Host Command Reference
SM - Stop Move
Compatibility: Q drives only
See also:
AM, DE, JL, SK, ST, QK commands
Stops any type of move in progress* such as FL or CJ. This command acts like the ST (Stop) command except it
will not stop a wait operation (like WD, WI, WP, or WT) and it can be part of a stored Q program. The contents of
the queue are not affected by the SM command
* = Exception: SH
NOTE: Requires Multi-Tasking to be enabled (MT1). By default Motion-Tasking is disabled, which means the
current move must complete before any subsequent buffered command (such as SM) can execute. With Multi-
Tasking enabled, subsequent commands may be processed while a move is in progress and the SM command
will execute properly.
