 +* If printing from a Raspberry Pi ( e.g. from OctoPrint / OctoPi ), ensure that the Pi's power supply is capable of supplying the required current at a high enough voltage. The official Raspberry Pi PSU supplies up to 2.5A at 5.1V. Low voltages can cause USB communication issues, as well as SD card corruption and other crashes. With a Pi 3 B or 3 B+ you can monitor under-voltage events by watching for the Pi's red power LED turning off, a "​lightning bolt" icon being displayed over HDMI, or you can run ''​dmesg | grep voltage''​ in a terminal/​over SSH.
