Checked. It was about relays and laser, nothing about rotation of the motor with preset speed, like M3 S1000.

Try
M3 $1 S1000
Since LinuxCNC 2.8 (i think) there is built in support for multiple spindles, the $n should be the G-code controlling the spindle number where n is the spindle number starting from 0 (zero), so $0 is the default first spindle, then $1 is the second spindle, etc.
