Is it possible to turn off the lights on a FFCP when the print has finished?

M355 is the gcode for toggling case lights on/off, but you'll need to check if your firmware supports it. Take a look here: http://reprap.org/wiki/G-code

Reason I ask is to see about adding it to the ending script section so when print is finished it could turn out the light. Haven't had a chance to try it yet.

Got word that M355 didn't seem to work.

Someone suggested using M146 r0 g0 b0
Again I haven't been able to try yet.

The LED's in my printer go on with using M42 S0 or off with M42 S255 or anything in between 0 and 255

I think a lot of printers use different commands for this, so you may need to try M146, M355, M42, etc and see which one works with your printer

I use M146 on my printer that has LEDs

I think M146 only works with the flashforge dreamer (and any clones of that machine)

Has anyone got this working? It must be possible as ReplicatorG supports it. I'd like to switch off the lights as I have a webcam monitoring print progress and the lights cause it to over-expose.

I've tried M146 r0 g0 b0 to no avail.

As has been said earlier in the thread, if your printer and firmware support a command to turn lights on or off, you can add the relevant command into your ending script. S3D has the capability to allow commands to be included....so if your printer will accept an instruction.....then S3D will be able to give it! You just need to find out what it is.
