M80 - Power On

control Turn on the power supply PSU_CONTROL

Turn on the high-voltage power supply. Requires a board that’s powered from USB or another 5V source.

A PS_ON_PIN is also required. Check your board’s pins file for the default.

For Marlin 1.1.9 and earlier this feature is enabled by POWER_SUPPLY.

Some octoprint plugins filter out M80/M81. If M80 does not work, use a plain serial terminal first prior reporting a bug.
