't 👍

Last week, my coworker recommended that I check out your channel. It turns out we both knew about your channel 👍

I'm not super surprised that the rpi 3 is getting overloaded with a 4k camera plus a usb toolhead.

[ocieward]

OMG, you really did get right into it without further ado! Bravo!

[circuitguy]

This is amazing and well-timed. I broke a wire in my Voron cable chain and have been putting off the 'fix' and upgrade to a CAN toolhead.

[TheDarkRumor]

actually you can also use the bigtreetech EBB36 (probably also the EBB42) over usb, you just need to flash klipper and of course add a 24v power cable

[rafaelguida]

This board is EXACTLY what I needed, thanks a lot for bringing this to our attention Modbot! As someone who's left a hypercube on standby for a year for the shear laziness and lack of time to do the toolhead wiring, this is just what I was looking for! Coming pre-flashed is such a nice touch! I wonder if it'll work with my manta and CB1

[heyitstor]

I installed this on my trident and its an amazing upgrade!

1:09 Nice Omnifixo Cameo! Such amazing tools.

I've had so much trouble with the dwc USB stack on the pi3 and older. Even without any high speed devices, the driver tends to lock up the hardware when handling a large number of transactions concurrently.
In many cases, it took a hw power cycle to clear

[matteoparenti]

Troubleshooting CAN bus is easier than troubleshooting USB. The HAL and packing both on the SBC and MCU side is really sturdy, so you won't need to dive into the packet dumps to search for a missing one. The protocol includes error checking, so you don't really need to worry about retransmission either. The only thing you need to consider are the service on the SBC (not an issue, single config file to edit) and the hardware (which boils down to terminations and good contact). If things go wrong with USB on an SBC, it could be the drivers, the platform-specific microcode, the USB controller, bandwidth issues with a shared port, and so on. Without even talking about the lack of error checking, the much more fragile signal integrity and transmission lenght requirements, etc. It's not really an upgrade in terms of reliability, for sure.

This is a great video on Nitehawk... really well done ! I'm really happy how well Nitehawk is working out, Nitehawk36 is going to be awesome when it's available

[UloPe]

I also don’t get the “finally”.

The EBB36 has a usb-c port and has been available for quite a while now.

[ppak]

I got the same communication error while homing for a Canbus setup (BTT EBB36) and for me it stemmed from a bad cable connection to the board.

I mostly noticed it when the Canbus cable started to bend during the homing sequence and I fixed it by re-crimping the cable connection and keeping that Canbus cable extending from the toolhead fixed upright (preventing any bending around the cables around the molex connector).

I'm using a Raspberry Pi 5 along with an Octopus Pro controller board.

[crossbonefpv]

Great video, to the point and clear. Sadly my Nitehawk36 was a dud, could not be detected as an usb device. Had to take the soft recal from LDO, in about 2 month I'll get a new one. Meanwhile I'm going for the EBB36.

[edwardboston]

Any information on how you de-pinned the connector?

[orthotron]

The CAN toolhead boards you showed (EBB36 and EBB42) already support USB

[GreenPlasticWaterCan]

USB toolhead boards existed for years. The EBB36 and EBB42 could be run over USB.

[jimsoar]

For anyone struggling to find the device in the USB list try changing the USB port the (in my case the octopus board) uses to another port for some reason once I moved that the toolhead showed up

[Thomas]

I dont get it, USB toolhead where around for years, they could just do CANBUS, too
