3do-eu / nozzle-camera Goto Github PK

I'm having an issue where when my print head goes through the clean nozzle routine it causes the camera to go offline. If you watch the video you can see it go offline right as the nozzle comes in contact with the brass brush. I'm confident it's not a cabling issue since the camera will stay offline until I remove and reinsert the USB cable at my OrangePi. After I do that the camera works without issues for the duration of the print. I'm suspecting it's a grounding issue so I'm trying a few ideas out but I wanted to see if anyone else has also run into this issue.

Is there any plan on making a mounting solution for the Ender line of printers from Creality?

Also, can the critical dimensions for the camera sensor be made available like the PCB CAD model?

If the flat cable connected to the camera is damaged (too many folds, etc...) is there a way to replace the flat cable? Is the camera just e-waste now and the entire module needs to be replaced?

Hullo,

Is there anything in the works to either enable H.264 encoding on the existing encoder board (unsure if this is possible?) or to put out a board that does support H.264?

MJPG is great if you have a GPU / hardware MJPG encoding available, but 3D printer webcams are predominantly connected to arm(64) SBCs which have hardware H.264 encoding, but dealing with MJPG is painful.

Context: I've bought a 4K webcam, capable of 1080p60, but because of the heft of the MJPG stream, I'm barely able to stream the feed at ~20 fps consistently!

Thanks,

Tom

Am I the only one having a hard time figuring out how to route the FPC within SB main body?

What I want and checked:
I'm using the hartk 2 pieces PCB -> How to mount cam PCB?
Checking this issue which is already closed: #Stealthburner PCB Mount?
On the recommended link there is no mount option. That link does not really a mount. Its just some fancy face for the SB and a bit of cutout for the USB cable. There is no proper mount option for the PCB inside the toolhead like the topic opener asked in issue #17 .
Also none of the STLs provided under Cam_mount_SB mod by Panzarkatten correlates to the shown image.
Once you zoom in, the cam FPC cable is either just disappear somewhere in the body or is just folded back. It clearly just not moving downwards. Furthermore, none of the STL has that wide cutout shown in the image. You cannot see anything where that FPC goes as the picture taken on an angle where nothing can properly seen (marked with orange). Its impossible to track/learn how it supposed to be routed and the picture is... ehmm.. kinda questionable.

On the other hand, in the Voron_Stealtburner folder there is a picture referred as "FPC_DONT_PULL.jpg".
The marked with orange part is definietly much longer for the Magnum_plus_UHF than for the 'normal' cam_mount_SB. There is not enough room here to fold the ribbon cable as shown on that picture for the cam_mount_SB. If I would try to do it, it will definietly break the FPC.

The image shows how to route the FPC within the SB is not clear.
The cable channel goes up from the hotend fan to the top part cooling fan is not deep enough to push the FPC within. How is the cable folded there to avoid blocking the air coming from the part fan? From this angled picture its impossible to see.

In general, some of the pictures not correlates to the provided STLs and some of them are either bad or just not clear.
Without clear documentation and pictures the risk to break that weak FPC is really high.
Please provide more pictures aligned with the uploaded STLs.
Please provide pictures created from diferent angle to be able to track how it is designed, how it is supposed to be.

Or just say its not supported to mount the PCB within the SB toolhead. But in this case, do not put a 25cm FPC on the cam, if we have to mount on the ADXL mount point.

The cam mount file is provided as "3NC_mount_geometry_V2.step" to make it easier so we can make our custom camera mount attachments. Is there basic led mount file that could also be provided? Like maybe a segmented version of the attached image? I can try to trial and error my own led mounting model, but I thought it would be a huge time saver if there was an already made mode I could grab and go with. Thanks!

So my first issues was closed without being addressed. Is there an simple mount stl file that could be provided for the LEDs? There is a simple mount provided for the cam itself (3NC_mount_geometry_V2.step). I was hoping it could save me and many others who need to customize things a lot of time.

I've installed this camera with a Rapido hotend. In general it works, but I'm finding that the bottom of the camera mount is just barely above the height of the nozzle tip. Then end result is that if there are any issues, at all, with the print causing any sort of lift or raised filament at all, that the bottom of the toolhead (at the nozzle mount) can catch on the part.

Any chance of modding one of the front plates to have the nozzle cam mount just a liiiiiitle bit higher up?

Hello,
I'm working on my voron 2.4 with stealthburner toolhead. Unfortunately i only ordered the usb cable in 1 m length, which is way too short for my 350³ build... (needs >= 2.5 m)
I provisionally installed the HD version of the nozzle cam using the original usb cable and was happy that it worked there.
After that i cut the usb cable and inserted 2 m of cable between the original plug and the camera side cable (soldered cables and checked continuity)
Unfortunately now the camera is not working anymore.

The situation is:

• camera shows up on lsusb
• camera does not show up in ls /dev/video*
• camera does not show up in dmesg | grep Webcam

I don't get, where the error might be. Thought this might be a problem others stumble accross so decided to report as an issue.

Thx in advance and BR

Unless you are able to mount this at the EXACT distance away from the nozzle tip, good luck in using it. The lens cannot be adjusted, so don't waste your time, or money, trying.

would be nice to change the Connector on the board with something more reliable like a USB-C connector, i have my many trouble with this little 5 pin connector on the board

Could I persuade you to release an Eva3 duct modeled to utilize beacon and the camera also?

I know there's a ADXL mount but it's kind of a little ugly for my tastes. The back of my stepper also isn't available for the 3do pcb as I have a canbus board. I am wondering if someone more skilled than I could create a mount for the inside of the stealth burner where normally the pcb would be mounted as I won't be using said mount that would be the most ideal enclosed location?

I made a simple 3D model of the IMX258 camera. I also added a focus window, for a resolution of 800x600 and a focus length of 32mm from the back of the camera. I tried to measure it today and the sharpest image comes out at that 32mm.

And I'm starting to work on my version for Hemera XS+ 3D printed Hermit CRAB + CPAP blower

btw, what is the best camera angle?

is it possible to use the nozzlecam board and the sb2240 can board together (is there enough space behind the fan)

I've looked on printables and the other site, no one has made a mount for my printer yet Creality CR-6 MAX. The same design would work for CR-6 MAX or CR-6 SE since they share the same printer head design. The MAX may just need a longer cable but that is not a part of the mount.

Thanks!

Quick question - the supplied USB cable is quite 'chunky', is the expectation for Voron users to route the cable into and through the existing Voron gantry cable chains? If so, due to it's size I cannot help but think this would have detrimental impact on the movement of the chains, which may subsequently impact printing/quality. Can you please confirm if this is the case?

Or, are we meant to remove the a majority of the USB cable's outer sheath exposing the five inner cables and route those through the Voron Gantry cable chain, if so, are the inner wires of the supplied USB cable Heflon/Teflon based so that they can withstand the repeated movements?

Thanks in advance.

The model for the cutout main body to mount the PCB with a 2 piece tool board is still the Stealthburner Beta version. There were some changes made to the locating features in the release version that are not compatible. See images below. Can this part be updated to add the cutout to the relese version please?
CW2_main_body_3do_pcb_cutout.stl

Are these going to be available?

Is there a version for the new revo roto and 3do nozzle cam?

Can I just run four 24awg Linneo 40 stand wires from the camera controller board in the tool head to a solder on USB connector at the PI? Or is a larger wire needed? Possibly 20awg?

Also what is the connector type at the camera board? Looks like a 5 conductor connector of some type.

So... Camera works great... when it works of course!

I have it installed on a Stealthburner Toolhead with an SB2209 board and due to the lack of space or better spot to place the camera board, I placed it next to the umbilical cord and secured it with a couple zip ties.

My problem is... camera's working fine and all of a sudden, at random interval it stops working. I have to go, unplug the cable (literally) from the board and once plugged back in it works fine again but it can fail again (randomly).

I've checked with the lsusb after the failure and I can see the device in the USB list.

I have two other cameras and they don't stop transmitting at any point so I'm a bit lost... what could be the issue here? Where can I start the troubleshooting?

Thanks

The board takes up to much space so trying to figure out how to mount the board on this setup. Ideas?

So I've mounted PCB on the PCB_mount_SB.stl, but when testing that things are working I've found out that one of the screws actually squished one of the resistors, I assume and the camera, obviously, was not able to process images. It was correctly recognized as a "PC Camera", but no image was shown.

I've included the location of the element. Can you please tell me what this was so that I can replace it?
Also please, update the mount, so others will not have the same problem

I hope someone is able to create a mounting for the Bambu Lab X1!

afternoon all, just wondering if there is a StealthBurner front availible that includes the knomi screen and nozzle cam? cam board will be mounted on adlx

thanks :)
Stu

Could someone explain to me how i would need to connect the LEDs to some sort of power what would be the best option?
