M codes for a second spindle?

Hi.
Are them already preset in project or them should be created by myself?

Hello,

there is an example:
forum.linuxcnc.org/38-general-linuxcnc-q...indle-flagging-error
 

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.
linuxcnc.org/docs/html/examples/spindle.html
linuxcnc.org/docs/stable/html/gcode/othe...ec:set-spindle-speed

Sounds good. I will try it. Thank you.

It is working. Thanks to you and @dm17ry -- it runs easyli.
