@madeinta1wan Can you figure out what files are taking up the most space? If you have an old DuetPi version installed, make sure rsyslog isn't installed (sudo apt purge rsyslog), because that used to log a lot of stuff without ever purging the log files, which gradually filled up the SD card.

@kiendeleo BTW the reason we suggest a resistor instead of a direct connection is so that in the event of a short between the hot end metalwork and the hot end heater wires, you won't get a large fault current fed into the ground pin, which would likely damage the tool board.

@phaedrux I didn't find that forum post when I searched for this error, weird. Thank you for your help.

This was the fix:
@chrishamm said in MotionWebcamServer plugin - Missing library:

@adammhaile @luckyflyer Very odd, it looks like something changed because this definitely worked for me before on another image. The problem is indeed that motion cannot open /opt/vc/lib/libvchiq_arm.so. To fix this, you can edit /etc/apparmor.d/dsf.MotionWebcamServer and insert a new line below /usr/local/lib...:

/opt/vc/lib/** rm,

Then reboot the Pi or run sudo apparmor_parser -r /etc/apparmor.d/dsf.MotionWebcamServer and you should be able to start the plugin from DWC.

It looks like there is also an issue with Motion's custom log file location for permission:

motion[1762]: [0:motion] [EMG] [ALL] motion_startup: Exit motion, cannot create log file /var/log/motion/motion.log: Permission denied

This is an optional configuration item though so the short-term fix is to just disable the feature.

It looks like the issue was a reversed power and ground wire on my magnetic filament monitor. 🤦

By way of wrapping up this thread, the solution I found that works well is as follows:

Power Supply 24v to the board, a 5v Converter, and a USBC Converter. The 5v converter is wired to the 5v external power header on the board with the jumper selected to the External 5v. The 5v converter is also wired directly to the Neopixels that I am running to ensure that they get sufficient power in case there is a limit through the board ( I am using 60 Neopixels for this printer) only ground and signal are hooked to the LED header on the board. I am powering the Pi4 off of the 24v to USBC converter.

@chanabra I know it's been a long time but we are working on it!
