Plugged into monitor and keyboard for setup.
Interesting - just tried loading the image fresh a couple times and sometimes SSH works and others it does not. sshd fails to load saying āCould not load host keyā
Wonder if something with the way Iām building that image is corrupting those host keysā¦ Iām going to give a shot flashing the non-shrunk image (I use pishrink to decrease the size of the image we provide) and see if that works reliably.
@tonyn79 What model Pi are you using?
Yep - that seems to be it. pishrink is somehow mucking with the ssh keys. Will get that fixed.
Mine is too but it only shows the status page on the monitor.
Mine is a 3B
Strange, only thing I did from a fresh load was adding the ssh file. Mine booted to terminal.
RC2 booted to terminal. RC3 boots to a ādashboardā.
@BlomsD - just Ctrl+C at that dashboard and itāll go away, bringing you back to the console.
Thanks. I will try that very soon.
EDIT: CTRL-C worked great. Got to the terminal and then ran:
$ sudo rm -r /etc/ssh/ssh*key
$ sudo dpkg-reconfigure openssh-server
now I have SSH access. Now I can begin messing with the camera until your real solution comes around.
Wow, thatās a serious bonus - I hope it all goes well!! I use multiple Rasberry PIās to interface with my printers over WiFi and they are indespensible. To have this connection to the camera and laser would be very awesome! Right now I had to move and dedicate a laptop to my laser cutter so I could use my lightburn camera (which is a HUGE game changer by the way).
Is there somewhere we could sign up for alerts on the progress of the camera over Rasberry PI?
Thanks,
Mike
EDIT: On second thought, this does not work yet. I can run VirtualHere on the bridge but when I send commands via the bridge it drops VirtualHere. It can come back but it alternates back and forth which part is working.
This is definitely not as smooth as the integration that you all are coming up with but this is still pretty cool. I was able to get my Lightburn Camera to come across the network from the pi. I tried to use usbip as built in to linux but couldnāt get the windows client to work (youtube video above). So I switched to VirtualHere. You can use one device for free. Here is the tutorial I generally followed but my version is below. How To Share USB Devices Over Network with VirtualHERE on Raspberry Pi - YouTube
Here is how I set it up.
- Remote in to the raspberry pi (or run the commands from the pi itself)
- If the dashboard is displayed press CTRL-C to break out of it to get to the command prompt.
- Download virtual here for the Raspberry Pi
wget https://www.virtualhere.com/sites/default/files/usbserver/vhusbdarm - Set it to be executable:
chmod +x vhusbdarm - To get it to auto-run edit:
sudo nano /etc/rc.local - dd a line after fi and before exit which has the local of your file and with a -b for silent running. Mine was:
/home/pi/vhusbdarm -b - Write the file (CTRL O) then exit CTRL X
- Reboot the pi with:
sudo reboot
Now on your windows or mac machine download and install the client: VirtualHere USB Client | VirtualHere
Run the client and it should see your VirtualHere client. Right click on the device and click Use This Device (or if this will always be the device then click Auto-Use Device). If you havenāt installed the camera on the computer it will install the drivers.
The camera should now be visible in Lightburn. Iāve noticed a little lag in the process but to get the trace and do alignment it seems to work okay.
@BlomsD @tonyn79 fixed out the ssh thing. PiShrink was screwing up the host keys. Next RC image will be fixed.
Nice, I will be sure to get the next update. A little off topic, any word on head mounted camera options?
Itās partially done, but Iāve been putting out non-stop fires since the Mac communication issues started (among other things) and havenāt had a chance to get back to it. Itās āfunctionalā but needs a bunch of UI cleanup and tweaking.
Iām eagerly following this thread as being able to stream the webcam over the Lightburn Bridge pi would be amazing! It will make it easier to position the laser and means it can become completely untethered from the computer. Iām happy to test any dev builds with my Logitech webcam if thatās helpful.
btw, is light burn bridge open source, or even āsource availableā? I could only find a download link for the image which is fine, but it would be nice to see how it works if itās available.
Iām not planning on making the source code available, as itās quite tightly coupled with how LightBurn communicates with the device itself, and thatās encroaching on our āSecret Sauceā. We also donāt want people modding it, because inevitably someone would ask why itās not working, and Iād end up debugging their code. Debugging my own is bad enough ā¦
No problem, totally understand! I donāt want to seem like a pain, but do you have an updated ETA for when the camera streaming might be included out of the box in the LightBurn raspberry pi image? Cheers!
We do not provide release dates as this is software and things come up. We have a bunch of this work completed, but need to hook up all the UI and LightBurn side of things so, soon-ish.
This last couple weeks has been a fire hose for me - one of our main support folks is out sick, so Iām picking up the slack there, weāre training up a new shipping person and teaching him to use the lasers so he can start doing general support as well, and Iām still the lead developer. This is why we donāt give hard release dates.
That said, itās on the list for ānear termā - I want to get back onto this soon, but Iām trying to sort out some bugs and communication issues on Mac first.
Totally understand, thanks team! Iāll be sure to keep an eye out.
I just want people to know we arenāt stalling intentionally or anything
We try really hard to prioritize existing customer support and bug fixing over new features, so things take longer than I wish they would, but when itās your bug, youāll be happy we do it this way.
