M999 - STOP Restart

control Return the machine to Running state

If a STOP occurs you can use M999 to restart the “stopped” machine after resolving the issue.

Marlin will call STOP if any error occurs that would make continuing the current process problematic. For example, if the probe fails to deploy, it will abort probing and STOP. Note that this disables all heaters.


M999 S<bool>

Argument Description

Resume without flushing the command buffer. The default behaviour is to flush the serial buffer and request a resend to the host starting on the last N line received.
