Improved cooldown timer

[frankvdh]

Currently, the cooldown timing is simple clock time from the start of the work, not taking into account the time that the laser is actually on or off. So for example, I have had the machine stop when it was just moving the axes with the laser off.

I propose that the cooldown timing be along the lines of...
Every second:
If the laser is on,
Add 1 to the timer
If the timer exceeds the maxtime
Turn the laser off
If speed of either stepper is above max jerk speed
// Need to decelerate the steppers if speed is above max jerk
Record X, Y position
Decelerate to max jerk
Stop movement
Position at below max jerk speed to the recorded X,Y
endif
Stop motors
Pause for the offtime
Resume motion with laser on // Accelerating to specified speed, so also ramp up laser power
endif
else
Subtract offtime/maxtime from the timer // So time spent with the laser off during positioning counts towards cooldown
endif

cooldown it is not something achievable in these terms
