should be possible with adding another placeholder , same principle as i did with the work coords.
will take a look at that and make a suggestion , may take a few days so i´m busy on other things.
to show spindle speed we would have to implement pwm for cnc , so as mostly all VFC´s are different
we need to set the rpm to pwm range in config.
simple solution is just showing mode or spindle active respectively laser active.
1st. possibility , no placeholder, just show "Laser" or "CNC"
2nd possibility, using M3 / M5 command to show " Laser ON" or "Spindle ON"
3rd possibility, placeholder calculate rpm on PWM setting and show spindle rpm or Laser %
what do you think?
