Assembly:
Base:
- Place the M3 inserts for mounting the sides
- Place the M2.5 inserts for mounting the RPI and the LED mount
- Mount LED strip to LED mount
- Use 2x 2.5mm screws to mount LEDs
- Use 3x 2.5mm screws to mount RPI
- Connect LEDs
- Mount sides using 8x 3mm screws (The logo side includes the difuser and difuser shield)
- Optional the support material in the base can be removed to route the cables
- Add the rubber pads
Roll:
- Use the M4 screws to mount the lock to the roll (Optional a ball bearing can be used) When using a ball bearing the roll may unwind itself. If this happens you can tighten the M4 screw or remove the ball bearing.
Cooling:
Tested with the Raspberry PI 3 B+ without problems. But the board gets pretty hot with the upside mounting position and no airflow. For the model RPi 4 forced cooling probably will be necessary.
OctoPrint plugin:
Use the excellent “WS281x LED Status” plugin to control the led strip.
Tested with the SK6812W leds. Reduce the brightness to reduce power and extend lifetime LEDs
