resume.g and using a laser

jgrouse

Hi,

I'm finding that when I pause and then resume in the middle of a laser cut, the resume turns on the laser at full power as it moves back to the point it left. This is the content of my resume.g file -

M3 S0
G1 R1 X Y Z30 S0 F9000

As you can see I am forcing zero power on both lines. It's like the R1 parameter is ignoring the laser power and just overriding with S255?

Bug or wrong command to go back to the point I paused on?

Duet Wifi is in laser mode with this command -

M452 P6 R255 F6000 I0

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.02RC3(RTOS) (2018-10-17b2)

@jgrouse said in resume.g and using a laser:

G1 R1 X Y Z30 S0 F9000

Try:

G1 R1 X0 Y0 Z30 S0 F9000
G1 R1 X0 Y0 Z0 S0 F9000

That should command the head to 30mm above the pause point, then down to the pause point, and then resume the laser.
