RaspberryCam crashes after printing start

Camera model
RasperyPi Cam

What is the problem?
Hi, the camera itself works great, but when I start printing, the camera seems to crash.
When I move the Z-Axis, it still works, but as soon as i start moving the X or Y-Axis in the control-tab, the picture freezes and i cannot bring it back to work. Only possibility is to restart the system. It all worked until I updated to 1.4.1 and the day after to 1.4.2.
does anybody have a tipp, what I should look for ?

What did you already try to solve it?
tried to check the logs, but I have no clue what to look for.

edit 15:08 07.08.2020: Looked through other threads: tried with Safemode, same result.
restarting the service worked only once, when x-y-Movement is triggered it crashes again and then the restart of the service does not work.
I checked the configuration via ssh, everything fine.
Accessing the Camera with direct URL, does not work.

Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
the only information I could find in logs is this after moving the x-Axis:

I startet the Webcam daemon manually and startet a new print, and there are some details from syslog, what happened when the X-Y-Movement started:

Hope this helps

Does really nobody have an idea ? I mean it is really strange, that a specific printer-movement in x or y - direction causes the camera to crash. z-Movement does not affect anything. maybe @foosel has an idea how this might hang together ? It is reproduceable.
My last option might be is a complete new install from scratch.

Still hoping vor Ideas.

Best gregards

Try making sure your printer is not being back-powered from the Pi. Way to test: Turn printer power off, but leave Raspberry Pi on - does the LCD screen stay lit, or any lights on the printer motherboard?

I'm thinking maybe the printer sucks some power, which could cause the camera to crash.

There is a solution, and it is to tape over the 5V pin in USB cable. If you confirm the above, I can find the guide

hi @Charlie_Powell: when the Printer is off, the Display stays on.
Would be very kind of you to tell me where to find the guide :wink:

Thank you, I will try this evening and come back then.

Did you sort this out? I'm having the exact same problem. (camera crash when moving X,Y but not Z) . I have no 5v back-powering of the printer, so it should be something else.

9

For people having issues there in this youtube video DRVax shows a usb gadget of few bucks that solves the power issue if you dont want to mess with tape.

I solved my problem!
It had nothing to do with back powering as I already had taken care of that.

The problem was interference introduced to the 1m pi-cam ribbon cable, by running the cable to close to the stepper motors and their cables.
This in turn this caused out of spec signal to the board and crashed the camera. The separation needed to make it work was to far for my use case so I made some shielding kind of like this ( https://www.youtube.com/watch?v=8QgT8eiEgFU ) and it seems to work for now.

For the future I'm considering to use the shorter supplied cable for the cam and figure out a different mounting solution because I think 1m for that type of cable/use seems a bit dodgy.

Still don't know what the original posters problem was but if he still have issues and his config is like mine he might want to give shielding/shorter cable a try.

Hey ! Thanks for sharing this solution with us.
