Once again, Creality like to break stuff. IIRC that's Marlin 2, but to Creality its 0.0.6...
I am confused. Are you saying I have the latest version of Marlin?
Not quite, since Creality fork the firmware, develop their own bugs and then ship it with their printers, they decide to mess with the version numbers too. It is at least from the last year, not 10 years ago that official 0.x versions would have been released. I would still recommend updating.

Thanks. I ordered the BTT SKR Mini E3 V2.0 w/ touch screen. Should be here by the weekend and I'll have my next project. Compiling marlin seems to involve many steps I'll have to review the above video carefully. My programming skills are very rusty and the languages they have these days are pretty foreign to me. I do recall you can write a program 99.9% perfectly but that .1% error will keep if from working 100%.
I installed the BTT SKR Mini E3 V2.0 w/ TFT35 E3 several weeks ago and Put the Marlin 2.0 bug fix on it. Things seemingly went well til yesterday. After mounting the Pi cam atop the top cross member of my E3 Pro looking downward onto the building platform I decided the view would be better mounted on the right side of the x axis. I printed the new bracket and case and transferred the camera. I lost the image. Thinking maybe I had damaged the ribbon I changed it out but that did no good. I have rebooted my PC as well as my RPi and printer but that doesn't help. I get a 503 error code on my octopod app and Octoprint says web stream not loaded. When I test the connection in settings I get " If you see your webcam stream below, the entered stream URL is ok. But I don't see any stream. I am wondering if I should go back and try the 32 bit version of OctoPi like you suggested previously. I am pretty sure I'm running the 64 bit version of .18 if I am getting my versions correctly. I recall the .17 download I initially tried didn't work at all. My RPI is the 8 gig 4B.
As an aside I also noticed the Arc Welder plugin doesn't give a version number in the software updater and gives an error message when it tried to update. It refers me to an error log which I do not know how to find. I did comment the arc support line in the marlin firmware when I loaded it onto the BTT SKR Mini E3. Are there other lines I needed to comment perhaps? Do you think my two problems could be related?plugin_arc_welder (1).log (861 Bytes)
I just found a log for arc welder that may or may not help with the plugin problem.
I'm trying to find the Pi cam log but to do that I need to log directly into the Pi via SSH. I use Putty and it asks for a username and password which I forgot. I assume the solution is to reburn the image file to the SD card for the RPi and start over and write the username and password down this time. I will report back with the log for the Pi Cam and can start a new thread about arc welder if preferred. For arc welder it seems to work so i'm guessing there may be a bug.

Well, I got around the SSH login by creating a text file with the password on it. Thanks to the person on another thread who suggested that.
Now that I can log in to my RPi via SSH from my desktop I can’t find the cameras files listed in Gina’s awesome post on getting the PiCam to work. Putty is a very basic terminal and I figured out how to get a list of files but none seem to match the ones she mentions. The user interface is not very user friendly and I feel like I am missing a crucial piece of information needed to pull those files.
Check the connector of the camera module itself on the camera board. Maybe it has loosened
If that doesn't help upload the webcamd.log
Yeah you need the 0.18.0 image for that pi

Thank you. I have checked and rechecked both the direction and seating of the ribbon both on the board and on the camera multiple times. It isn't a deficit of knowledge or skill in this regard. No overt damage to the board or camera are noted. the cable was a little deformed by the enclosure but I tried a brand new cable and at this point everything is out of the enclosure and nothing is kinked or deformed. I imaged a new copy of .18 64bit Octopi on a new card and set it up but the camera still isn't running. I ordered a new camera to see if that is the issue. It should be here tomorrow. Also considering trying the 32 bit version of Octopi. The only last thing is the webcam server logs on the Pi. I know how to log on vis SSH but i am not facile enough with raspbian to know how to access those files. I tried attaching a .txt file of the SSH screen from yesterday but format isnt recognized by this editor.
im using the 64bit version. do you think that may be the problem? The camera ran well for a couple weeks on the 64 bit version until I moved it from one printed case to another. I didn't shut down the Raspberry but I didn't disconnect the cable either-just moved it from one printed box to another.
/var/webcamd.log is the webcam log, might help. Every time you do something like disconnect & reconnect, run sudo service webcamd restart and that will make it look for the camera & start up the streamer - if it gets disconnected, the stream stops (for obvious reasons...) so it needs to be restarted, if you haven't been already.
Upload files using drag-and-drop, or the button with an up-arrow: 
I see. Is that a snap fit connection or a soldered one? I will take a closer look but was afraid to mess with it for fear of damaging it. I'll try and get a picture of what I have but like I said there is no overt sign of damage. The lens isn't hanging off the board and the board isn't cracked, scraped or burned.
Here are some pics of my cam-
I ran sudo service webcam restart last night and got back multiple lines of text which might have indicated the problem. i didn't know how to get what is was seeing on the terminal to the discussion board here so I copied it to a pasteboard than created a .txt file using notepad++. Unfortunately this discussion board wont allow me to upload .txt extensions using drag and drop or the up arrow symbol.
this is the message I got when I ran sudo service webcam restart

It's snap fit
you could loosen it with you finger nail and just press it on again afterwards
The output of journalctl -u webcamd is cut off in the middle. Maybe you could try to copy it from a fullscreen putty window
Well, I got a new camera today and put it on but my video still doesn't work. I'll try the restart command from the SSH terminal when I am between prints. If that doesn't work I'll see what the webcam log reads. I was getting some weird messages when trying to update arc welder-like it couldn't find the update even though it was working. I uninstalled then reinstalled the plug in but the error message persisted. That cleared up when I imaged a new copy of OctoPi .18 64 bit, reconfigured the firmware and reinstalled the plugin but then I had a bit of trouble getting the Octopod app to recognize my printer. I manually entered the IP address and now it intermittently works. The Pi cam still doesn't work. I have to think either I'm not configured properly somewhere or there are bugs. Perhaps I should try the 32 bit OctoPi?
Before you try that post me the full line of the V4L2 device from sudo journalctl -u webcamd
I just want to know if the right device was selcted.
This is how it should look like

still cut off in the middle of the line 
Did you try it in fullscreen?
Was in the process of editing when you caught my error. It is corrected. What is the notation about starting a usb webcam? is that because im set to auto? could that be the issue?
I see it still cuts off. How are you posting your expanded version? Straight from SSH? I'm copying the SSH screen to clipboard then opening it on notepad. Maybe I should use notepad ++
now it works - the end is just in the other line
You can use the </> button to put a marked text in this box.
That souldn't be the issue but let's check if the cam is recognized by v4l2 at all
try v4l2-ctl --list-devices and post the output
