Pause job immediately when lid opened

[paulg4h]

@o_lampe RRF knows the start and target point with the path and speed it moves so it should not be rocket science to calculate the position where it is at any time.

@paulg4h said in Pause job immediately when lid opened:

M120 and M121 to restore the Laser power, but when I move the head away on pause and return it on resume the laser switches on before the head reaches the last position.

You can avoid the laser turning on if you use G0 moves in pause.g and resume.g, not G1 moves.

You can get a faster response to the pause by using firmware 3.3 and enabling segmentation. See the S and T parameters of the M669 command.

@dc42 many thank's!

I add this line in my config.g

; Set Cartesian type and segment interval one second and length 3mm
M669 K0 S1 T3

In the middle of a 200mm straight cut the pause will be done within the second and move set with M669

So this works and I will add this line to my CNC too, btw. I do not see any slowness in normal cut and engrave jobs too.
