I'm printing on my Prusa using Repetier-Server on a raspberry pi 2 for a while now. I'm quite sattisfied how it worked till now.
Last week updated my Repetier-Server software to the latest 0.70.1 version, uploaded the printer settings and the printer was up and running again.
Now I also tried to configure an old USB webcam within Repetier-Server to be able monitoring the prints. I've used the instructions to install a USB webcam on my Raspberry from here:
I've managed to get the webcam working and recieve some images in Repetier-Server. But when I've tried to move the printhead and the bed, it doesn't react annymore.
When I power off the Raspberry, remove the USB cam and power up the PI again, then everything works again when I give some movement orders in Repetier. And it stops reacting when I'm plugging in the webcam again.
Maybe someone is familiar with this issue?
Thanks in advance!
Thanks for your response!
Maybe my interpretation of your question is wrong.
But I'm believing I'm using port 8080 for the webcam, since I've also selected this port in the webadresses in Repetier settings. When I start up the Raspberry and Repetier Server (automatically start MJPG-streamer) then I got to see actual images of the webcam in Repetier Server. But I'm not able to activate anny stepper motors (I can still activate and adjust the heaters from this point).
When I'm stopping the MJPG-streamer with the following command "sudo /etc/init.d/mjpgstreamer stop", The webcam imgage in Repetier get's blanc, and I'm recieving no more images. But the stepper motors still won't react on anny command from this point.
I have to shut down the Raspberry (and repetier server running on it), unplug the webcam and start everything up again to get repetier Server (and stepper motors) work again.
In short: when the webcam is connected to the Pi, only the heaters will work in Repetier. When I disconnect the cam from the Pi, and reboot the PI and Repetier, everything works again.
The webcam that I use is a brandless chinese one I believe. And I'm configured it at a resolution of 320x240. The Pi and the printer are on seperated power outlets. And the Pi and webcam are not mounted on anny moving parts.
